Abstract
The invention provides an aerated concrete block. The aerated concrete block is prepared from the following components in parts by weight: 100 to 120 parts of cement, 15 to 20 parts of coal ash, 0.1 to 0.3 part of aluminum powder, 2 to 3 parts of silica sand and 5 to 8 parts of furnace slag, and the ratio of water to materials is 0.6 to 0.65. The aerated concrete block provided by the invention is excellent in heat preservation and heat insulation performances, and the heat conductivity coefficient is between 0.12 w/(m.k) and 0.14 w/(m.k).
Description
Technical field
The present invention relates to a kind of air-entrained concrete building block.
Background technology
China " 12 " planning is clearly proposed in terms of construction material：" increase quality product energetically, exploitation and popularization are new
The requirement of type building material product ".Aerated concrete products exist as main novel wall material, the exploitation upgrading along with product
Meet materials for wall complex function aspect and shown great advantage, market demand just increases year by year, and application prospect is non-
Chang Leguan.
The content of the invention
The invention provides a kind of air-entrained concrete building block.
The present invention provides a kind of air-entrained concrete building block, the air-entrained concrete building block by following mass fraction each component
Composition：Cement 100-120 parts, flyash 15-20 parts, aluminium powder 0.1-0.3 parts, silica sand 2-3 parts, slag 5-8 parts；Ratio of water to material is
0.6-0.65。
Preferably, the air-entrained concrete building block is grouped into by each group of following mass fraction：110 parts of cement, fine coal
18 parts of ash, 0.2 part of aluminium powder, 2.5 parts of silica sand, 6 parts of slag；Ratio of water to material is 0.62.
The present invention also provides the preparation method of above-mentioned air-entrained concrete building block, first mixes in the cement of formula ratio, water, flyash
Stir after conjunction, add remaining component of formula ratio, stir, pulp is to finished product.
The present invention is optimized to the proportioning between raw material composition and each raw material, and the air entrained concrete for preparing is built
The insulation of block, heat-proof quality are excellent, and thermal conductivity factor is between 0.12-0.14w/ (mk).
