The manufacturer tells you using calcium formate skillfully to solve the problem of setting and hardening of cement
The early strength growth of cement is fast, and the later strength growth is slow. If the temperature and humidity are suitable, its strength can still increase slowly after several years or more than ten years. We will talk about clever use of calcium formate to solve the problem of setting and hardening of cement. Setting time is one of the important performance indexes of cement (1) The hydration of cement progresses from the surface to the inside gradually. With the continuation of time, the degree of hydration of cement is continuously increasing, and the hydration products are also continuously increasing and filling the capillary pores, so that the porosity of the capillary pores decreases and the porosity of the gel pores increases accordingly. Calcium formate can increase the concentration of Ca 2+ in the liquid phase and accelerate the dissolution rate of calcium silicate. And the effect of the same ion will accelerate the crystallization, increase the solid proportio
