EFFECT ON COMPRESSIVE STRENGTH OF CONCRETE INCORPORATING RECYCLED AGGREGATE CONCRETE WITH FLY ASH AS CEMENT REPLACEMENT

Influence on compressive strength of concrete incorporating recycled aggregate concrete and fly ash as replacement of cement is investigated in this paper. Recycled concrete aggregate (RCA) is replaced by three different percentage 0%,50%,and 100% with the natural coarse aggregates (NCA) . Fly ash (FA) is replaced as 0%,15% and 30% of cement. Water/cement ratio is taken as .45 throughout the experimental programme. The compressive strength of concrete is measured after 7 and 28 days of curing and compared with the normal concrete. The results shows decreased compressive strength of concrete specimens incorporated with recycled aggregate and fly ash https://www.ijiert.org/paper-details?paper_id=14089
