Mechanical properties of self-curing concrete (SCUC)

According to lack of water, labor self curing concrete (SCUC) is necessary in construc- tion projects. In this study, it is focuses on concrete application with new admixture to achieve SCUC. The present study involves the use of shrinkage reducing admixture polyethylene glycol (PEG 400) in concrete which helps in self curing and helps in bet- ter hydration and hence strength. The effect of admixture (PEG 400) on water reten- tion, compressive strength, split tensile strength and modulus of rupture by varying the percentage of PEG by weight of cement from 0% to 1% were studied for M1 and M2 mixes. It was found that using PEG400 with dosage 0.3%, 0.5% gives an early strength to the concrete. It was also found that 0.5% of PEG 400 by weight of cement was the optimum for both M1 and M2 mixes.
