Problems solved by technology

For example, hollow blocks need to be sintered, which consumes a lot of energy, pollutes the environment, and takes a long time to make; gypsum hollow slats have poor waterproof performance and low fire resistance; polystyrene foam sandwich panels are heavy and low in fire resistance, and polystyrene will be released when burning. Poisonous ethylene gas; GRC hollow slats have low surface strength and great damage during transportation; magnesium chloride cement plant fiber hollow slats are mainly made of magnesium oxide and magnesium chloride, which have high early strength but insufficient later strength, poor water resistance and large deformation. When the climate is humid, there will be a phenomenon of re-halogenation, which will affect the quality and appearance of the product

Abstract

A dual-layer sandwich-type solid wall slab is composed of two surficial thin cement slabs and a foam concrete core layer. It is proportionally made of fast hardening sulphoaluminate cement, powdered coal ash, river sand, fibers, hydrogen peroxide as foaming agent, and stabilizer. Its advantages are light weight, high surface strength and high insulating effect.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a concrete product. Background technique [0002] With the development of urban buildings and the continuous improvement of building functions, people have put forward new requirements for wall materials such as light weight, environmental protection, energy saving, thermal insulation, sound insulation, and fire prevention. The traditional wall materials made of clay as the main raw material and produced by the sintering process have been gradually eliminated, replaced by a wide variety of lightweight and environmentally friendly wall materials, such as hollow blocks, gypsum hollow slats, and polystyrene foam sandwich panels. , GRC hollow slats, fly ash hollow slats, magnesium chloride cement plant fiber hollow slats, autoclaved aerated concrete slabs, etc. Although the above-mentioned light wall materials have their own strengths, they all have some shortc...
