1. Introduction
In the present-day development method, utilization of earthen-
ware materials has developed step by step as tiles, clean fittings,
and other electrical products like separators. This separator shrub
was utilized in assembling transformers [3]. This kind of Ceramic
waste from enterprises is mounting step by step in handling, ship-
ping, and fixing because of its fragile nature. Compressive quality
was unaltered when artistic waste is utilized mostly to supplement
the ordinary squashed stone course [4]. To decrease the quantity of
earthenware squander stored in landfills or anyplace and help the
common assets, reusing the artistic waste to use as totals in con-
crete has been researched. The principal target of this examination
is to consider the presentation of cement with the earthenware
squander total [5]. The Earthenware chambers are used as storage
for massive and medium-sized towns; a considerable progression
about the assortment, stockpiling and all other more as of late
treatment of local waste for the longer period [6].Correspondingly,
there has been a developing social and political familiarity with
natural issues [7].
1.1. Ceramic waste
Rapid development in industries causes significant issues
everywhere throughout the world, such as exhaustion of regular
natural minerals (river sand) and makes a gigantic measure of
waste material from development and destruction exercises. One
of the best approaches to lessen this issue is to use the squanders
[8]. The structure rubbles gathered from demolished structures
consist of squander solid, tiles, block, steel, and wood. Among
these, the clay tiles are utilized in this task. Because of removing
earthenware squanders from building destruction in a landfill,
the pottery interacts with groundwater and sand and causes harm-
ful impacts [9]. The use of squashed tile total cement is delivered
by total supplants technique, powerful in decreasing both expense
and condition sway.
1.2. Applications of ceramic waste
The need to deal with this waste has got one of the most prob-
lems that need to be addressed for our occasions, requires explicit
activities planned for forestalling wastage. The advancement of
asset recuperation frameworks is a method for misusing the assets
contained inside waste, making some way or another is lost,
diminishing ecological effect [10]. Despite securing the earth,

utilization of such waste offers a progression of focal points.
Besides, reuse likewise offers benefits as far as vitality, principally
when the waste is from oven enterprises where profoundly
endothermic deterioration responses have just occurred, in this
manner recouping the vitality recently joined during the creation
[11].
2. Research significances
The ceramic industry is another rapidly rising industry that pro-
duces more waste in India. Ceramic materials are manufactured
from clay by the following process: molding, drying, and subse-
quent burning. It has been estimated that about 30% of the daily
production in the ceramic industry goes to waste [12]. This waste
is not recycled in any form at present. However, ceramic waste is
durable, challenging, and highly resistant to biological, chemical,
and physical degradation forces. As the ceramic waste is piling
up every day, there is pressure on the ceramic industries to find
a solution for its disposal, if this can be used in concrete, making
it an ideal solution for disposal [13]. Meanwhile, conventional
crushed stone aggregate reserves are depleting fast, particularly
in some desert regions of the world use of inorganic industrial
residual products in making concrete will lead to sustainable con-
crete design and a greener environment [14].
3. Materials and properties
3.1. Ceramic waste
The principal waste coming into the ceramic industry is ceramic
waste, specifically in the powdered form. Ceramic waste is gener-
ated during the process of dressing and polishing [15]. It is also
estimated that 15 to 30% of wastes are produced from the total
raw material used. Although a portion of this ceramic waste may
be utilized in-site, such as excavation pit refill, therefore disposals
of these waste materials acquire large land areas and remain scat-
tered all around, spoiling the aesthetic of the entire region [16].Itis
challenging to find a use for ceramic waste produced Ceramic
waste in concrete to improve its strength and other durability fac-
tors. Ceramic waste can be used as a partial replacement of cement
or partial replacement of fine aggregate sand as a supplementary
addition to achieve different properties of concrete (Fig. 1).
3.2. Aggregate
An aggregate that plays an essential role in concrete occupies
70% to 80% of the concrete mass. The aggregate will reduce the
air voids in the concrete and gets more strength of the concrete

