The American Society of Concrete Contractors has published Position Statement No. 31, “Acceptable Use of Calcium Chloride in Concrete.”
The paper states that, while many specifications prohibit its use, the use of calcium chloride as an accelerating admixture can be acceptable, economical and beneficial to owners under certain conditions. It can be particularly useful when placing flatwork in cold weather.
The calcium chloride document is the latest in a series of papers on key issues of interest to cast-in-place concrete contractors, architects and engineers.
