Development of Normal Strength and High Strength Self Curing Concrete and Self Compacting Concrete Using Sodium Polyacrylate As A Polymer

Abstract

The overall development of the country depends on infrastructure development for the uninterrupted progress of infrastructure availability of materials. In that materials water is the major material for the construction. Now a day’s need of water is very high and availability is less. For that reason we use the polymers in the place of water. The main objective of the present study is to investigate a suitable combination of compressive strength self-curing concrete and self-compacting concrete with two different curing techniques. Curing is the most important step in concrete construction lack of curing has significant impact on concrete strength and durability self curing concrete is designed to hold water and reduce water evaporation while increasing water retention capacity .Hydrophilic water soluble polymers can be used as self curing agents in concrete as they can absorb water and keep the surrounding medium moist so that water present in that can be medium used for reaction of cement self curing concrete is also ideal further in hot weather regions where large quantities of water are needed for curing. Self compacting concrete is a type of concrete that gets compacted under it self-weight. The use of self compacting concrete is spreading worldwide because of its very attractive properties in the fresh state as well as after hardening. The use of self curing concrete will lead to more industrialized production .It reduce the cost of concrete in constructions and improve the quality, durability and reliability of concrete structure and eliminate some of the potential for human error. The present investigation focuses on the compressive behavior of concrete with different proportions of polymers and compactions.