[17]. So, that concrete will reduce shrinkage and become more
cost-efficient.
3.3. Coarse aggregate
The coarse aggregate quality will fall on the requirement of
Indian Standards (IS):383 codal provisions retain on sieve from
20 mm to 4.75 mm [1]. The Specific gravity of coarse aggregate
and water absorption are tabulated in Table 1, and Fig. 2 shows
the water absorption.
3.4. Fine aggregate
The fractions from 4.75 mm to 150microns are termed as fine
aggregate. The river sand is used in combination as fine aggregate
conforming to the requirements of IS: 383. The river sand is
washed and screened to eliminate harmful materials and oversize
particles [18] (Fig. 3.Table 2.Table 3).
3.5. Water
Water is an essential ingredient of concrete as it participates in
the heat of hydration reaction with cement. Since it helps to form
from the strength giving cement-gel; the quantity and quality of
water must be looked into very carefully.
3.6. Cement
The cement used in all mixtures is commercially available Port-
land pozzolana cement of 53 grade confirming to IS: 12,269 were
used in this study. The specific gravity of cement is 3.15. The initial
and final setting times of cement were found as 30 and 600 min,
respectively, setting time. Cement, when mixed with water con-
crete, forms a paste, which gradually losses. Its plasticity and
results in hard mass. In this setting process, a range is reached
when cement paste is sufficiently rigid to withstand a definite
amount of pressure. The time taken to reach this stage is called
the setting (Table 4).

4. Experimental program
4.1. Experimental plan
The main aim objective of this research is to replace the waste
ceramic materials is to grain as fine particles and replaced them
with fine aggregate. This experiment has carried out to find a bet-
ter understanding of factors that can increase concrete’s strength
and properties to determine the value of ceramic waste as aggre-
gate in the concrete. The concrete cubes were tested to find the
value of compressive strength; cylinders were cast for testing split
tensile strength of the concrete cylinder, and concrete beams were
cast to determine the value for flexural strength at various age of
curing 7 days and 28 days with a concrete grade of M30.
4.2. Mix proportion
Mix design was calculated for M30 grade concrete according to
the Indian standard code provision IS 10262–2009 [2], tabulated in
Table 6. Fine aggregate was replaced with crushed ceramic waste
aggregate at different percentages as follows 0, 5, 10, 15, and 20%
in the concrete composition. To determine the value of Mechanical
properties of fine aggregate (river sand) and fine ceramic aggre-
gate, which is extracted from the waste ceramics, were obtained
through experimentation work.
4.3. Preparation of concrete and size of Specimen
The quantities of the concrete constituents were obtained from
the Indian Standard Mix Design (IS 10262:2009) [2]. The mixed
proportion of concrete was prepared in the laboratory. The follow-
ing materials were used cement, fine aggregate, and coarse aggre-
gate mixed in a particular mix ratio in the form of a dry state to
obtain uniform color and calculate the water-cement ratio, and it
is mixed with the dry mix. Concrete will be poured in the cube
mold, cylinder mold, and beam mold by tampering with the fresh
concrete to eliminate the air voids, shown in Fig. 4. After 24 h, all
molds should be unmolded and remove the concrete cubes, cylin-
ders, and beams; the cast is then kept for curing in two different
stages of the test at 7 days and 28 days in into the water tank.

5. Test results and discussions
5.1. Workability
A new concrete test has been conducted to determine the work-
ability of concrete. The slump cone test was conducted out in con-
crete batches for various percentages of waste ceramics, as shown
in Table 7. The water-cement ratio improves the workability of the
concrete, with the addition of ceramic waste materials as fine
aggregate. The slump value is as shown in the Fig. 5.
5.2. Compressive strength of concrete
Compression tests were conducted as per the Indian standard
code IS 516(1959), Concrete cubes of size 150mmx150m-
mx150mm for the following mix proportions of 5, 10, 15, and
20% replacement of aggregate with waste ceramic materials. The
cubes were cast and kept for curing at two different ages, 7 days
and 28 days, in the water tank. Then, the concrete cubes were
tested with a compression testing machine (CTM), which has a
capacity of 2000kN, which is shown in Fig. 6. The concrete cube
specimens were loaded until it reaches the failure mode. The
experimental value of the compression test is tabulated in Table 8,
and the comparative study of two different age of curing is shown
in Fig. 7.
5.3. Flexural strength of concrete
The test could be performed following as per code IS 516 –1959.
If the flexural strength would be the same as the tensile strength,
then the material becomes homogeneous. Most materials have
small or large defects, which act to concentrate the stresses locally,
effectively causing a localized weakness. The test was performed
on beams of dimensions 100 100 500 mm to determine the
flexural strength. The casted beams are kept in curing for 7 and
28 days by immersed underwater (Fig. 8.Fig. 9.Fig. 10.Table 9).

