Calcium formate is used as a fast setting agent, lubricant and early strength agent for cement. It can also be used in concrete, dry mortar and tile adhesives to accelerate the hardening speed of cement and shorten the setting time, especially in winter construction, to avoid slow setting speed at low temperature and fast demoulding, so that the cement can be put into use as soon as possible. Depending on the amount of calcium formate, it can also strongly change the initial workability of wet mortar.

The amount of Calcium formate for dry mortar and concrete per ton is around 0.5~1.0%, and the maximum amount is 2.5%. The amount of calcium formate is gradually increased as the temperature drops. Even if the amount of 0.3-0.5% is applied in summer, it will have an obvious early-strength effect.
