Experimental Study on Self Compacting Concrete Withaddition of Super Absorbent Polymer

Abstract

This experimental work focuses on the effect of superabsorbent polymer (SAP) in self-compacting concrete (SCC). The target strength to be achieved is M40. The superabsorbent polymer acts as an Internal curing agent (ICA) which is added at a percentage varying from 0.1 to 0.3 and superplasticizer to about 0.8% with respect to the mass of cementitious materials. SCC is super workable due to its low water-cement ratio, which gives rapid strength, more durability, and best quality. In this study the properties of fresh and hardened concrete were investigated. The workability properties like Slump flow, V Funnel and L Box tests were carried out. The mechanical behaviour and durability study such as Rapid Chloride Penetration Test (RCPT) were alsoconducted on SAP added SCC. SEM Analysis was carried out toidentify the newly formed materials within the concrete system. The concrete added SAP behaves similarly and as like the conventional concrete in strength aspect but varies in case of durability properties.
