Recycled aggregate pavement in bituminous can be repercussion to mitigation in the exhaustion of rudimentary aggregate and asphalt, orientation to alleviation in the quantities of tailings organized into the garbage dumps. This research aimed to investigate the performance of Hot Mix Asphalt (HMA) surface with recycled concrete aggregate (RCA) as a...

Reactive powder concrete (RPC) is one of the distinctive kinds of concrete whose benefits are high mechanical performance and durability. It contains a high content of cement, which means a high amount of carbon dioxide emitted during manufacturing. Scientists have tended to search for a way to reduce environmental damage, and one solution is to pa...

As cement production causes 7% to 8% of global carbon dioxide emissions, many efforts have been made to reduce the consumption of cement. Using pozzolan (usually fly ash) as additional material with cement is one of these methods. In this paper, the impact of adding Nano fly ash as a partial substitution of cement weight was studied in self-compact...

This research aims to study the influence of using the Nano-silica in high performance concrete subjected to external sulfate attack with different levels. Four concrete mixes were prepared by using two types of Portland cement: ordinary and sulfate resistant cement. From each mix, cubic concrete specimens were cast and subjected to different expos...

Reactive powder concrete (RPC) is a special type of concrete that has excellent properties, especially compressive strength. However, one of the disadvantages of RPC is that it has a high cement content, which can reach 1000 kg/m³. Because of the high cost of producing cement and the greenhouse gas emissions associated with its manufacture, researc...

The reactive powder concrete (RPC) is one of the special concrete types that characteristics with high cement content which means high production cost and CO 2 emissions to the atmosphere. Therefore, to enhance the environment as well as to develop green RPC, alternatives to cement, such as supplementary cementitious materials (SCMs) were used. Lim...

During many tests on ground water sample that were carried out in the labs of Babylon environment directorate, Radon among many pollutants was encountered in concentrations exceeded the allowable limits according to WHO. Hashyimia unconfined aquifer with an area of about 100 Km 2 was found to be polluted with Radon (222 Rn) with concentrations exce...

This study aims to investigate the effect of ternary combination of silica fume, and glass and ceramic waste as a partial replacement of cement on selected properties of mortar in the presence of steel-polypropylene hybrid fibers. Thirteen mixtures have been made: one control mix and twelve mixes in which the cement has been replaced by constant pr...

The fast growth in the construction sector has made the concrete one of the most essential materials in the world. Concrete industry consumes massive amounts of raw materials, such as fine and coarse aggregate. Nowadays the increasing amount of waste construction materials causes environmental problems. Certainly, the sustainable solution is to ado...

Environmental pollution and the relatively high cost of waste disposal has been a major focus for scientists around the world, leading researchers to find a solution to reuse waste materials in different applications. Iraqi people consume hundreds of tons of black tea each year, which produce a large quantity of the used tea, leaves as waste. These...

This paper aims to investigate the influence of Silica fume proportion ratio in respect to the total amount of binder on compressive strength of reactive powder concrete cured in two curing systems. Four ratios of Silica fume (0%, 15%, 25% and 35%) as replacement of cement weight were considered. After de-molding, two curing systems were used: the...

The purpose of this study is to present an evaluation of the properties and characteristics of asphalt concrete of several hot mix asphalt (HMA) from five factories in Al-Hilla city. The research is divided into two parts. The first part included the laboratory analysis of samples. The second part is evaluation of results according to standard spec...

2D groundwater model derived from a partial differential Laplace's Equation and 2D environmental model based on advection dispersion 2nd order differential equation have been designed and fitted to (110km2) Hashyimia unconfined aquifer. The groundwater model has been issued to capturing the a polluted groundwater flow field by a dumping site wherea...

This paper presents the influence of nano-metakaolin addition for production self-compacting concrete (SCC). Nano-metakaolin material was used at four percentages (0, 1, 3 and 5) % as partial replacement by weight of cement [Reference mix (PC), (1%, 3%, 5% nano-metakaolin)(1, 3, 5 NMK)]. This research studied the influence of nano-metakaolin materi...

White crushed Aggregate of Kerbala quarries was used successfully in production of HSC . Compressive strength and Elasticity as well as to rupture and splitting strengths were tested as destructive tests . UPV was tested also as Non - Destructive tests

This research aims to evaluate using the crushed gravel of Kerbala quarries in product self compacting concrete (SCC) , American method (ACI) and (Common mix design method for SCC) are used to design the concrete mixes, the mix proportion of these mixes is (1:1.8:2), and water cement ratio is (0.5) the work involves four mixes, the first without an...

Abstract This research presents a comparison study of physical properties between Iraqi and Iranian perforated clay bricks. 300 samples of perforated clay bricks are randomly selected from the production of five Iraqi factories and five Iranian factories which are available in local markets ( 30 bricks from each factory ). All samples are selected...

ISA property was studied for SCC and NCC as well as Compressive Strength .Tests showed that ISA of SCC was about 5 times less than NCC , also strength was about 25% higher than NCC at the age 0f 28 days

A mathematical model for groundwater motion in three dimension hydrogeologic heterogeneous media at Al Hawija Area (4222km 2 in extent) is developed. The theory of superposition is applied at the media and the results are verified using a theoretical background of Darcey's Law and Theis Equation for the confined and unconfined aquifers at the area....
