Now a day’s construction field facing many problems, one of them is scarcity of water. Proper curing is not practically possible in most of the cases. So, the concept self curing distributes the extra curing water (uniformly) throughout the entire 3-D concrete microstructure. Self curing agent is more readily available to maintain the saturation of the cement paste during hydration and reducing the autogenous shrinkage. The aim of the project is to investigate the strength characteristics i.e compressive strength, split tensile strength and flexural strength of self curing concrete with silica fume using sodium polyacrylate and to eliminate the shrinkage effect. The grade of the concrete selected was M30. Self curing agent used is sodium polyacrylate (0.2, 0.3% and 0.4%) relative to cement mass. Partial replacement of cement with silica fumes 10% to increase the pozzolanic properties of the concrete. The optimum mix ratio is taken for the casting of beam and the flexural strength characteristics was studied and compared with the control mix.
