Calcium formate as a new type of early-strength agent has a dual role, not only to accelerate the hardening speed of cement to improve the early strength, but also to avoid the construction in the winter or low-temperature humidity, the speed of solidification is too slow, so that the cement products as early as possible to improve the strength of the put into use, especially for the early strength of the larger contribution.

Calcium formate is a new type of early-strength materials, can effectively accelerate the hydration of cement tricalcium silicate C3S, increase the early strength of cement mortar, but will not cause corrosion of steel and other corrosion will not cause pollution to the environment, so in the oilfield drilling and cementing also have a wide range of use.

Calcium formate product properties accelerate the hardening speed of cement and shorten the working period. Shorten setting time and early molding. Improve the early strength of mortar at low temperature. Anti-freezing and rust-blocking.

Calcium formate is white or off-white crystalline powder. Under the standard condition of curing, this product can make the concrete final set in 4 hours. 8 hours or so can make its strength reach more than 5Mpa, which can make the cast-in-place concrete smooth demolding. While ensuring the early strength of mortar and concrete, it can make the late strength of mortar and concrete grow normally, and it has no destructive effect on other technical properties of mortar and concrete. Scope of application: It is used in tile binder, cement-based plaster mortar, repair mortar, waterproof mortar, heat preservation mortar, wear-resistant flooring and putty, etc. It can improve the denseness and prolong the opening time of the product. The dosage of calcium formate is generally not more than 1.2% of the total amount of mortar. Calcium formate is not incompatible with other additives, it can be mixed with cement, sand and other additives in the mixer according to a certain proportion.
