Description
Technical Field

Background
ALC (Autoclaved Lightweight Concrete ) wall is a prefabricated building material known for its light weight but high strength, and ALC wallboard has the advantages of light weight, good heat insulation, sound insulation, fire resistance, low moisture resistance, environmental protection in production process and materials, and is commonly used for exterior walls, interior partition walls, floors and roofs of various building types, including residential, commercial and industrial structures.
And ALC wall panels are a type of building material that belongs to the group of fabricated buildings, and are also characterized by light weight and easier installation, and ALC panels can be prefabricated in specific sizes and shapes, making them easy to install, and reducing construction time. While ALC (autoclaved lightweight concrete) wallboard has many advantages, there are also some disadvantages in strength and structure, disadvantages in strength:
(1) The tensile strength is relatively low, and the ALC wallboard is easy to crack when being subjected to tensile stress.
(2) The brittleness is larger, the ALC wallboard is relatively more brittle, and the ALC wallboard is easy to crack or fracture when being impacted or collided.
(3) Local load bearing capacity is limited, although ALC wall panels have a relatively high overall strength, they are relatively limited and require additional structural support in applications requiring high load bearing capacity.
Structural disadvantages:
(1) Special connectors and construction processes are required, and due to the characteristics of the ALC wall panels, specially designed connectors and construction methods are required for installation. This increases the complexity and cost of construction, requiring skilled workers to ensure quality of installation.
(2) Shrinkage and expansion ALC wall panels undergo some degree of shrinkage and expansion as the ambient humidity and temperature change. Such changes may lead to cracking of the wall or instability of the joint. The expansion joint is reserved or an elastic sealing material is used for alleviating the influence during construction.
(3) The surface treatment requirements are high-the surfaces of ALC wallboard often require secondary treatments, such as plastering or paint, to improve aesthetics and water resistance. This increases construction time and cost.
The construction method can further improve the convenient installation degree of the ALC wallboard, and further improve the strength of the ALC wallboard so as to reduce the load of a building, keep the stability of a frame of a high-rise building and not reduce the strength of a wall body, thereby realizing the effects of reducing the construction cost and enhancing the strength of the building, and being one of methods which need to be explored for the current construction industry to reduce the cost and improve the efficiency and sustainable development.
