Calcium formate is one of the soluble salts of formic acid. It has many similarities (properties and hazards) to other formates.
Calcium formate is a nonchloride accelerator used to accelerate the setting time of concrete. At equal concentration, calcium formate (Ca[OOOCH] 2) is less effective in accelerating the hydration of C3S than calcium chloride and a higher dosage is required to impart the same level of acceleration as that imparted by CaCl2 (Ramachandran ***4). An evaluation study of calcium formate as an accelerating admixture conducted by Gebler (***3) indicated that the composition of cement, in particular gypsum (SO3) content, had a major influence on the compressive strength development of concretes containing calcium formate. Results showed that the ratio of C3A to SO3 should be greater than 4 for calcium formate to be an effective accelerating admixture; And that the optimum amount of calcium formate to accelerate the concrete compressive strength appeared to be **3% by weight of cement. Calcium nitrate and calcium thiosulfate are also considered accelerators.
