Expanded clay aggregate (ECA) is a common building material, characterized by its light weight, high strength, and thermal insulation properties. It is primarily used for floor and ground filling in buildings. So, where is expanded clay aggregate produced? Details are as follows:
Where are building expanded clay aggregates produced?
There are many places where expanded clay aggregate (ECA) is produced, such as ECA manufacturers and building material companies, for example, Xi'an Baofengyuan ECA Building Materials Co., Ltd. For more details, we suggest you check relevant websites or consult relevant personnel.
What are the characteristics of building expanded clay aggregate?
1. Thermal insulation
Because of its porous structure, expanded clay aggregate has excellent thermal insulation properties. The thermal conductivity of concrete made with it is generally 0.3-0.8 W/(mK), which is 1-2 times lower than that of ordinary concrete.
2. High fire resistance
Its fire resistance is generally more than four times that of ordinary concrete. For the same fire resistance period, the thickness of ceramsite concrete slabs is 20% thinner than that of ordinary concrete. In addition, fly ash ceramsite can also be used to prepare refractory concrete with a fire resistance of up to 1200℃.
3. Good impermeability
Lightweight aggregate concrete exhibits superior impermeability compared to ordinary concrete. Taking 20MPa lightweight aggregate concrete and ordinary concrete as examples, after multiple tests, the impermeability index of ordinary concrete is B6, while that of lightweight aggregate concrete can reach B18-B25.
4. Good earthquake resistance
Lightweight aggregate concrete exhibits good seismic performance due to its light weight, low modulus of elasticity, and excellent resistance to deformation. Data shows that the damage rate of brick-concrete buildings reaches 40%-60%, the damage rate of frame-structured clay hollow brick buildings is 33%, while the damage rate of lightweight aggregate concrete buildings is only 5%. This clearly demonstrates the superior seismic performance of lightweight aggregate.
5. Highly adaptable
Concrete made with expanded clay aggregate is suitable for various building systems, such as frame-filled or self-supporting block buildings, one-mold-three-panel buildings, fully prefabricated large panels, internally cast and externally hung concrete, and fully cast slipform buildings.