... In general, ceramic waste partially replacing aggregates (fine aggregates and coarse aggregates) in concrete can lead to a decrease in slump or slump flow [54][55][56][57][58]. This may be attributed to the more irregular shape [59,60], rougher surface texture [59,61], and higher adsorption [61,62] of ceramic waste in contrast with natural aggregates. ...
... Relatively few studies had reported that ceramic waste as a substitute for fine aggregates in concrete caused a drop in the compressive strength of concrete [55]. Alves et al. [26] added bricks as partial fine aggregates to concrete, and it indicated that the compressive strength of concrete could decrease with an increase in the replacement ratio of bricks to fine aggregates. ...
... Ceramic tile waste had been used as a substitute for fine aggregates in concrete, and its effect on the flexural strength of concrete in different studies was not the same. Johnson Daniel et al. [55] used ceramic tiles as substitutes for 5%, 10%, 15%, and 20% of the fine aggregates in concrete and found that the 7 d flexural strength of concrete containing ceramic tiles was higher than that of the control concrete, except for the concrete in which 20% of the fine aggregate was replaced with ceramic tiles; however, the 28 d strength of concrete containing ceramic tiles was lower than that of the control concrete despite the replacement ratio. According to Yahya et al. [59], ceramic tiles were collected from construction site areas. ...

Ceramic waste (CW) has a significant negative environmental influence on the society. However, CW may benefit the environment if it is handled carefully and recycled in concrete production. Recycling CW may lessen the demand for raw materials and waste disposal, thereby preserving natural resources and lowering greenhouse gas emissions. Numerous studies discuss the possibility of CW utilization as concrete ingredients. However, data are spread, making it difficult for the reader or user to assess the benefits and drawbacks of using CW in concrete, which limits its applications. To study the benefits and drawbacks of using CW in concrete and provide the guidelines to the consumer with relevant information, a detailed review is required. Therefore, this study is carried out to collect all relevant updated information from published articles. The major topics of this article include the general history of CW, physical and chemical features, and the influence on concrete parameters including fresh, strength, elevated temperature, and cost benefits. Results indicate that CW decreased concrete flowability and strength. However, with up to 10% substitution, the results are satisfactory, and concrete can be used for a normal-strength structure. Furthermore, the review also identifies the research gaps that need to be investigated.
... However, these RCBs' yield stiffness (S y ) and stiffness under maximum force (S Pmax ) decreased by 20% and 80%, respectively, compared with the reference RCBs. The stiffness tended to decline depending on the amount of CP, and the obtained results are compatible with similar literature studies [66,67]. Because of all these reasons, CP can be utilized up to 10% with caution since it created a reasonable decrease in the strength and stiffness of RCBs. ...
... Numerous studies have compared the use of ceramic waste with concrete (Pacheco-Torgal & Jalali, 2010; Prahara & Meilani, 2014;Shruthi et al., 2016;Elci, 2016;Anderson et al., 2016;Kannan et al., 2017;Rashid et al., 2017;Chen et al., 2017;Bommisetty et al., 2019;Huseien et al., 2020;Daniel & Sangeetha, 2020;Goyal et al., 2021 have investigated the utilization of ceramic waste in different percentages of replacement for fine and coarse aggregates in concrete. The results showed that it would increase both mechanical properties and durability properties at different percentages of replacement. ...
... Awoyera & Britto [14] have fully replaced sand in foamed concrete with pulverized ceramics with the presence of fly ash and aluminum powder leading to concrete strength closer to the one of conventional mixture. In addition, the replacement of fine aggregate in concrete with ceramic wastes up to 20% could improve the mechanical properties of concrete [15], [16]. Replacing of 21% sand in concrete with recycled waste glass leads to optimal performance of concrete for both compressive strength and acid resistance [17]- [20]. ...

