Abstract

The process of maintaining the temperature and moisture conditions of concrete is termed as Curing. It is a must for the hydration reaction of concrete to occur which leads to its strength generation. Moisture, heat and time are the different components that constitute curing. Curing directly affects strength, re- sistance to freezing, abrasion and scaling resistance, chemical attack resistance etc. Different methods like shading, covering with gunny or hessian bags, mem- brane curing, and ponding method can be used for curing. In this paper we are using different colored polythene sheets (black, white, blue and pink) for curing. Compressive strengths and density are also compared with normal curing method. A total of 9 cubes are prepared for each type of colored paper curing. Three cubes are then tested at 7, 14 and 28 of curing for compressive strength. This study also identifies the best colored polythene sheet that can be used for curing.
