Calcium formate is an organic substance with the molecular formula C2H2O4Ca, used as a feed additive, is suitable for all kinds of animals, has acidification, anti-mildew, antibacterial and other effects, and is used in industry as a rapid coagulant, lubricant, and early strength agent for cement. It is used in construction mortar and various concretes to speed up the hardening speed of cement and shorten the setting time, especially in winter construction, to avoid slow setting speed at low temperatures. Fast demolding, so that the cement can improve its strength as soon as possible and put it into use. Calcium formate uses: all kinds of dry-mix mortars, all kinds of concrete, wear-resistant materials, flooring industry, feed industry, tanning. Calcium formate participation dosage and precautions The dosage of dry mortar and concrete per ton is about 0.5~1.0%, and the maximum addition is 2.5%. The amount of calcium formate is gradually increased with the drop of temperature, and even if the amount of 0.3-0.5% is applied in summer, it will have a significant early strengthening effect.
