Used as fast setting agent, lubricant and early strength agent for cement. It is used in building mortar and various concretes to accelerate the hardening speed of cement and shorten the setting time, especially in winter construction to avoid the setting speed being too slow at low temperature. Fast demolding, so that the cement can be put into use as soon as possible. Calcium formate uses: all kinds of dry-mixed mortar, all kinds of concrete, wear-resistant materials, flooring industry, feed industry, tanning. Calcium formate participation and precautions The amount of calcium formate per ton of dry mortar and concrete is about 0.5 ~ 1.0%, and the maximum amount is 2.5%. The amount of calcium formate is gradually increased as the temperature decreases. Even if the amount of 0.3-0.5% is applied in summer, it will have a noticeable early strength effect.