This paper presents an experimental investigation on the effect of the partial replacement of fine aggregates in concrete with available local Natural Pozzolan (NP) in Al-Madinah Al-Munawarah, Kingdom of Saudi Arabia (KSA). The utilization of NP has reduced the density of concrete and improved its mechanical properties. The Saudi Building Code has recommended using pozzolan with a special type of cement in the case of concrete exposed to high percentages of sulfate. 48 concrete cylinders with dimensions of 150×300 mm have been prepared. The cylinders have been divided into two groups according to the level of cement replacement with Silica Fume (SF). The first group consists of 24 concrete cylinders with Natural Sand (NS) substitution with NP by volume at replacement levels of 20%, 50% and 100% without SF. The second group consists of 24 concrete cylinders with sand substitution with NP by volume at replacement levels of 20%, 50% and 100% in addition to the presence of 5% cement replacement by weight with SF. The concrete cylinders have been tested after 28 days. The utilization of NP and SF has showed a noticeable influence on the mechanical properties of concrete. Therefore, based on the results, the replacement of 20% of fine aggregate and 5% of cement in concrete with NP and SF, respectively has increased the compressive and tensile strength of concrete.

Waste materials are a major issue for environmental challenges, due to greenhouse gas emissions, reduce natural resources, demolition storage, and energy consumption and generate pollution. The growing concern for sustainable construction practices has increased interest in incorporating recycled materials into concrete production. Therefore, numerous research studies conducted to explore the feasibility of utilising waste glass, ceramic and rubber as recycled fine aggregates (RFA) in concrete. This review paper presents a comprehensive comparative review of the utilisation of recycled waste glass, ceramic, and rubber as fine aggregate (FA) in high-performance concrete (HPC), focusing on the mechanical properties such as modulus of elasticity, compressive strength, tensile strength, and flexural strength, as well as their impact on durability characteristics including workability, density, water absorption, drying shrinkage, and chloride-ion penetration. The utilisation of waste glass and waste ceramic as RFA in concrete demonstrated stable and improved mechanical and durability performance compared to waste rubber. Although, the incorporation of waste rubber as RFA showed a reduction in mechanical and durability performances, concrete containing a lower percentage of waste rubber as RFA still exhibited satisfactory mechanical performance. This evaluation indicates that RGC performs optimally when incorporating up to 30% RFG, while RCC exhibits the best performance with a replacement of 50% RFC. In contrast, RRC demonstrates optimal performance with a lower percentage of RFR, specifically less than 25%. Therefore, proper mix design and optimization are crucial for achieving desired concrete properties. However, there has not yet been a comprehensive comparative review concentrating on mechanical and durability properties aspects of waste glass, ceramic and rubber in HPC, particularly as fine aggregate. Therefore, the findings of this review provide insights into both the potential benefits and limitations of utilising these recycled materials in HPC. Additionally, this comprehensive comparative review can serve as a foundational reference for future research efforts and contributing to the development of more sustainable and environmentally friendly concrete solutions.

The scientific community recognizes that the depletion of natural resources and solid waste management pose inherent challenges in building material production and disposal, particularly in concrete manufacture and deconstruction. Recycling and reusing construction waste is proposed as a solution to these issues in the literature. Repurposing waste materials as additives in concrete represents an alternative approach. For instance, ceramic tile waste (CTW) may replace a portion of the aggregate and cement used in concrete. This study extensively examines the literature on cement-based composites that utilize CTW in lieu of cement and aggregate. A thorough evaluation of mechanical, durability, and fresh properties is conducted. The physical and chemical attributes of CTW are based on extensive scientific research. Prior studies suggest that the use of ceramic tile aggregate (CTA) to concrete in the appropriate proportions could enhance its durability and strength. Finely ground ceramic tile powder (CTP) with high silica content can potentially enhance the strength and durability of concrete, according to prior research studies. The impact of CTP on the chemical resistance, drying shrinkage and fire resistance abilities of concrete are subsequently evaluated. Employing waste materials as a concrete component in a circular economy to promote environmental protection and the development of sustainable cities and communities has received broad support from the academic community.

