Influence of Recycled Coarse Aggregate on Properties of Concrete
Abstract: This study focuses on the influence of recycled coarse aggregate (RCA) on properties of concrete. Five different mixtures of RCA replacement comprising 0, 25, 50, 75 and 100% RCA were used. It was found that workability, saturated bulk density, compressive strength and flexural strength decreases with increase in RCA content in concrete. 100% manually RCA concrete passed the 17 kN/m2 compressive strength limit generally acceptable for concrete work of non-high …

A Review on Using Recycled Aggregate with Various Pozzolans in Geopolymer Concrete
Abstract: Reducing the use of natural resources is crucial to solving the global issue of CO2 emissions. Concrete can be produced sustainably by using recycled aggregates and geopolymer binders, which are environmentally benign alternatives to traditional components. Carbon footprints can be reduced by using these materials instead of ordinary Portland cement and natural aggregates. Among all the combinations, recycled coarse aggregates (RCA) and geopolymer concrete have garnered attention as a viable …
