How are shale porous bricks and clay porous bricks distinguished?
Dimensional deviation is less than clay brickBecause the plastic index is better than that of clay shale itself, although the requirements of the national standard for the size deviation of sintered brick is the same, but the size deviation of shale in actual production is generally less than the clay brick.
Weathering resistance is better than clay brickDue to differences in clay shale and its performance, the national standard requires shale weathering properties than clay bricks.
