Problems solved by technology

[0002] At present, the existing foamed concrete blocks are all filled with benzene slabs in the concrete shell and cut into pieces. There is secondary processing during production, which causes waste of labor, energy and materials, and prolongs the construction period. Moreover, the concrete shell needs manual maintenance. Influenced by the weather, its mass is heavy, and the benzene board fills the gap between the cut blocks, and the bonding parts between the cut blocks are prone to cold bridges, resulting in indoor heat loss, condensed water, mold and moisture, and no contact with the building. In addition, the benzene board is easy to damage and pollute the environment, environmental protection energy, and resources, and its fire resistance is relatively low.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a self-insulating concrete block. Background technique [0002] At present, the existing foamed concrete blocks are all filled with benzene slabs in the concrete shell, and there is secondary processing during production, resulting in waste of labor, energy and materials, and prolonging the construction period. Due to the influence of the weather, its mass is heavy, and the benzene board fills the gaps between the cut pieces, and the bonding parts between the cut pieces are prone to cold bridges, resulting in indoor heat loss, condensed water, mold and moisture, and has no connection with the building. In addition, benzene panels are easy to damage and pollute the environment, environmental protection energy, and resources, and their fire resistance is relatively low. Contents of the invention [0003] In order to make up for the defects of the prior ar...
