Abstract
The invention provides an aerated concrete building block. The aerated concrete building block comprises following materials by weight: 70-72% of coal ash, 15-18% of lime, 2-3% of flue gas desulfurization gypsum, 10-12% of cement, and 0.08-0.1% of aluminum paste, with the ratio of water to materials being 0.6-0.65. A preparation method is also provided. The flue gas desulfurization gypsum is adopted to replace natural gypsum, thus solving problems that the natural gypsum namely the adjusting material used in production processes of aerated concrete building blocks is not easily available and the purchasing cost is high. Industrial waste materials are utilized, thus achieving cyclic economy. The cost of the raw materials is low, thus reducing the product cost.
Description
Technical field
The present invention relates to a kind of air-entrained concrete building block.
Background technology
China " 12 " planning clearly proposes aspect material of construction: the requirement of " increasing energetically quality products, exploitation and popularization building material product ".Aerated concrete products is as main novel wall material, and the exploitation upgrading that is accompanied by product has shown great advantage meeting aspect materials for wall complex function, and market demand increases just year by year, and application prospect is very optimistic.But the main adjusting material in existing aerated concrete products production process is the plaster of paris, still, the plaster of paris is subject to the impact in output and market, and its market demand has been that supply falls short of demand; Meanwhile, China's desulfurated plaster quantity discharged has exceeded 100,000,000 tons at present, and rises year by year, to its mishandling secondary pollution that will cause environment.
Desulfurated plaster is the same with plaster of paris composition, is even better than the plaster of paris; Based on above factor, the applicant, by desulfurated plaster being replaced to the technical study of the plaster of paris, has invented the air-entrained concrete building block that a kind of desulfurated plaster replaces the plaster of paris to produce.
Summary of the invention
The invention provides a kind of air-entrained concrete building block, raw material adopts desulfurated plaster to replace the plaster of paris, thereby solves the difficult buying of the adjusting material plaster of paris used in existing air-entrained concrete building block production process, the problem that purchase cost is high.
The invention provides a kind of air-entrained concrete building block, the material in described air-entrained concrete building block is made up of each component of following mass percent: flyash 70%-72%, lime 15%-18%, desulfurated plaster 2%-3%, cement 10%-12%, aluminium cream 0.08%-0.1%; Ratio of water to material is 0.6-0.65.
The present invention also provides the preparation method of above-mentioned air-entrained concrete building block, and step is as follows:
1. by the flyash of formula ratio, water, desulfurated plaster mixed pulp;
2. evenly add successively cement and the lime of formula ratio, and stir 3-5min;
3. add the aluminium cream of formula ratio to stir;
4. the mixture stirring is poured into mould;
By quietly stopping, cutting, steam press maintenance, go out still technique and make product.
The beneficial effect of air-entrained concrete building block of the present invention is as follows:
1., when growing continuously and fast along with China's economy, environmental pollution and energy dilemma have become the main body of contemporary society's development.The development trend of New Building Materials is complied with this subject requirement just, actively utilizes industry byproduct desulfurated plaster etc., is added in material of construction and uses.This development trend has not only consumed a large amount of industry byproducts, but also has reduced environmental pollution; Meanwhile, solve the difficult buying of the adjusting material plaster of paris used in existing air-entrained concrete building block production process, the problem that purchase cost is high.
2. pair industrial waste utilizes, and realizes recycling economy;
3. desulfurated plaster annual production is huge, has improved the utilization ratio of desulfurated plaster, and price is only 21% of the plaster of paris, and then reduces product cost.
