A method for producing lightweight new wall material by mixing coal slag

Abstract

The invention discloses a method for producing a novel light-weight wall material by mixing coal slag. The coal slag produced by a thermal power plant replaces 20-100% of sand. On the one hand, the consumption of the sand is reduced, the production cost is lowered greatly, resources are saved, waste materials are recycled, and the environmental pollution is relieved. On the other hand, early hydration heat of concrete mixed with the coal slag is reduced, the sulfate resistance of the concrete is improved, and the impermeability has the direct bearing on the carbonization resistance, freezing resistance and erosion resistance of the concrete and further has an important effect on shrinkage and creepage of the concrete. In addition, the coal slag is lighter than the sand, so that the volumetric weight of the concrete mixed with the coal slag is reduced; a wall is light in deadweight; the mounting efficiency is improved; for mechanical properties, compression resistance and a suspension force of the light-weight wall material mixed with the coal slag are greatly higher than those of a light-weight wall material used for construction and produced by mixing no coal slag; and the method has very good economic and social benefits.

Description

technical field

[0001] The invention relates to a novel inorganic non-metallic material manufacturing technology, in particular to a method for producing a new lightweight wall material by mixing coal slag. Background technique

[0002] In recent years, with the emerging of the real estate industry, the development of the construction industry is also changing with each passing day, so the requirements for building materials are getting higher and higher. For producers, improving quality and controlling costs are two necessary considerations. Factors, the light wall materials for construction currently produced are generally made of cementitious materials, sand, water, water reducing agents, foaming agents, ceramsite, etc. Among them, the cementitious material generally adopts all-cement above grade 42.5, and after the production is completed, it is formed by steam curing. The production cost of one-time investment is relatively high, which affects the development and promot...
