Main characteristics of calcium formate early strength agent
Improve early strength. Calcium formate can significantly improve the early strength of concrete without adversely affecting the later strength.
Change the concrete's resistance to sulfate erosion.
Calcium formate is an organic early strength agent that will not corrode the steel bars in concrete.
Another function of it is to enhance the strength of cement. Cement admixtures can completely dry the water in cement, which greatly enhances the hardness of cement. Especially in winter, calcium formate has been widely used in engineering projects such as roads, bridges, and tunnels.
The specific role of calcium formate in concrete is as follows:
Improve strength and hardness. Calcium formate can promote the bonding between molecules in concrete, improve its strength and hardness, and at the same time control the shrinkage of concrete and extend the life of concrete.
Improve durability and reduce permeability.
Calcium formate fills the pores of concrete, reduces the intrusion of water and moisture, enhances the durability of concrete, and reduces permeability, making concrete more compact.
Improve fluidity and workability. By reducing the surface tension between concrete particles, calcium formate improves the fluidity of concrete, which is beneficial for processing and construction.
Early strength development. Calcium formate has a significant effect on improving the early strength of cement, especially for concrete constructed in winter or in low temperature and humid environments.
Delay setting time. Calcium formate, as a trace retarder, can delay the setting time of cement, reduce the amount of cement, and promote the crystallization of cement particles.
Calcium formate is a multi-effect concrete additive that can effectively improve the various properties of concrete, especially in strengthening early strength, improving durability and fluidity.
