Foamed concrete for water plugging in mine

Grouting and blocking water is an important technology to prevent and control groundwater. At present, the main materials for blocking water are cement slurry and water glass slurry. The advantages are low cost and wide sources. However, it is easy to shrink after hardening, and a small gap will be produced. Rinse with water, the gap will become larger, so the effect is not ideal.
If we use foam concrete as a water blocking material, the effect will be much better. The foamed concrete does not shrink or deform, and the flow channel is increased to achieve a better water blocking effect.
We can provide high-performance foam concrete machine for filling in mine according to your different applications. For more information about our products, please contact us.

What is the service life of the CLC block as an insulating material?
The design life of a building is generally 50-100 years. Organic insulation materials are really not that durable. At present, the design life of organic thermal insulation materials is mostly 20-25 years. This means that the service life of this insulation material is not as long as that of buildings. In the entire life cycle of a building, 2-4 times of insulation construction are required, which will cause harm to the building.
The durability of foam concrete blocks exceeds 50 years and can be as long as a building. One-time construction can be used for life. In Northeast China, there are some thermal insulation projects from the 1950s. They have remained intact for more than 60 years. Under the premise of standard construction, with our higher performance foam concrete machine, the service life of CLC foam concrete blocks can reach 100 years.
