Fabricated type non-load-bearing cast-in-situ lightweight composite wall material

Abstract

The invention relates to a fabricated type non-load-bearing cast-in-situ lightweight composite wall material. The fabricated type non-load-bearing cast-in-situ lightweight composite wall material is prepared from the following raw materials in parts by weight: 19 to 43 parts of portland cement, 0.02 to 0.14 part of polypropylene, 0.08 to 0.192 part of a water reducing agent, 0.011 to 0.037 part of cellulose ether, 0.0098 to 0.022 part of sodium dodecyl sulfate, 9 to 20 parts of second-grade fly ash, 0.31 to 0.78 part of polyphenyl particles, 2.1 to 9.7 parts of yellow sand, 0.23 to 1.21 parts of a setting accelerator and 0.91 to 2.15 parts of an expansion agent. The wall prepared from the fabricated type non-load-bearing cast-in-situ lightweight composite wall material provided by the invention is improved in bearing capacity, and the problems of cracking, peeling and falling-off of the wall are avoided.

Description

technical field [0001] The invention belongs to a building material, in particular to an assembled non-load-bearing cast-in-place lightweight composite wall material. Background technique [0002] As the society pays more and more attention to the requirements of green energy conservation and environmental protection, the construction industry is also actively responding to the national call to save resources, reduce environmental pollution, and improve building materials to improve product quality and practicability. [0003] The existing wall materials are soft in texture, the moisture inside the wall materials is easy to evaporate, and shrinkage occurs, and the secondary hydration reaction during masonry is easy to cause cracking and peeling of the wall surface; and the existing wall materials are sound-proof and heat-insulating The performance is poor. The most important thing is that the walls made of these materials are not suitable for hanging heavy objects, and the p...
