Calcium formate is a new low temperature early strength coagulant, for cement calcium formate can significantly improve the early strength, shorten the setting time, widely used in mortar (tile adhesive, cement-based plastering mortar, repair mortar, waterproof mortar) and concrete industries.
Calcium formate can accelerate the cement hardening speed, catch high early strength, and avoid the problem of setting speed is too slow in winter or low temperature wet conditions, so that cement products as soon as possible to improve the strength into use, calcium formate contributes to the early strength.
In summer, the dosage of calcium formate is usually 0.3%~ 0.7% of cement. In winter, the dosage of calcium formate should increase with the decrease of temperature, generally 0.5 %~ 1%, and the highest should not exceed 2.5 %. In view of the characteristics of cement used in dry mortar with low strength in early stage and high strength in late stage, calcium formate should be added in the product. It is beneficial to increase the early intensity.
The calcium formate produced by our company has good fluidity, quick dissolution and compound function of reducing water and engendering air, which can improve workability of mortar and increase durability.
