The thickness of the composite material is 250mm, wherein the thickness of a reinforced concrete structure bearing layer is 150mm, the thickness of a rock wool heat-insulating layer is 50mm, and the thickness of a decorative surface layer is 50 mm. The external wall panel has higher surface density and lower installation efficiency, and is not beneficial to popularization and application.

Because the density of the surface of the external wall is high, a special crane is needed for installation, and the popularization and the application to the current building industrialization are not facilitated.
4. Concrete expanded perlite composite external wall panel

The thickness of the composite material is 300mm, wherein the thickness of the bearing layer is 150mm, the thickness of the heat insulation layer is 100mm, and the thickness of the decorative layer is 50 mm. The density of the surface of the external wall is high, and the external wall needs to be installed by a special crane, so that the popularization and the application of the current building industrialization are not facilitated.
5. Steel wire mesh cement heat-insulating material sandwich board
The steel wire net frame cement sandwich board is a semi-finished product which is made by welding low-carbon cold-drawn steel wires into a three-dimensional space net frame in a factory, filling a light heat-insulating core material (mainly a flame-retardant polystyrene foam board) in the middle, and spraying cement mortar on two sides of the sandwich board in a construction site or directly performing all prefabrication in the factory.

The wallboard has the advantages of good fire resistance, high porosity, good sound absorption performance of the material and the like, has popularization and application experience in developed countries in Europe and America for over fifty years, and is mature in process technology.

The assembled energy-saving composite wallboard is applied and popularized due to the excellent characteristics of the assembled energy-saving composite wallboard, particularly good heat insulation performance, but research results about the composite wallboard are not deep and comprehensive enough, and the following problems mainly exist:
1. the existing external wall has the defects of cracking, slipping, plane warping and the like caused by composite type, layered composite of different materials, multiple molding, multiple layers inside and outside, different materials, inconsistent temperature deformation, difference of physical properties and the like, so that rainwater erosion, freeze thawing, dropping and the like are caused.
2. Most of sandwich composite wallboards use common concrete as a structural layer and light aggregate concrete as a surface layer, relatively few researches are carried out, literature data of relevant researches on point support bending resistance and bearing performance of the relevant composite wallboards are lacked, and basic mechanical indexes of the structural layer required in the process of finishing basic installation and use of the wallboards are unclear.
3. The lightweight aggregate concrete has a certain heat preservation and insulation effect in the energy-saving composite wallboard, but the low heat conductivity of the lightweight aggregate is based on the premise of sacrificing the strength, so how to maintain the good heat preservation performance of the lightweight aggregate concrete material and further develop and improve the strength of the lightweight aggregate concrete becomes a subject to be researched and discussed.
