Effect of superabsorbent polymer in self-compacting concrete
This research work focuses on the effect of Superabsorbent polymer (SAP) in Self Compacting Concrete (SCC) by evaluating the compressive, tensile and flexural strength at 28 days. The materials taken to manufacture Self Compacting concrete are the weight of cement, coarse and fine aggregate, fly ash and three chemical admixtures were identified. Experimental works by casting different trails of cubes size 150mmx150mm, cylinder size 150mmx300mm and beam of 1800x150x200 mm was carried out and allowed for self-curing. It is concluded that 2% of super plasticizers, 0.5% of Viscosity Modifying Agent and SAP is optimum to use in SCC mix of M40 concrete. Beyond which when added leads to delay in setting time and strength tends to reduce.
