Abstract

The invention relates to autoclaved light sand aerated concrete blocks. The autoclaved light sand aerated concrete blocks are prepared from water and a main material at a ratio of 0.6 to 0.8; the main material is prepared from, by weight, 64 to 78% of saw mud, 3 to 6% of desulfurized gypsum, 10 to 18% of quick lime, 8 to 14% of cement, and 0.4 to 0.7% of aluminium powder. A preparation method comprises following steps: quick lime and desulfurized gypsum are smashed, and are subjected to ball milling; saw mud is grinded; steel bar is subjected to treatment; an obtained material slurry, a cementing agent, and cement are stirred at a certain ratio; after pouring, moulds are delivered to a standing area for aeration and prehardening; an obtained product is subjecting to cutting; obtained green bodies are delivered into a still kettle for maintenance, and are subjected to separation, packaging, and conveying; and generated wastewater and waste materials are recycled. Beneficial effects of the autoclaved light sand aerated concrete blocks are that: thermal insulation properties are excellent; permeability resistance is excellent; shrinkage value is lower; the autoclaved light sand aerated concrete blocks are green and friendly to the environment, are safer, are excellent in sound insulation effect and machinability, and are economical.

Description

technical field

[0001] The invention relates to an autoclaved light sand aerated concrete block and its production process, in particular to an autoclaved light sand aerated concrete block with saw mud as the main material and its production process. Background technique

[0002] Autoclaved aerated concrete blocks are made by adding aluminum powder to the ingredients of calcareous and siliceous materials as an air-entraining agent, adding water to stir, pouring into shape, gas expansion, pre-curing and cutting, and then cured by high-pressure steam Porous silicate blocks.

[0003] The stone processing industry in Baishi Town, Wenshang County is well developed. Processing stone will produce a large amount of sawing mud. The sawing mud floating in the air will easily cause great harm to the human respiratory tract; in heavy rain, the sawing mud will flow into the field with rainwater, which will easily cause crop production reduction. It is even urgent to solve the pollution ...
