Firebrick dust-containing aerated building block and making method thereof

Abstract

The invention discloses a firebrick dust-containing aerated building block and a making method thereof. The aerated building block is made from, by weight, 12-23 parts of silicon-calcium slag, 24-37 parts of firebrick dusts, 26-39 parts of Portland cement, 19-35 parts of gangue, 14-26 parts of anorthite, 18-32 parts of porous ceramsite, 28-42 parts of flue dust, 6-12 parts of locust bean gum, 10-15 parts of boron slag, 16-28 parts of blast furnace water quenching slag, 4-8 parts of sodium tripolyphosphate, 3-4 parts of silicon-aluminum alloy powder, 1-2 parts of sodium peroxide and a proper amount of water. The firebrick dusts added in the invention cooperate with gangue, anorthite and silicon-calcium slag to improve the mechanical performances, the acid and alkali corrosion resistance and the weatherability of the aerated building block, and cooperate with the porous ceramsite, the boron slag and the blast furnace water quenching slag to improve the fire resistance and the heat insulation property of the aerated building block. The aerated building block made in the invention has the advantages of excellent comprehensive performances, excellent mechanical performances, excellent weatherability, excellent acid and alkali corrosion resistance, excellent ageing crack resistance, excellent heat insulation property and excellent fire resistance.

Description

technical field [0001] The invention relates to an aerated block added with refractory brick slag and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Aerated block is a new type of wall material that saves energy, saves soil, and makes use of waste. It is widely used in various civil and public buildings because of its advantages such as the usable area of ​​buildings. With the rapid development of my country's construction industry and the continuous improvement of people's living standards, the performance requirements for aerated blocks are getting higher and higher. However, the comprehensive performance of traditional aerated blocks is increasingly unable to meet market demand. Therefore, there is an urgent need for To develop an aerated block with excellent comprehensive performance. Contents of the invention [0003] The object of the present invention is to provide an aerated block added with refractory bri...
