EXPERIMENTAL STUDY ON BEHAVIOUR OF CONCRETE USING SELF CURING AGENTS

Concrete is most widely used construction material due to its good compressive strength and durability. Depending upon the nature of work, the constituent materials; cement, fine aggregate, coarse aggregate and water are mixed in specific proportions to produce concrete. Concrete needs congenial atmosphere by providing moisture for a minimum period of 28 days for good hydratio n and to attain desired strength. Any laxity in curing will badly affect the strength and durability of concrete. Self - curing concrete is one of the special concretes in mitigating insufficient curing due to human negligence and inaccessibility of structur es in difficult terrains. It increases water retention capacity of mix. Many studies are done about the usage of Self curing concrete. In the present study, the effect of admixture, Poly Ethylene Glycol (PEG) & Super Absorbent Polymer (SAP) are studied wit h proportions of PEG 0 - 2% and SAP 0 - 0.4% in M25 grade of concr ete. Comparing both types of concrete with conventional concrete,the compressive, split tensile and flexural strength are found and optimum percentage of curing agent is determined .
