Problems solved by technology

[0002] my country's traditional brick-making technology is to use clay to fire bricks. This technology has the following disadvantages: 1. Destruction of cultivated land. my country's production of solid clay bricks consumes more than one billion cubic meters of clay resources every year, which is equivalent to destroying 500,000 mu of land; 2. Consumption of a large amount of coal resources. According to incomplete statistics, my country consumes more than 70 million tons of standard coal each year due to the production of clay bricks; 3. Pollution to the environment. A lot of carbon dioxide is released into the air

Embodiment 1

[0015] The invention provides a non-burning brick, the weight ratio of the raw materials is:

[0016] 50 parts of water, sludge dried and crushed through a 20-mesh sieve: 100 parts, 20 parts of electric furnace slag, 5 parts of alum, 30 parts of Portland cement, 8 parts of lime, 2 parts of expanded perlite, 3 parts of straw, 3 parts of shell powder parts, glass fiber 3 to 5 parts.

[0017] Its preparation method is:

[0018] (1) Send all the raw materials into the forming mold of the brick making machine through the material conveyor, and process them into brick bodies through vibration and pressure, and the pressurization pressure is 3MPa;

[0019] (2) After the brick body is formed, steam curing is carried out for 12 hours. The curing temperature is 85°C, so that the strength of the brick rises to 70% of the design strength.

Embodiment 2

[0021] The invention provides a non-burning brick, the weight ratio of the raw materials is:

[0022] 60 parts of water, sludge dried and crushed through a 40-mesh sieve: 150 parts, 30 parts of electric furnace slag, 10 parts of alum, 40 parts of Portland cement, 12 parts of lime, 6 parts of expanded perlite, 8 parts of straw, and 5 parts of shell powder parts, glass fiber 5 parts.

[0023] Its preparation method is:

[0024] (1) Send all the raw materials into the forming mold of the brick making machine through the material conveyor, and process them into brick bodies through vibration and pressure, and the pressurization pressure is 4MPa;

[0025] (2) Carry out natural curing for 7 days after the brick body is formed, and the curing temperature is 15°C, so that the strength of the brick is increased to 70% of the design strength, and then put into the finished product storage yard, and the finished product can be obtained after natural air drying.

Embodiment 3

[0027] The invention provides a non-burning brick, the weight ratio of the raw materials is:

[0028] 55 parts of water, dried sludge and crushed through a 20-mesh sieve: 120 parts, 25 parts of electric furnace slag, 8 parts of alum, 35 parts of Portland cement, 10 parts of lime, 4 parts of expanded perlite, 6 parts of straw, 4 parts of shell powder parts, glass fiber 4 parts.

[0029] Its preparation method is:

[0030] (1) Send all the raw materials into the forming mold of the brick making machine through the material conveyor, and process them into brick bodies through vibration and pressure, and the pressurization pressure is 3.5MPa;

[0031] (2) After the brick body is formed, steam curing is carried out for 11 hours. The curing temperature is 90°C, so that the strength of the brick rises to 70% of the design strength.