Based on orthogonal experiments, an ordinary Portland cement (OPC)-fly ash (FA)-silica fume (SF) ternary cementitious material system was developed. The ultra-high-strength lightweight concrete (UHPLC) with a strength exceeding 100 MPa was prepared using pottery sand (PS) and hollow glass microspheres (HGM) as the weight-reducing material and steel fibers as reinforcement. Through workability, apparent density, strength, and early autogenous shrinkage tests, as well as SEM examinations, the effect of various material parameters on the basic performance of UHPLC are investigated, and their mechanisms were explored. The results revealed the optimal mix ratio of OPC: FA: SF: PS: HGM =1: 0.200: 0.133: 0.533: 0.067, a water-binder ratio of 0.16, and the volume ratio of steel fibers of 2%. Under steam curing at 90°C for 48 h, the prepared UHPLC had an apparent density of 2031 kg/m ³ , compressive/flexural strengths of 112/16 MPa, a slump/expansion of 260/590 mm, and specific strength of 0.055, achieving the goal of lightweight and high strength. As the filler of composite materials, HGM can achieve lightweight and high strengthening of cement-based materials. HGM had a large water demand, increasing the autogenous shrinkage of UHPLC to a certain extent. The incorporation of steel fibers significantly increased the strength and apparent density of UHPLC, and its high elastic modulus inhibited the UHPLC shrinkage.

Concern over sustainability in the construction industry is growing. Engineered cementitious composites (ECC) have the potential to reduce the carbon and energy footprints of the built environment due to their crack resistance and self-healing properties. Over the last decade, continuous efforts have been made in the development of greener ECC. These efforts can be broadly classified by the use of greener binders, fillers, and fibers. This paper reviews recent progress in the exploration of more environmentally friendly and perhaps even more economical materials, and points to research needed for further enhancing the mechanical or durability properties of ECC. Specifically, the significant contribution of fly ash (FA) as a green binder, and alternatives that address its possible shortage are discussed. The adoption of greener sands (natural or recycled) and fibers (man-made or natural) based on physical, chemical, and mechanical perspectives is evaluated. Further explorations of the ductility of high-volume limestone calcined clay (LCC)-blended ECC, interactions between ground-glass pozzolans (GP) and ceramic powder against alkali-silica reaction (ASR), chemical interaction between recycled ceramic aggregate and cementitious matrix, characteristics of local polyvinyl alcohol (PVA) fibers, and the combined effects of eco-friendly ingredients are recommended.

18 La industria cementera está buscando vías alternativas que permitan dar solu-ciones efectivas a los elevados consumos energéticos e implicaciones medioam-bientales que conlleva la fabricación de cemento. Entre estas vías, está la utilización de materiales alternativos, ya sean como sustitutos parciales de los combustibles, de las materias primas o del propio clínker. En el presente trabajo se estudia la reactivi-dad y la aptitud a la cocción de unos crudos de cemento que incorporan residuos cerámicos, procedentes de baldosas obtenidas con composiciones de arcillas de cocción roja y de cocción blanca o mezclas de ambas, como materias primas alternativas. Los resultados obtenidos han demostrado la validez tecnológica de los nuevos crudos que incorporan esos residuos. La reactividad y la aptitud a la cocción de los nuevos crudos son superiores a las de un crudo convencional, siempre y cuando el tamaño de las partículas de los residuos sea inferior a 90 µm. Los estudios realizados en torno a las emisiones de CO 2 en la cocción de dichos crudos muestran que dichas emisiones se reducen en los crudos con residuos cerámicos entre un 2,3 y un 4%, dependiendo de la naturaleza del residuo. La composición y distribución de los minerales en los clínkeres obtenidos son comparables a los de un clínker fabricado a partir de materias primas convenciona-les. Debido a la presencia de óxidos tales como ZnO, ZrO 2 y B 2 O 3 en la capa esmal-tada de las baldosas cerámicas que componen los residuos, aumenta el contenido

Ceramic waste from ceramic and construction industries is one of the most important parts in the global volume of construction and demolition waste (CDW). Ceramic waste may have several uses, one of which as coarse aggregate for concrete artefacts. Within a research campaign in course at Instituto Superior Técnico (IST), concerning the reuse and recycling of CDW, the viability of replacing primary limestone aggregates with ceramic waste on the production of concrete pavement slabs has been studied. Compression and bending tests previously performed have shown the mechanical suitability of replacing, at least partially, limestone aggregates with ceramic recycled ones. In this paper, the results of the water absorption tests, either by capillarity or by immersion, and the results of the abrasion resistance tests are presented, all related to long-term concrete durability.

