As a new type of early strength agent, calcium formate not only accelerates the hardening rate of cement, but also avoids the too slow setting rate in winter construction or under low temperature and humidity, it makes a great contribution to the early strength of the cement products to be put into use as soon as possible. For a long time, calcium chloride has been widely used in engineering, but it can corrode steel bar, chlorine-free coagulant has been developed at home and abroad, and calcium formate is a new type of early strength material, it can effectively accelerate the hydration of tricalcium silicate C3s in cement and increase the early strength of cement mortar, but it will not cause corrosion to steel bars and will not cause environmental pollution, therefore, it is also widely used in oil field drilling and cementing. Product characteristics: speed up the hardening of cement, shorten the construction period. Shorten the setting time, early molding. Improve the early strength of mortar at low temperature. Antifreeze and antirust. Chemical book technical properties and characteristics calcium formate is a white or grayish white crystalline powder. Under the standard curing condition, this product can make the concrete final setting within 4 hours. The strength of cast-in-place concrete can reach over 5MPA after 8 hours, and the cast-in-place concrete can be successfully demoulded. While ensuring the early strength of mortar and concrete, it can make the late strength of mortar and concrete increase normally and has no destructive effect on other technical properties of mortar and concrete.
