This study presents a unique methodology for investigating the properties of Metakaolin Coarse Aggregates (MCA). The NaOH ratios were varied as 8M, 10M, 12M, and 14M, while the NaOH to Na 2SiO 3 ratio was maintained at 0.5 entire study. The liquid-to-binder ( L/B) ratios set at 0.3, 0.35, and 0.4...

In this investigation, coconut shell, a lightweight agricultural waste, is used to completely replace coarse material. Based on previous findings, it is suggested that coconut shell be used as coarse aggregate in structural lightweight concrete. Therefore, the purpose of the study was to develop...

Industrial waste in engineered concrete mixes is an enormous step towards sustainable development. Polyurethane foam waste (PUFW) is mainly generated by the refrigeration, automobile, and construction industries. Day by day, large amounts of PUFW are incinerated and disposed of in landfills, which...

Conventional concrete is heavy which contributes to more dead load, resulting in higher cost of construction, more labour, difficulty in transportation of materials and so on. These impediments can be reduced by using lightweight concrete instead of the conventional concrete. In this study, an...

Nowadays cement industry power plant bed wastes can be used to create aerated concrete blocks for widespread usage in the construction sector instead of sand. The optimum materials for building enclosures for a variety of uses include aerated concretes. To enhance the physical and mechanical...
