Abstract

This article presents the super absorbent polymer (SAP) performance in recycling aggregate concrete. In conventional concrete the coarse aggregate is replaced with recycle aggregate in the proportion varying from 0,25,50,75 and 100%. The mix with 0%RA is considered as reference or control concrete. The SAP was added as to all recycle aggregate concrete (RAC) mixes by weight of cement in the proportion ranging from 0.1,0.2,0.3,0.4 and 0.5%. The significance of the SAP in RAC was studied based on compressive strength of cube and its behaviour is studied at 7, 14 and 28 days and the analysis is supported with SEM images. At all stages the strengths are compared with control concrete, and it was found that 0.2% SAP is effective for all RAC mixes.
