Abstract

Dearth of natural coarse and fine aggregate has severely affected the construction industries worldwide. Recycled Concrete Aggregate (RCA) may be a compatible substitute to fresh aggregate, provided they are treated prior to their applications in concrete. Overall quality of the RCA depends on the aggregate parent material and present condition of the old concrete from which RCA was extracted. Experiments were performed on M20 and M25 concrete mix designs prepared using RCA in various combination. Influences of polymeric treatment on recycled aggregate concrete (RCA) and its water absorption capacity was analysed thoroughly. Results indicate that in polymeric treatment, compositions of the polymers, their concentration and duration of treatment directly or indirectly affects the strength and water absorption capacity of RCA. Good improvement in compressive strength and water absorption capacity of RCA was obtained after treatment, which proves the significance of polymeric treatment methods. This study will be very useful for promoting the application of RCA in road and building construction and preventing its disposal as a waste.
