Self-Curing of Concrete Incorporated with Polyethylene Glycol

Lalit Markam, Rahul Rathore

Abstract


Concrete is a combined mixture of cement, aggregates and water with or without suitable admixtures. Curing is the process of sustaining the proper moisture content to stimulate optimum cement hydration immediately after placement and to achieve desirable strength and other properties. In conventional curing of concrete, this is achieved by external supply of water after mixing, placing and finishing of concrete. In practice, the conventional type of curing is very difficult to perform as it shall need a large amount of water, meanwhile scarcity of potable water increases day by day. In order to save water as well as achieve curing, several researchers initiated the use of self-curing agents. Self-curing or internal curing is a technique that can be used to offer additional moisture in concrete for more effective hydration of cement and reduced self-desiccation. It can be achieved by using various reducing admixtures like polyethylene glycol. They provide sufficient moisture to the hydrating cement throughout the cross section of the concrete. This study deals with objective of gaining knowledge in the field of concrete technology which includes the study of selfcuring of concrete. The aim of the investigation is to evaluate the use of poly ethylene glycol as self-curing agent. Self-cured specimens were developed and kept as such without the application of any external curing.
