Appearance quality requirements should be basically the same for the color tone pattern of the same batch of blocks; the appearance quality grades such as corners, ribs and cracks of the blocks should meet the requirements of Table 4.25.6. Physical performance requirements: bulk density is not less than 2.6g/cm3; water absorption is not more than 0.75%; dry compressive strength is not less than 20MPa; bending strength is not less than 7.0MPa.
