Abstract

Abstract: The curing process for massive and inaccessible structures is troublesome. To overcome this difficulty and to reduce the evaporation by increasing the performance of mechanical properties, the process of internal curing is the superlative method. This research is aimed to investigate the mechanical and salt properties of Internal Cured Concrete prepared using Polyethylene Gylcol - 600. M25 grade concrete is prepared at various proportions of PEG viz., 0%, 0.5%, 1%, 1.5% and 2% by cement weight. The average maximum compression and flexural strengths were observed at 2% of PEG solution, while the maximum split tension strength was recorded at 1.5% of PEG. NaCl, KCl solutions are used to investigate the influence of salts. The specimens were prepared by utilising the mix that resulted the maximum compressive strength. The specimens are then immersed in both salts for 14 days and the results are evaluated. It was observed that, both the chemicals have shown hostile effect on concrete prepared using PEG-600 solution resulting in deterioration.
