Abstract
The invention discloses a method capable of utilizing mine tailings to produce an aerated hollow brick. The method comprises the following steps: (1), mixing such materials in dry basis mass part as main tailings, lime, coal ash or yellow phosphorus slag, and the like; (2), according to the step (1), adding water in 85-95 percent of the mixed material dry basis, adding waste aluminum power in 0.04-0.06 percent of the mixed material dry basis, adding gypsum in 9-11 percent of lime, and adding triethanolamine in 0.1-0.3 percent of waste aluminum power. According to the invention, a larger amount of mine tailings can be used to achieve the purposes of energy conservation and environment protection and relieve the environment pollution caused by processing the mine tailings pile, and a novel material source is provided for the hollow bricks.
Description
Technical field
The present invention relates to the building material field, specifically belong to a kind of method of utilizing the mine tailings to prepare the aerating hollow brick.
Background technology
The mine tailings is one of product of separation operation in the ore dressing, and in the product of this operation, the content of its useful component is minimum.Under current condition of technology and economy, the ore deposit of further sorting claims true tailings again.For a long time, the comprehensive utilization of mine tailings is a global problem always, although a large amount of research has been carried out in the comprehensive utilization of mine tailings both at home and abroad, because technical and various reasons economically, great majority are not put to industrial realization.
Comprehensively described, be that auxiliary material is produced cement, wall body brick, the existing report of pavement material with the mine tailings, yet there are no report with building waste as the production that main raw material is used for aerated-block.
Summary of the invention
The object of the present invention is to provide a kind of method of utilizing the mine tailings to prepare the aerating hollow brick, mine tailings consumption is big, and energy-conserving and environment-protective are alleviated the mine tailings and are stored up problem of environmental pollution and the safety problem that processing brings, and provide new raw material sources for hollow brick simultaneously.
Technical scheme of the present invention is as follows:
A kind of method of utilizing the mine tailings to prepare the aerating hollow brick is characterized in that carrying out according to following steps:
(1), by following butt mass parts mixing raw material:
Mine tailings 60-80 part
Paris white 10-20 part
Lime 8-10 part
Flyash 20-30 part
Cement 10-15 part
Redispersible latex powder 2-5 part
(2), the 85-95% by above-mentioned steps (1) mixing raw material butt quality adds water, the 0.04-0.06% of mixing raw material butt quality adds that aluminium scrap powder, 0.5-2% add lignocellulose, 1-2% adds sebacic acid propylene glycol polyester, the 15-20% of lime quality adds gypsum, and the 0.1-0.3% of aluminium scrap opaque amount adds trolamine;
(3), the slurry after above-mentioned steps (2) stirred under 50-80 ℃ of temperature, foamed time 20-40min;
(4), with the foaming slurry of above-mentioned steps (3) under normal pressure vapor cure 4-8 hour green compact, and cut into corresponding size;
(5), with the green compact of above-mentioned steps (4) at 0.7-0.9Mpa vapor cure 18-22h, namely get aerating hollow brick finished product.
Add soda ash in step (2), add-on is to put 3-4kg soda ash in every cubic metre of mixed slurry.
The present invention compared with prior art has following advantage:
Compare with other building blocks, the aerated-block unit weight that the present invention produces is light, the intensity height, and the bearing wall or the interior wall that are specially adapted to Highrise buildings cut off usefulness.
Mine of the present invention tailings consumption is big, and energy-conserving and environment-protective, alleviates the mine tailings and stores up problem of environmental pollution and the safety problem that processing brings, and provides new raw material sources for hollow brick simultaneously.

25 parts in flyash
15 parts of cement
4 parts of redispersible latex powders
(2), add water by 85% of above-mentioned steps (1) mixing raw material butt quality, 0.04% of mixing raw material butt quality adds aluminium scrap powder, 1% and adds lignocellulose, 1% and add sebacic acid propylene glycol polyester, 15% of lime quality adds gypsum, and 0.1% of aluminium scrap opaque amount adds trolamine;
(3), the slurry after above-mentioned steps (2) stirred under 70-80 ℃ of temperature, foamed time 30-40min;
(4), with the foaming slurry of above-mentioned steps (3) under normal pressure vapor cure 4-8 hour green compact, and cut into corresponding size;
(5), with the green compact of above-mentioned steps (4) at 0.8-0.9Mpa vapor cure 18-22h, namely get aerating hollow brick finished product.Add soda ash in step (2), add-on is to put 3-4kg soda ash in every cubic metre of mixed slurry.
The cubes that the hollow brick that the present invention is produced cuts into 100mm * 100mm * 100mm carries out Performance Detection, and detected result is as follows: ultimate compression strength 3.18Mpa, unit weight 0.65g/m3, shrinkage value 0.67mm/m, weight loss 4.1%, frost resistance loss of strength 18.41%.
Claims (2)
1. method of utilizing the mine tailings to prepare the aerating hollow brick is characterized in that carrying out according to following steps:
(1), by following butt mass parts mixing raw material:
(2), the 85-95% by above-mentioned steps (1) mixing raw material butt quality adds water, the 0.04-0.06% of mixing raw material butt quality adds that aluminium scrap powder, 0.5-2% add lignocellulose, 1-2% adds sebacic acid propylene glycol polyester, the 15-20% of lime quality adds gypsum, and the 0.1-0.3% of aluminium scrap opaque amount adds trolamine;
