2. Melting Ice Its ability to melt ice is a result of the high degree of heat produced during its dissolution. Calcium chloride is far less corrosive and move effective than rock salt, meaning that it can help significantly reduce equipment maintenance costs and even

Calcium Chloride - an overview | ScienceDirect Topics

Calcium formate acts in a manner similar to calcium chloride, but high dosages are required and its solubility is considerably less (approximately 17 g/100 g compared with 75 g/100 g at 20 C). Two or more chemicals are often used in coination to increase the concentration and improve the performance of liquid admixtures, which are preferred to powders for accurate dosing of concrete.
