Technical Field
The invention relates to the field of building materials, in particular to an environment-friendly building material.
Background
Charcoal is a solid combustible mineral formed gradually by ancient plants buried underground and undergoing complex biochemical and physicochemical changes. Coal is known as black gold by people and is industrial food, which is one of main energy sources used in the human world since the eighteenth century, and since the twenty-first century, although the value of coal is not as high as before, coal is still one of indispensable energy sources for human production and life in a long time at present and in the future, the supply of coal is also related to the stability of the development of the industry of China and the aspect of the whole society, and the problem of the supply safety of coal is also the most important part in the energy safety of China.
The coal slag left after the coal is combusted belongs to waste materials and needs to be treated, and the coal slag treatment process has high requirements and certain environmental damage caused by stacking of the coal slag.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide an environment-friendly building material, which is characterized in that coal slag generated after coal is combusted is used in the building material, and the problem of stacking and treating a part of the coal slag is solved.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides an environment-friendly building material which comprises the following components in percentage by weight:
cement; coal ash particles; a thickener; the coal ash particles are solid particles with the particle size of 2mm-5mm which are obtained by crushing coal slag left after coal combustion; and mixing and stirring the cement, the coal ash particles and the thickening agent in proportion to obtain the environment-friendly building material.
Preferably, the cement is portland cement.
Preferably, the thickener is a cellulose ether.
Preferably, the cellulose ether is hydroxypropyl cellulose ether or hydroxypropyl methyl cellulose ether.
Preferably, the coal ash particles are prepared by the following process:
s1, collecting coal cinder, and collecting blocky coal cinder with holes after coal combustion;
s2, primary crushing, namely crushing the collected blocky coal cinder with the holes to obtain coal ash particles with the particle size of 2-5 mm;
s3, primary screening, namely screening coal ash particles with the particle size larger than 5mm by using a screen with the aperture equal to 5mm, crushing the coal ash particles with the particle size larger than 5mm in the step S2, and performing primary screening again to finally obtain all coal ash particles with the particle size smaller than or equal to 5 mm;
and S4, secondary screening, namely screening the coal ash particles with the particle size of less than 2mm by using a screen with the aperture of 2mm, so as to obtain the coal ash particles with the particle size of 2mm-5 mm.
The invention has the beneficial effects that:
the coal slag generated after coal combustion is used in building materials, so that the problem of stacking and processing of part of the coal slag is solved;
the cinder used for the building material is blocky cinder with holes, and when the cinder is used as the building material, the cinder has the effect of keeping warm to a certain extent due to the holes;
the coal cinder belongs to industrial waste, so the coal cinder is cheaper, and the cost of the building material can be reduced when the coal cinder is used for the building material.
