| Abstract | ||||
| According to lack of water, labor self curing concrete (SCC) is Necessary in construction projects. In this study it was focus on concrete application with new admixture to achieve SCC. The present study involves the use of shrinkage reducing admixture polyethylene glycol (PEG 400) in concrete which helps in self curing and better hydration and hence strength gain. The affect of admixture (PEG 400) on water retention, 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 PEG 400 could help in achieving self curing by giving strength on par with conventional curing. It was also found that 0.5% of PEG 400 by weight of cement was the optimum for both M1 and M2 mixes. | ||||
