Abstract:- Conventionalconcrete require water curing for a minimum of 28 days to complete its targetstrength. Therefore water curing is very much necessary to preventunsatisfactory properties of cement concrete. In order to have good qualitycuring, surplus of evaporation from the surface need to be prevented.Self-curing concrete is one of the extraordinary concrete which is gainingimportance in recent days as it avoid errors which were caused by human,structures which are not available, terrains where curing becomes complicatedand in places where the fluoride content badly influences the property ofconcrete Plain concrete needs pleasant atmosphere by providing moisture for aminimum 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 moisturecontent. In the this research, the affect of admixture (SAP) on compressivestrength, by varying the percentage of SAP by weight of cement from 0%,0.8%,1.6%,2.4% & 3.2% are studied for M25 mixes
