History of cementing material is as old as history of engineering construction such as in monument construction of Egypt, Greek, India and Rome. The usage of concrete dates back to starting of 20th century after discovery of cement. Conventional concrete making constituents are cement, fine aggregates, coarse aggregate, water and mineral or chemical admixtures. On the other hand, usage of natural aggregates from river beds/banks and other sources such as rocks can seriously create environmental threats. Analysis was made by replacing RCA in following percentage 0%, 25%, 50%, 75%, 100% and all samples have 25% & 50% ( by weight ) quarry dust as fine aggregate replacement.
