The main types and the existing defects of the building blocks for the current building wall are as follows:

1) conventional (solid) blocks. The traditional solid building blocks mainly comprise concrete small building blocks and sintered hollow building blocks, and when the building blocks are built, the construction difficulty is high, the operation is slow, the influence of on-site wet operation on the environment is large, and materials are wasted. After the masonry is finished, the surface of the masonry is not flat, mortar needs to be painted on two sides, materials are consumed, and labor, construction period and quality are difficult to guarantee.

2) Traditional hollow blocks. The traditional hollow building blocks are mainly concrete small hollow building blocks, when the building blocks are built, the bonding area among the building blocks is not enough, and the integrity, the safety and the shock resistance of a wall body are poor.

3) Autoclaved aerated building blocks. The autoclaved aerated type building blocks are low in strength and high in water absorption rate, and when the mortar is painted, water in the mortar is quickly absorbed by the building blocks, so that the painted mortar can still crack, hollowly and delaminate in a large area even if reinforced by the steel wire mesh.

4) A light-weight lath. The production of the light batten mainly adopts a production process taking foamed cement as a main material, the batten has large size and high construction difficulty, the transportation and the installation are inconvenient, the water absorption rate of the foamed cement is high, the plastering mortar is difficult to form effective firm bonding with the (light) batten, the quality hidden troubles of cracking, hollowing, layering and even falling exist, and the investment in labor, materials, construction period and the like is large.

In addition, when the building blocks are applied to the household partition wall, the building blocks with the thickness of 200 mm can be selected, and the cavities (holes 6) in the building blocks are filled with thermal insulation mortar, so that the requirements of the household partition wall for thermal insulation, sound insulation, fire prevention and burglary prevention are met.

The type of the block: the main specifications of the building block are of four types according to different application positions, namely, the thicknesses of the building block are 100 mm, 120 mm, 150 mm and 200 mm. The wall with the thickness of 100 mm and 120 mm is mainly used for building walls of kitchens and toilets, 150 mm is mainly used for filling walls of bedrooms, and 200 mm is mainly used for filling walls of household partitions, external walls and public buildings.
