Curing is the most important part of concrete in construction. Nowadays there are much shortage of water in some areas, therefore curing cannot be done properly and also curing cannot be done properly in many cases due to inattention of human, inaccessibility of structure and areas, and some time due to presence of fluoride. There are two types of curing, first one is External Curing which is done by manually by human, and the second one is External Curing (Self-Curing) which is done by curing

... gent. Self-curing of concrete maintain the require moisture content and helps the concrete to obtain its strength and durability. Self-Curing method decrease the water evaporation, therefore water remains in the concrete as compared to conventional concrete. Specially for curing process nowadays water requires are 3m 3 in 1m 3 of concrete. Self-Curing admixture is much important and beneficial where water resource is insufficient. The admixture is a water soluble polymer. Fly ash improves concrete's workability, ultimate strength and durability as well as solves many problems. In this study polymer added with 0.5% and 1% by weight of cement and fly ash added with 20% by weight of cement.
