“…This was 16.55% and 23.92% lower compared to the control brick. This observation is consistent with Askar's analysis (ASKAR et al, 2019). It was due to the fact that EPS beads are ultralight particles consisting of 98.0% of air.…”

The construction industry is growing fast alongside the growth of the economy and the population. As one of the major building materials, brick is in high demand for construction purposes. The continuous growth will eventually lead to a shortage of raw materials in long run, such as sand and Ordinary Portland cement. This issue could be resolved by utilizing the waste materials, Expanded Polystyrene (EPS) beads and Silica Fume (SF), in replacement of sand and cement in the production of bricks, respectively. In this study, 120 specimens were produced with EPS beads removed 10% to 15% of sand while SF removed 10% to 20% of cement. The cement-to-sand ratio and water-to-cement ratio were 1:2.5 and 0.5 respectively. The performance of bricks was analyzed in the aspect of compressive strength, density, water absorption, and strength to weight ratio (s-w ratio). EPS beads were found to reduce the compressive strength and density, while SF strengthen the mix thus compensating for the performance loss caused by EPS beads. For construction application, the EPS beads and SF with the replacement of 15% and 10% respectively, were recommended, as it achieved the minimum requirement of the industry.

In general, plastic waste has been growing remarkably. Numerous waste plastic products are generated by manufacturing processes, service industries, and municipal solid waste (MSW). The increase in plastic waste increases concern about the environment and how to dispose of the generated waste. Thus, recycling plastic waste becomes an alternative technique to the disposal of plastic waste in a limited landfill. One of the solutions is to use plastic waste as recycled material in concrete construction to produce what is called green concrete. This research illustrates a summary of studies that utilized polyethylene terephthalate (PET) in concrete as a volume ratio or concrete aggregate replacement. It presents data with regard to mixing design and concrete behavior when PET is used. Moreover, using PET in concrete industries may reduce environmental pollution such as the emission of carbon dioxide and plastic waste disposal problems.

“…While this reduction in weight becomes almost 11% when the WPSF content is 30%. The decrease in the density of concrete with the increase in WPSF content can be attributed to the weight of the WPSF, which is about 98% air [28]. Thus, there will be a decrease in density due to the increase in air content in the concrete.…”

One of the waste materials currently used in the manufacture of lightweight concrete is polystyrene. However, the effects of this material on most concrete properties have not been studied in Libya. In this paper, experimental data for plain concrete were obtained by replacing natural sand with waste polystyrene foam (WPSF) in volume ratios of 0%, 10%, 20%, and 30%. The properties of concrete, such as slump, air content, density, water absorption, compressive strength, flexural strength, free shrinkage, and UPV, were determined experimentally. The findings indicate that as the amount of WPSF in the concrete mix increases, the slump, density, compressive strength, and flexural strength as well as the elastic modulus and UPV of the plain concrete decrease. Conversely, an increase in the replacement level of natural sand by WPSF leads to an increase in air content, water absorption, and free shrinkage. Even though the incorporation of WPSF did not enhance most of the established engineering properties of concrete, the results obtained still fall within the acceptable limits for concrete use in all engineering applications. As such, this type of concrete may be suitable for construction applications that require less thermal and acoustic insulation.
