The Effect of Super-Absorbent Polymer as a Self-Curing Admixture on the Performance of Mortars
Super-absorbent polymer (SAP) was used as a self-curing admixture for cement-based materials. Two types of super-absorbent polymer and effect of super-absorbent polymer on fluidity and mechanical properties of mortars were investigated. The performance of the mortars cured for different ages was tested. The results showed that SAP could play a role of reserving water and reserving water of SAP particles A with an average diameter of 180 mm was more effective than that of SAP particles B with an average diameter of 80 mm, the optimal performance of reserving water was obtained at 0.07 wt.% of SAP particles A; Mechanical properties of hardened mortars with SAP particles A were better than those with SAP particles B, the favorably experiment ratio was 0.05 wt.% of SAP particles A.
