Embodiment 1

[0019] A method for producing autoclaved aerated concrete blocks by using waste glass, which is made of the following raw materials in parts by weight: 70 parts of desert fine sand, 10 parts of cement, 15 parts of quicklime, 8 parts of waste glass, 0.05 part of aluminum powder paste, 2 parts of straw powder, 3 parts of waste cotton; the specific preparation steps are as follows:

[0020] (1) Use a ball mill to grind desert fine sand and waste glass into a powder with a particle size below 200 mesh, and then use a beater to beat for standby;

[0021] (2) Crush the quicklime with a crusher, and then use a ball mill to grind it into a powder with a particle size below 160 mesh;

[0022] (3) Use a pulverizer to crush the straw into straw powder with a particle size of 30-60 mesh for use;

[0023] (4) Use the popping machine to flick the waste cotton until it is completely fluffy and then use it;

[0024] (5) Mix desert fine sand and waste glass powder after beating, quicklime af...

Embodiment 2

[0029] A method for producing autoclaved aerated concrete blocks by using waste glass, which is made of the following raw materials in parts by weight: 60 parts of desert fine sand, 5 parts of cement, 20 parts of quicklime, 10 parts of waste glass, 0.10 parts of aluminum powder paste, 1 part of straw powder, 2 parts of waste cotton;

[0030] The difference between the preparation method of Example 2 and Example 1 is that in step (5), the water-material ratio of the mixture is 0.7:1; the rest is the same as that of Example 1.

Embodiment 3

[0032] A method for producing autoclaved aerated concrete blocks by using waste glass, which is made of the following raw materials in parts by weight: 80 parts of desert fine sand, 8 parts of cement, 10 parts of quicklime, 5 parts of waste glass, 0.08 parts of aluminum powder paste, 3 parts of straw powder, 5 parts of waste cotton; the specific preparation steps are as follows:

[0033] The difference between the preparation method of Example 3 and Example 1 is that in step (5), the water-material ratio of the mixture is 0.5:1; the rest is the same as that of Example 1.

[0034] After testing, the relevant properties of the concrete block obtained by embodiment 1-3 are as shown in table 1:

Abstract

The invention provides an autoclave aerated concrete block produced from waste glass and a production method thereof. The concrete block is prepared from desert fine sand, cement, quicklime, waste glass and aluminum powder paste. The main preparation steps include: (1) grinding the desert fine sand and waste glass into powder by a ball mill, and conducting beating with a beater for standby use; (2) crushing the quicklime with a crusher, and then performing grinding into powder by the ball mill; (3) putting the beat desert fine sand and waste glass powder, the ball milled quicklime, cement and aluminum powder paste in a stirrer, adding water and stirring the materials fully, thus obtaining a mixture; (4) casting the mixture in a mold, performing initial setting to obtain a large block blank; (5) cutting the large block blank, and then conducting static maintenance; and (6) performing autoclave curing, thus obtaining the product concrete block at the end.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to an autoclaved aerated concrete block produced by using waste glass and a production method thereof. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, glass is not only widely used in housing construction and people's daily life, but also becomes an indispensable material for scientific research and production. In the process of using glass, it is inevitable to produce a lot of glass waste and form a large amount of waste glass. According to conservative estimates, waste glass accounts for 5% of the total domestic waste, and the waste glass produced by the flat glass manufacturing industry alone reaches more than 2 million tons every year, forming a huge waste resource. Glass substances have stable chemical properties, do not rot, burn, or degrade. A large amount of waste glass not only br...
