High-strength concrete is a type of concrete with compressive strength greater than 40 MPa (megapascals), which is much higher than the strength of normal concrete. High-strength concrete is often used in construction projects where greater strength is required, such as high-rise buildings, bridges, and other structures that need to withstand heavy...

Building material is one of the essential aspects in accommodating the supply and demand of low-cost housing in Indonesia. Recently, several researchers have devoted much time and effort to developing waste recycling for building materials since it is more ecologically benign, particularly for non-degradable waste. This article focuses on recycling disposable diaper waste as composite material for a structural and architectural component of the building based on Indonesian building standards. In addition to offering a broad perspective on the implementation of experimental findings, the design scenario comprised the construction of low-cost housing with a floorplan area of 36 m². The experimental results indicate that disposable diapers waste to use as composite materials of the building has a maximum capacity of 10% for structural components and 40% for nonstructural and architectural components. The prototype housing also reveals that 1.73 m³ of disposable diaper waste can be decreased and utilised for a housing area of 36 m².
... If the heating process activates this subsequent material, it can increase the early strength of cement mortars when used in a low amount [17]. The diaper can be used as a self-cure agent to improve concrete performance when used in a low amount [18]. PET, when used at 5-10% weight, increases the material's compressive strength because it does not absorb water and makes the composite more compact. ...

Disposable diaper recycling has become a major focus in several countries due to environmental concerns. As for overcoming the problem of recycling technology, the use of diaper waste as a material for concrete can be an easier and cheaper option. Although the use of waste disposable diapers as concrete composite material is still very limited, several studies have shown positive results. The addition of disposable diapers to concrete has increased internal curing hydration, improve strength and durability. However, the problem of strength remains a major issue to the development of this concrete. Previous studies concluded that the addition of diapers to concrete is only a maximum of 5%. To further enhance its workability, the addition of a rice husk-based superplasticizer as a concrete admixture was studied in this paper. The variants of the mix design are the addition of disposable diapers of 5% and 10%, with and without superplasticizer. The results show that the addition has no significant impact to reduce compressive strength compared to normal concrete but enhances its workability and mechanical properties. The result increases compressive strength to 4.4% - 6.9% and increases slump value to 2 - 3 times. The result also indicated the variants utilization of disposable diaper concrete for the infrastructure industry.

Disposable diaper waste is a crucial environmental problem today. Population growth is one of the triggers for increasing this type of waste. To overcome this, various studies on recycling diaper waste are a top priority. Some researchers recycle diaper waste as building components, especially concrete. The results of those studies have a positive impact on waste recycling innovation. In this paper, we will try to approach the formula for calculating the recycling of diapers as concrete. In addition, a simple simulation is used to determine the capacity of diaper waste that can be recycled as building material. The study revealed that parameters to calculate waste capacity for disposable diapers is age population of 0-4 years, frequency of changing diaper and mass of diaper. Thus, parameters to be considered for replacement of concrete component by waste materials, especially disposable diapers is density of materials, mass of materials and percentage of replacement Based on the calculation simulation results, the use of diaper waste as a concrete material for road pavement is better to reduce waste production capacity than for building components.

Alkalinity of concrete is crucial because acidity will cause corrosion and lead to horrible structure failure [53,58,59,[62][63][64]. Therefore, pH of both ND and UD are neutral and alkaline making it possible for its application in concrete technology. ...
Diapers are reusable waste. This research presents physicochemical properties of sodium polyacrylate in new (ND) and used (UD) diapers, via wavelength-dispersive X-ray fluorescence (WDXRF), Fourier transform infrared (FTIR), X-ray diffraction (XRD), pH, turbidity and colour. Additional constituents detected in ND, while others were slightly higher in UD. Slight decrease (2000-2500 cm⁻¹, UD) and bulk peaks (3287-3333 cm⁻¹, UD) were observed and functional group at 2897 cm⁻¹ (ND) disappeared showing their role as absorption sites. The pH (6.83-8.50), turbidity (16.3-36.6 NTU) and colour (153-432 Pt.Co) values were obtained. Thus, this provides a baseline reference for diapers application in concrete technology.
