Experimental and analytical study on properties of self-curing concrete

Abstract

Proper and complete curing in concrete is a predominant problem prevailing in the field of construction and management. Hence, to ensure complete curing in concrete, a supplementary self-curing agent can be added. The current investigational study observes the effects of self-curing agent Poly Ethylene Glycol (PEG) on various properties such as compressive strength, split tensile strength and flexural strength at discrete proportions of 0.5%, 1.0%, 1.5% & 2.0% by weight of cement. Also, the properties of concrete are predicted by the regression analysis. The amount of PEG to be added is optimized to be 1.5% by the weight of cement. Regression coefficients of 0.971 and 0.891 shows a proper correlation between compressive strength and flexural strength and also between compressive strength and split tensile strength.
