Self Cured concrete is a type of concrete with a special ability to reduce autogenous shrinkage responsible for early stage cracking. different type of internal curing agents are currently being used around the world. Using Self curing concrete will lead to an escalation in the Strength of concrete Self Curing is beneficial in low water cement ratio concrete because of the chemical shrinkage that accompanies Portland cement hydration and low permeability of these material. Since the water incorporated into and absorbed by the cement hydration products has a specific volume less than that of bulk water a hydrating cement paste will imbibe water from available source. while in higher water cement ratio concrete this water can be and often is supplied by external curing. The present work deal with the results of experimental investigation on Polyethylene glycol 400. Effect of these Admixture on various Strength of concrete are studied. Polyethylene glycol content varied from 1 to 3% by weight of cement. Various Strength are considered for investigation are Compressive Strength, Flexural Strength. Cube size 100mm for Compressive Strength, beam size 500x100x100mm for Flexural Strength were cast. all the specimen were Self Cured for 7 and 28 days and tested subsequently. The optimum measured quantity of PEG 400 for maximum Compressive and Flexural Strength was found 2 % for M60 grade concrete . Various microstructure crack appear in a low water content specimen while Self curing process to overcome this problem of cracking Glass fibers and Silica Fume are used. The Compressive and Flexural Strength are increased at 2% when comparison of conventional curing of concrete. Study recommended suitable PEG 400 as an internal Self curing agent as it was completely soluble in water.
