EXPERIMENTAL INVESTIGATION ON MECHANICAL PROPERTIES OF SELF CURING CONCRETE WITH SILICA FUME USING SODIUM POLYARCYLATE AND PEG 6000

Now a day's construction field is witnessing lot of crisis, one of them is water scarcity. Nearly one third of water is required for construction. To overcome this crisis, self curing agents are introduced and used. This paper investigates the strength characteristics of self curing concrete with silica fume incorporating different chemical curing agents for eliminating the shrinkage effect. The selected grade of concrete was M30. The self curing agents were polyethylene glycol-6000 (0.2%, 0.3% and 0.4%) and Sodium polyacrylate (0.2%, 0.3% and 0.4%) related to the cement mass. Partial replacement of cement with silica fumes (5% and 10%) to increase the properties of the concrete. The optimum mix ratio was taken for the casting of RC beam and the strength characteristics were studied and compared with the control mix. The effect of variation in strength parameters and autogenous shrinkage i.e., (Compressive, split tensile and flexural strength) were analysed for different dosage of self curing agent.
