If the boring person is poor, it means that the brick has heavy skin or Crack phenomenon, heavy skin is the formation of the brick, the material in the air is not discharged, resulting in poor bonding between materials and materials, internal cracks, can not be seen from the surface, only to listen to sound to identify. The fifth point: Seeing the dimensions and checking them one by one, products with a size error of more than 0.5 MM and a flatness of more than 0.1 MM will not only increase the difficulty of construction, but also have a poor effect after renovation, and cannot be used for projects.
