Example Embodiment

[0014] Example 1

[0015] The present invention provides a burn-free brick, the weight ratio of the raw materials is:

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

[0017] The preparation method is:

[0018] (1) All the raw materials are sent into the forming mold of the brick making machine through the material conveyor, and processed into bricks by vibration and pressure. The pressure is 3MPa;

[0019] (2) Carry out steam curing for 12 hours after the brick body is formed. The curing temperature is 85°C to increase the strength of the brick to 70% of the design strength. Then it is put into the finished product storage yard and the finished product is obtained after natural air drying.

Example Embodiment

[0020] Example 2

[0021] The present invention provides a burn-free brick, the weight ratio of the raw materials is:

[0022] 60 parts of water, sludge dried and crushed through 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, 5 parts of shell powder Parts, 5 parts of glass fiber.

[0023] The preparation method is:

[0024] (1) All the raw materials are sent into the forming mold of the brick making machine through the material conveyor, and processed into bricks by vibration and pressure. The pressure is 4MPa;

[0025] (2) After the brick body is formed, natural curing is carried out for 7 days at a curing temperature of 15°C to increase the strength of the brick to 70% of the design strength, and then the brick is placed in the finished product storage yard, and the finished product is obtained after natural air drying.

Example Embodiment

[0026] Example 3

[0027] The present invention provides a burn-free 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, 4 parts of glass fiber.

[0029] The preparation method is:

[0030] (1) All raw materials are sent into the forming mold of the brick making machine through the material conveyor, and processed into bricks by vibration and pressure, and the pressure is 3.5MPa;

[0031] (2) After the brick body is formed, steam curing is carried out for 11 hours at a curing temperature of 90°C to increase the strength of the brick to 70% of the design strength, and then put it into the finished product stacking yard, and the finished product is obtained after natural air drying.

Abstract

The invention relates to a baking-free brick. The baking-free brick comprises the following raw materials in parts by weight: 50-60 parts of water, 100-150 parts of silt, 20-30 parts of electric furnace slag, 5-10 parts of alum, 30-40 parts of silicate cement, 8-12 parts of lime, 2-6 parts of expanded perlite, 3-8 parts of straw, 3-5 parts of shell powder and 3-5 parts of glass fiber, wherein the silt is dried, pulverized and passed through a screen of 20-40 meshes. The baking-free brick is good in quality, has favorable technical performance, is low in cost, can save energy, protect cultivated lands and optimize aquatic environment, and can be widely used for non-load bearing filler walls and load bearing walls of industrial and civil buildings.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an unburned brick and a preparation method thereof. Background technique [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. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the applicant provides a burn-free brick and a preparation method thereof. The non-bur...
