Lightweight clay bricks are made of sillimanite composite as the matrix, mixed with special additives and a small amount of rare earth oxides, and then high-pressure molding and high-temperature firing. Ordinary lightweight heat-insulating refractory bricks are clay, high-aluminum and high-strength floating bead bricks, low-iron mullite, high-aluminum poly-light heat-insulating refractory bricks, and diatomite heat-insulating refractory bricks.
Characteristics of lightweight clay bricks
4. Small shrinkage value: Due to the use of high-quality river sand and pulverized coal as siliceous materials, the shrinkage value is only 0.1-0.5mm/m, and the excellent materials with small shrinkage value ensure that your wall will not crack.
5. Impermeability: The pore structure of this product makes it poor capillary performance, slow water absorption and moisture conduction, and the time required for the same volume to absorb water to saturation is 5 times that of clay bricks.
6. Environmental protection: no pollution during manufacturing, transportation, and use, protection of arable land, energy saving and consumption reduction, it is a green building material.
7. Earthquake resistance: The use of lightweight bricks for the same building structure has an earthquake resistance level higher than that of clay bricks.
8. Durability: The long-term strength of aerated concrete is stable. After one year of exposure to the atmosphere of the specimen, the strength has increased by 25%, and it remains stable after ten years.
