Abstract :
High performance concrete (HPC) is popular for its low water-to-cementations materials ratio (w/cm). Because of this low w/c ratio and rapid hydration, proper curing is essential at the earliest time. This paper explores the use of Super Absorbent Polymers (SAP) and Light Weight fine Aggregates (LWA) as internal curing material. Mix M2 is achieved by adding SAP at 0.3% weight of cement and in mix M3 is obtained by replacing 25% weight of LWA to fine aggregates. Strength and durability of these HPC are studied experimentally and the results show greater strength with LWA mix. Load carrying capacity of the beams in flexure and shear also greater in LWA mix and the durability study results reveal that mix with SAP is better compared to the other two mixes.
