Embodiment Construction

[0022] specific implementation plan

[0023] Combined with the flow chart, the present invention uses calcium carbide slag refined crystalline lime to partially replace unslaked lime to prepare autoclaved aerated block material and its method, and the production operation is carried out according to the following process steps:

[0024] 1. Material selection: The moisture content of refined crystal lime with carbide slag is 30.0% by mass, the mass percentage of calcium hydroxide is 66.0%, and the mass percentage of calcium oxide in quicklime is 82.0%; the mass percentage of silicon dioxide in fly ash The percentage content is 61.0%, the mass percentage content of alumina is 27.5%, the mass percentage content of calcium oxide is 4.5%, the mass percentage content of iron oxide is 3.0%; ordinary portland cement.

[0025]2. Add fly ash and water into a ball mill for wet grinding in a mass percentage of fly ash: water at a ratio of 57:43, control the particle fineness, and more tha...

Abstract

The invention relates to a refining electric stone ballast that is the preparation of autoclaved and aerated block material by using crystal lime parts to substitute quick lime parts and a method thereof; wherein, siliceous material pulp is obtained by wet grinding the mixture of material with silicon and water; siliceous mixing material pulp is obtained by adding additive agent and cement into the material pulp, which are mixed for 2.0 to 10.0 minutes and heated to 40.0 to 45.0 DEG C; crystal lime and quick lime are added into the siliceous material pulp and are mixed; gas former is then added and mixed for 30.0 to 50.0 seconds; steam aerated block casting material pulp is obtained and is gas emitted, statically stopped, cut, autoclaved and formed. By adopting the direct adoption electric stone ballast of crystal lime, calcium carbonate, unburned carbon and other impurities are decreased, and the quality of autoclaved and aerated block is improved; by first adopting wet grinding siliceous material and then adding electric stone ballast cement process, parts of quick cement can be substituted markedly and production cost can be reduced; the autoclaved and aerated block prepared by the technique is energy-saving, light in quality, and high in strength.

Description

technical field [0001] The invention relates to a method for preparing an autoclaved aerated block material by partially replacing quicklime with refined carbide slag, namely crystalline lime, and belongs to the field of inorganic chemical industry or silicate building materials. Through the method, on the one hand, the present invention can comprehensively utilize industrial waste residues from thermal power plants and polyvinyl chloride plants, control pollution, and protect the environment; on the other hand, it can turn waste into wealth, realize resource recycling, and obtain huge economic benefits. technical background [0002] The deepening of the concept of circular economy has brought a new spring to the waste recycling industry. Circular economy is the use of ecological laws to guide the economic activities of human society. It is centered on low consumption, high-efficiency utilization and recycling of resources. development benefits. There are three principles ...