Use of hazardous industrial wastes in concrete-making will lead to greener environment. In ceramic industry about 30% production goes as waste, which is not recycled at present. In this study an attempt has been made to find the suitability of the ceramic industrial wastes as a possible substitute for conventional crushed stone coarse aggregate. Experiments were carried out to determine the compressive, splitting tensile and flexural strengths and the modulus of elasticity of concrete with ceramic waste coarse aggregate and to compare them with those of conventional concrete made with crushed stone coarse aggregate. The properties of the aggregates were also compared. Test results indicate that the workability of ceramic waste coarse aggregate concrete is good and the strength characteristics are comparable to those of the conventional concrete.

Concrete is the basic engineering material used in most of the civil engineering projects. It is extremely used because of the ability in possessing high compressive strength and can be moulded into any desired shape. In order to overcome the poor tensile strength of concrete, fibers are introduced in the matrix. In this research work, burr wastes obtained from CNC turning process in lathe industry were disposed as wastes in open lands in the proximity of the industries causing an hazard to the environment. Hence, these wastes were tested as fiber material in the form of micro-reinforcements in the concrete. Burr wastes were added to the concrete in volume fractions Vf = 0% to 2.0% and tested for its split tensile strength, compressive strength and flexural strength. The results of the experimental tests revealed that the compressive strength and flexural strength of burr waste concrete increased from 16.16% to 23.36%and 117% to 124% respectively for Vf = 0.5% to 2.0% at 28 days strength in comparison with concrete made without burr waste. The tensile strength of burr waste concrete increased upto 6.06% for Vf = 0.5% at 28 days strength when compared to conventional concrete. From the experimental investigation, it was observed that the addition of burr wastes as micro reinforcements in the concrete had significant improvement in terms of concrete strength.

The construction industry is going through a rapid phase of improvement on various aspects one of which is enhancing the strength of concrete by utilizing various natural fibers and mineral admixture available. This project revolves around the study on strength characteristics of concrete reinforced with glass fiber and also using silica fume as a partial replacement for fine aggregate in conventional concrete. The performance of the concrete against compression, tension and flexure is studied in detailed and discussed. The glass fiber are mixed in concrete as an additive by 0.8 % to the overall weight of concrete and 25% of cement is replaced with silica fume to improve the overall performance and strength of concrete. The usage of glass fiber in concrete has lead to reduction in the development of micro cracks at the initial service period and the use of silica fume seems to increase the strength and overall structural rigidity of the structures. By reinforcing glass fiber in concrete and replacing the cement with silica fume has enhanced the strength by improving the mechanical properties of the concrete compared with conventional concrete. The mix ratio suitable to produce a concrete specimen of compressive strength 30N/mm 2 is taken as the control specimen. The test result indicates that using silica fume in glass fiber reinforced concrete has enhanced the strength by more 20% when compared to normal concrete.

In order to reduce the volume of ceramic waste from the construction industry, it is possible, among other applications, to use it as aggregates in the production of non-structural concrete artefacts. The main characteristics of such aggregates as well as those of the fresh and hardened concrete made with them (after a standardized pre-saturation procedure) are presented here and compared with those of conventional materials (primary stone aggregates and the concretes made exclusively with them), within a larger experimental investigation to maximize the reuse and reutilization of construction and demolition waste. The results show that there is a potential for the use of these ceramic aggregates in elements in which the primary requirement is not compressive strength but tensile strength and abrasion resistance, such as for concrete pavement slabs.

The recycled and re-valuation process of waste materials involves studies lead to a deep acknowledges of them, finding applications for their intended use. The waste materials from ceramic products can be recycled into the construction sector, as arid or pozzolanic materials. The current work deals with the incorporation of ceramic materials in these two different ways, checking the behaviour of the elaborated mortar by mean of laboratory tests. Also, tests are developed in factory, using these as components for precast concrete tiles.Todo proceso de reciclado y revalorización de residuos implica estudios encaminados a un conocimiento profundo de los mismos, de forma que se busquen aplicaciones concretas de uso. Los materiales de desecho procedentes de productos cerámicos pueden ser reciclados dentro del sector de la construcción, ya sea como áridos o como materiales puzolánicos. El presente trabajo aborda la incorporación de materiales cerámicos desde estas dos vertientes, comprobando, en cada caso, el comportamiento de los morteros elaborados mediante ensayos de laboratorio. También se llevan a cabo pruebas en fábrica, siendo utilizados como componentes en prefabricados de hormigón.
