CALCIUM FORMATE
Calcium formate is a calcium salt of formic acid.
Calcium formate in the form of white crystalline powder (content > 98%) is moderately hygroscopic, bitter by taste, non-toxic, soluble in water.
Molecular formula: Ña(ÍÑÎÎ)2
Molecular weight: 130,116.
CAS No.: 544-17-2
Calcium formate accelerates the setting of cement mortars i.å. the transfer from liquid to solid state; increases the initial strength of the hardened mortar; quicken the hardening in terms of the attainment of the maximal strength by cement mortar; protects the concrete from freezing at low temperatures; ensures faster obtaining the designated shape for concrete and faster formwork removal.
