Introduction to the role and application of lithium silicate in cement

lithium metasilicate is a colorless, tasteless, non-toxic and odorless solid with good chemical and thermal stability. Concrete using lithium silicate as an additive is widely used in engineering structures to enhance concrete strength, improve concrete properties, and improve durability.

The role of Silicic acid in cement

1. Promote the hardening and strength formation of concrete

Adding an appropriate amount of lithium silicate can promote the hardening and strength formation of cement and increase the compressive and flexural strength of concrete. The mechanism of action of lithium silicate in cement is to accelerate the initial reaction of cement, form more hydration products and gels, and improve the strength and durability of concrete.

2. Improve the durability of concrete

The durability of concrete is mainly affected by its microstructure and physical properties. Lithium silicate can improve the physical properties of concrete, enhance the stability of the microstructure, and increase the durability of concrete.

3. Reduce cement usage

Adding an appropriate amount of silicic acid (h2sio3) to concrete can reduce the use of cement and reduce the production cost of concrete. silicic acid (h2sio3) can speed up the cement reaction rate, shorten the age, and reduce the loss of cement strength during the same age, thereby reducing the amount of cement.
