Introduction of sodium silicate for waterproof concrete

Sodium silicate is an important inorganic salt with a wide range of uses. Among them, waterproof concrete is one of the important areas where sodium silicate is used. Sodium silicate in waterproof concrete can enhance the compactness and impermeability of concrete, improve the durability of concrete, and extend the service life of buildings. The effect, preparation methods and application fields of sodium silicate in waterproof concrete will be introduced and discuss the development prospects of sodium silicate in waterproof concrete will be discussed.

The role of sodium silicate in waterproof concrete

Enhance the compactness of concrete: Sodium silicate can react with cement to form calcium silicate gel, which blocks the pores in concrete and improves the compactness of concrete.

Improve the impermeability of concrete: Sodium silicate can react with cement hydration products to form solid crystals, block pores, reduce the permeability coefficient of concrete, and improve the impermeability of concrete.

Enhance the durability of concrete: Sodium silicate can react with cement hydration products to generate corrosion-resistant substances, improve the corrosion resistance of concrete and extend the service life of buildings.

Preparation method of sodium silicate for waterproof concrete

There are many methods for preparing sodium silicate, including the liquid phase method, gas phase method, solid phase method, etc. Among them, the liquid phase method is one of the most commonly used preparation methods. The liquid phase method is to mix quartz sand, soda ash, and water in a certain proportion, heat it to a certain temperature, and then evaporate and crystallize to obtain sodium silicate crystals. The advantages of the liquid phase method are a simple preparation process, low cost and large output, but the purity is relatively low. In order to improve the purity of sodium silicate, the preparation process can be improved, such as using high-purity raw materials and increasing the number of crystallization times.

Application fields of sodium silicate for waterproof concrete

Water conservancy projects: Sodium silicate for waterproof concrete can be used to make water conservancy facilities such as dams and canals to improve the anti-seepage performance and durability of the facilities.

Construction industry: Sodium silicate for waterproof concrete can be used to make basements, roofs and other parts of buildings to improve the waterproof performance and durability of buildings.

Underground facilities: Sodium silicate for waterproof concrete can be used to make waterproof layers for underground facilities such as subways and tunnels to improve the waterproof performance and durability of facilities.

Roads and bridges: Sodium silicate for waterproof concrete can be used to make waterproof layers for bridges, roads and other infrastructure to improve the impermeability and durability of the facilities.

Military facilities: Sodium silicate for waterproof concrete can be used to make waterproof layers for military facilities to improve the confidentiality and defense capabilities of the facilities.
