Effect of Mechanical Properties on PEG-400 as Partial Replacement of Cement for M-25 Concrete

Concrete is most widely used construction material due to its good compressive strength and durability. Concrete can be cured by water curing and by self curing agent. Conventional concrete require water curing for a minimum of 28 days to complete its target strength. Self-curing concrete is one of the extraordinary concrete which is gaining importance in recent days as it avoid errors which were caused by human, structures which are not available, terrains where curing becomes complicated and in places where the fluoride content badly influences the property of concrete Plain concrete needs pleasant atmosphere by providing moisture for a minimum period of 28 days for good hydration and to attain desired strength. Self curing concrete is the one which can cure itself by retaining its moisture content. In the this research, the affect of admixture (PEG-400) on compressive strength, by varying the percentage of PEG-400 by weight of cement from 0% ,0.9%,1.8%,2.7% & 3.6% are studied for M25 mixes.
