We all know that calcium formate is mainly used in construction, feed and other industries. When used as an early strength agent for dry-mixed mortar and concrete, it can increase the strength of cement. It can also be used for reinforced concrete. Calcium formate will not corrode the steel bars in concrete. The effect of initial setting can be achieved.

The raw materials for the production of calcium formate are formic acid and calcium carbonate. Therefore, the price of calcium formate will inevitably be affected by these two raw materials. The price of raw materials rises, and the price of calcium formate also rises accordingly. But if you can find a large manufacturer, they will have a large reserve of raw materials, and the price of calcium formate will be more stable.

Calcium formate can increase the early strength and release the mold quickly. It is suitable for construction mortar and various types of concrete, accelerates cement curing and shortens the setting time. Especially in winter construction, after adding calcium formate, the slow solidification of cement/mortar will return to normal at low temperature. Shorten the mold closing time of the prefabricated parts in the mold group, and quickly demould, so that the cement can be put into use faster.
Calcium formate dosage and precautions The dosage per ton of dry powder mortar and concrete is about 0.5~1.0%, and the maximum addition amount is 2.5%. The dosage of calcium formate gradually increases with the drop of temperature, even if the dosage of 0.3-0.5% is applied in summer, it will also have obvious early strength effect.
It is wise to choose a manufacturer for purchasing calcium formate. Hebei YIDA is a manufacturer of calcium formate, with 16 years of professional experience, it is a reliable and stable supplier.
