An Experimental Analysis on Properties of Self Curing Concrete Using PEG4000 and PVA

Abstract

Curing is the process of controlling the rate and extent of moisture loss from concrete during cement hydration. It may be either after it has been placed in position there by providing time for the hydration of the cement to occur. Since the hydration of cement does take time – days, and weeks rather than hours – curing must be undertaken for a reasonable period of time if the concrete is to achieve its potential strength and durability.

The concept of self-curing agents is to reduce the water evaporation from concrete and hence increase the water retention capacity of the concrete compared to conventional concrete. The purpose of this project is to study the effect of PVA (Poly Vinyl Alcohol, a water retaining alcohol) in curing process of concretes. The PVA& PEG are mixed of a sand concrete in various proportions 0%, 1%, 2%, 3% polyvinyl alcohol by the weight of cement.
