Recycled Concrete Aggregate - A Substitute to Natural Coarse Aggregate
The study deals with the investigation undertaken to examine the possibility of using recycled concrete aggregate (RCA) as a substitute to natural coarse aggregate (NCA). The concrete specimens were cast by partially replacing cement by fly ash, and NCA was replaced by 30%of RCA. Twenty % replacement of cement by fly ash gave optimum results for compressive strength, split tensile strength and flexural strength.
