Abstract
Curing of concrete is the process of maintaining satisfactory moisture content in concrete during its early stages in order to develop the desired properties. However good curing is not always practical in many cases. The present study deals with the effect of polyethylene glycol and poly-vinyl alcohol (PVA) on concrete and their contribution to strength which are carried out. The effect of admixtures in mechanical characteristic of concrete i.e., compressive strength, split tensile strength and flexural strength by varying the percentage of PEG-200, PEG-400, PEG-600 from 0% to 1.5% by weight of cement is studied for M30 grade of concrete and the optimum percentage of PEG in self curing concrete with conventional concrete with water curing is compared. The optimum percentage with PEG is coated with PVA and strength analysis is done. From the results it is analyzed that adding of PEG 600 will give more strength compared to PEG 200 , PEG 400 and it is also observed that Coating of PVA made a very less impact in the strength of concrete.
