Experimental Study on Self Curing Fiber Concrete

Abstract

Water is the major demand in today’s world. For concrete water curing needs to be done minimum of 28days. Internal water curing is the one way of finding root cause of shrinkage on concrete. This study is about self curing concrete .Self curing concrete is nothing but curing takes place internally. Super Absorbent Polymer (SAP) is act as a curing agent. The dosage of SAP used is 0.3% of binder content. The grade designated is M40. Using of SAP gives the strength more than that of conventional concrete. And also Sisal fibreupto 0.4% added to the concrete to improve its durability. Mechanical strength and ability of hardening were found by the concrete using SAP & Sisal fibre addition. And also the long term properties such as a water absorption, presence of voids, carbonation depth were tested at 28, 56 and 90 days.
