Problems solved by technology

Lightweight concrete wall panels generally include prefabricated and cast-in-place. Prefabricated lightweight concrete wall panels are produced in a factory and assembled on site. The production process is relatively complicated, and the requirements for production equipment are high. It is easy to cause cracks in the board joints, causing water seepage, which affects the quality and life of the building. The connection between the prefabricated wall panels and the load-bearing components is relatively complicated. The board itself is prone to cracking and deformation, and the joint between the wall board and the load-bearing member is prone to cracks, resulting in water seepage, and the external insulation layer is not easy to install

Abstract

A light concrete wall slab cast in-situ is composed of main body and welded reinforcing steel bar net in said main body. Said main body is made up of water, cement, powdered coal ash, slag powder, silicon powder, efficient composite water-reducing agent, polypropylene fibres, glass fibre fabric or alkali-resistant plastic-coated glass staple, modified cement polymer emulsion (or powder), haydite, and sand. Its advantages are light weight, high strength, low shrinkage, not deforming and cracking, and low cost.

Description

technical field [0001] The invention relates to a building material, in particular to a cast-in-place lightweight thin-layer concrete wall board. Background technique [0002] In recent years, because clay solid bricks have been banned and gradually eliminated, many new types of building wall materials have emerged, especially the application of lightweight concrete is being promoted. Lightweight concrete wall panels generally include prefabricated and cast-in-place. Prefabricated lightweight concrete wall panels are produced in a factory and assembled on site. The production process is relatively complicated, and the requirements for production equipment are high. It is easy to cause cracks in the board joints, causing water seepage, which affects the quality and life of the building. The connection between the prefabricated wall panels and the load-bearing components is relatively complicated. The board itself is prone to cracking and deformation, and the joint between th...
