Concrete brick is a solid brick or porous semi-blind brick made of cement as the binder material and sand, stone, etc. as the main aggregates, mixing with water, molding, and maintenance. Concrete bricks have the characteristics of light weight, fire prevention, sound insulation, heat preservation, seepage resistance, earthquake resistance, durability, etc., and non-polluting, energy saving and consumption reduction, can be used directly to replace the sintered ordinary bricks, porous bricks for a variety of load-bearing building wall structure, is an important part of the new wall materials
