Abstract:

Numerous admixtures have reportedly been used with varying degrees of success to control damage to concretes and mortars subjected to freezing temperatures during placement. The most widely used admixtures for cold-eather concreting are calcium chloride CaCl2, sodium chloride NaCl, or a combination of these two materials. CaCl2 and NaCl appear to be more effective in combination than separately. The amount of CaCl2 and NaCl for successful cold-weather concreting increases as the temperature decreases below 0C. In European practice, quantities of chlorides up to a maximum of about 20 by weight of water are used, whereas in American practice the recommended maximum is 2 CaCl2 by weight of cement. Author
