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.
