Industrial Grade Concrete Additive Calcium Formate for Cement

详情

1. Concrete Additive. Calcium formate is used as a fast setting agent, lubricant and early strength agent for cement. It can be used in construction mortar and various concretes to accelerate the hardening speed of cement and shorten the setting time. Especially in the winter construction, adding calcium formate to the cement can prevent the setting speed from being too slow at low temperature. The demoulding is fast, so that the cement can be put into use as soon as possible to increase its strength. Dosage of calcium formate and precautions: The amount of dry mortar and concrete per ton is about 0.5~1.0%, and the maximum addition amount is 2.5%. The amount of calcium formate is gradually increased as the temperature drops. Even if the amount of 0.**0.5% is applied in summer, it will have an obvious early-strength effect.
