Most authoritative works that discuss the issue of whether or not calcium chloride should be used as an accelerating admixture in concrete made with Type V sulfate-resisting cement warn against its use. The origin of this warning is reviewed, and the conclusion is reached that it is probably not harmful to obtaining the desired level of sulfate resistance (for which the use of Type V cement was specified) to use calcium chloride in normally acceptable amounts as an accelerating admixture in such concrete to mitigate the effects of cold weather.
