EFFECT OF SUPER ABSORBENT POLYMER ON STRENGTH OF

Abstract: SAP (Super Absorbent polymer) is one of the smart materials with a great scope in civil engineering. SAP can effect the concrete in various ways and aspects like crack, shrinkage, tensile strength and compressive strength. In this study we are going to study the effect of SAP on the strength of concrete mainly and other aspects too.
