Abstract

Due to the ability of high dosage of Super Absorbent Polymer (SAP) to effectively seal cracks in concrete with a resulting decrease in strength, there is a need to find alternative methods of using SAP without much strength loss. The aim of the present study is to evaluate the performance of SAP when blended with Metakaolin (MK). The Absolute Volume method was applied for this study. Hardened state properties of compressive strength was evaluated. Cement replacement with MK was carried out at (4%, 8%, 12% and 16%) and (0.25%, 0.5%, 0.75% and 1%) for SAP. The compressive strength properties is compared for 0.2 % 0.25 water binder ratios at 7, 14 and 28 days. The result showed that the use of MK and SAP improves the compressive strength properties of concrete. The optimum results were observed at 12% MK and 0.5% SAP. The maximum comprehensive strength at 28 days was found to be 91.51 Mpa and 84.99 Mpa for 0.2 w/b % 0.25 w/b respectively. A decrease in strength was observed as the dosage of SAP exceeds 0.5% replacement.
