1. The common point of ceramic permeable brick and terracotta brick is that they are fired at high temperature. However, the sintering temperature of terracotta bricks is 200 degrees Celsius lower than that of ceramic permeable bricks , so the bonding degree is weaker than that of ceramic permeable bricks , that is, the abrasion resistance is poor.
2. Clay brick is a combination of fine clay powder, so it has a larger surface area. The pores are small and impermeable during firing. The soil has the characteristics of water absorption, but because it is impervious to water, it cannot be penetrated (only by evaporation). Repeated damage to the particle binding site. The raw materials for ceramic permeable bricks can be porcelain, hard ceramics, high-quality concrete pellets, rubber particles, broken glass, etc. High-quality single-grain pellets can ensure that the permeable bricks have outstanding water permeability precursors, fine powder, mud Both sand and needles will greatly affect the water permeability, freeze-thaw resistance and service life of floor tiles.3. The terracotta brick peels after passing through one winter, that is, the capacity of the anti-ice water to swell can be weak. Ceramic permeable bricks have excellent resistance to freezing and thawing in the north because of the large inter-particle pores and the combination is sintering. It has dealt with the difficult problem that the cement permeable bricks with good water permeability are resistant to freezing and thawing, while those with good freezing and thawing resistance are impermeable.
