Abstract
The invention discloses a method for producing an aerated building block by using doping carbide slag. The method comprises the following steps: 1) mixing raw materials consisting of, on a dry basis, 55 to 65 parts by mass of modified fly ash, 6 to 10 parts by mass of dihydrate gypsum, 20 to 35 parts by mass of cement and 10 to 12 parts of carbide slag; 2) before fine grinding, weighing 60 to 70 parts by mass of inorganic garbage and 2 to 3.5 parts by mass of aluminum powder, uniformly mixing crushed fly ash, cement, dihydrate gypsum and carbide slag with inorganic garbage and aluminum powder and then carrying out fine grinding; and 3) putting a crushed ceramic waste material and a dry material obtained after fine grinding into a stirring apparatus, adding water and carrying out full mixing. According to the invention, the usage amount of the inorganic garbage is great, energy conservation and environmental protection are realized, the problem of environmental pollution caused by stockpiling treatment of inorganic garbage is alleviated, and a novel raw material is provided for a hollow brick.
Description
Technical field
The present invention relates to building material field, specifically belong to a kind of doping carbide slag production aerating hollow brick method.
Background technology
For a long time, the comprehensive utilization of carbide slag is a global problem always, although the comprehensive utilization of carbide slag has been carried out to a large amount of research both at home and abroad, due to various reasons technical and economically, great majority are not put to industrial realization.
Described in comprehensive, with carbide slag, be that auxiliary material is produced cement, wall body brick, pavement material and had been reported, the production that the inorganic refuse of usining is used for aerated-block as main raw material yet there are no report.
Summary of the invention
The object of the present invention is to provide a kind of doping carbide slag production aerating hollow brick method, inorganic refuse consumption is large, energy-conserving and environment-protective, alleviates useless inorganic refuse and stores up the problem of environmental pollution that processing brings, simultaneously for hollow brick provides new raw material sources.
Technical scheme of the present invention is as follows:
A doping carbide slag production aerating hollow brick method, the method includes following steps:
(1), by following butt mass parts mixing raw material:
(2) mass parts, before fine grinding is got the inorganic refuse of 60-70 part and the aluminium powder of 2-3.5 part, and flyash, cement, dihydrate gypsum and carbide slag after the modification after fragmentation are mixed to rear fine grinding with inorganic refuse and aluminium powder;
(3), the siccative after ceramic waste material after fragmentation and fine grinding is put in whipping device, and add water and fully stir;
(4), the 0.04-0.06% that stirs material quality by above-mentioned steps (3) adds aluminium scrap powder, stirs the 0.003-0.005% of material with suds-stabilizing agent;
(5) slurry, after above-mentioned steps (4) is stirred is at 60-75 ℃ of temperature, and the quiet foamed time that stops is 2-3h, and the quiet outside temperature of stopping is 20-30 ℃;
(6), foamed slurry is injected into and in forming mould, forms green compact, is evacuated down to 0--0.08Mpa in forming mould, keeps 0.8 hour, boost to again-0.08-1.0Mpa, keep 1.7 hours, be finally depressured to 1.2-0.2Mpa, green compact obtain aerating hollow brick finished product through vapor cure.
In described (4) step, by above-mentioned steps (3), stir 0.05% of material quality and add aluminium scrap powder, stir material 0.004% with suds-stabilizing agent.
The present invention compared with prior art tool has the following advantages:
Compare with other material of construction, the present invention's inorganic refuse used is without can directly being used through dehydration, drying treatment, and inorganic refuse consumption is large, all over 50%.
Compare with other building blocks, the aerated-block unit weight that the present invention produces is light, and intensity is high, and the bearing wall or the interior wall partition that are specially adapted to Highrise buildings are used.
Compare with aerated-block, main raw material of the present invention is inorganic refuse, is conducive to solve inorganic refuse and stores up the problem of environmental pollution of processing and bringing.
In a word, the practical situation that the present invention is large in conjunction with China's inorganic refuse amount, utilization ratio is low, take full advantage of composition structure and the chemical property of various materials, formed and take the mineral structure that ca aluminosilicate, hydrated calcium silicate etc. are main body, its product performance meet load-bearing for building and non-lbearing wall material specification of quality.Building block main raw material(s) is useless building waste, and usage quantity is large, is conducive to solve inorganic refuse and stores up the problem of environmental pollution of processing and bringing, for the recycling of inorganic refuse has been opened up a new approach that utilizes.
