Effect of Calcium Chloride on the Properties of Concrete and Mortar

摘要

Specifications for using calcium chloride in concrete and mortar provide that calcium chloride should be used in small amount expressed as percent weight of cement to get an early age strength development. This effect is more visible when it is used with a mixing and curing temperature below 70F. This study was taken up to find out experimentally the optimum percentage of calcium chloride which can give early strength development generally in hot weather and also to find out its effect on setting time, rate of strength development of concrete and mortar as well as its effect on corrosion of steel and shrinkage.
