Calcium formate is an early strength agent that accelerates the setting and hardening of concrete / mortar

Calcium Formate is a white crystal with excellent fluidity. It is used as an early strength agent in mortar. In dry-mixed mortar products, such as insulation mortar, tile adhesive, cement-based plastering mortar, repair mortar, etc., in order to improve their early strength, high-aluminum cement and gypsum are usually added as set accelerators in low temperature environments. It is also necessary to add an antifreeze for antifreeze. Calcium formate has a dual role as a new type of early strength agent. It can not only accelerate the hardening speed of the cement, improve early strength, but also avoid the slow setting of the mortar during winter construction or low temperature and humidity, making the mortar The product can be put into use as soon as possible, especially for early strength.
I. Product Features:
Calcium formate is an early strength agent that accelerates the setting and hardening of concrete / mortar. Accelerated concrete / mortar setting and hardening are:
1. Reduce initial setting time
2. Normally change the retardation of cement / mortar under low temperature conditions.
3. Increase the early strength growth rate.
4. Shorten the mold closing time in the module in the production of concrete precast parts.
5. Shorten the time for concrete to reach the load capacity.
Second, the amount added
The dose rate depends on the formulation design, process, type of material and expected effect, but usually:
500 g-2000 g per 100 kg of cement
A preliminary test is recommended to determine the correct addition for the application.
3. Scope of application
Calcium formate can be used in concrete, dry-mix mortar and tile adhesives, etc. It acts by setting and hardening time by accelerating the formation of tricalcium silicate.
