Problems solved by technology

For a long time, the sintered bricks widely used in our country still use clay as the main raw material, which not only destroys the cultivated land, but also has high energy consumption in production, poor thermal insulation performance, and bulky bricks, which cannot reflect good advantages in actual engineering operations. sex

Embodiment 1

[0029] A non-burning silt brick, including the following components and the mass percentage content of each component: dredged silt (deducting moisture): 28%; fly ash: 45%; quicklime: 18%; raw gypsum: 8%; Ammonium nitrate: 0.3%; zinc chloride: 0.4%; sodium silicate: 0.15%; chlorine salt series antifreeze: 0.15%.

[0030] The water content of the dredged sludge is 80%. When weighing the dredged sludge, the corresponding water must be deducted. The added amount of antifreeze is suitable for use in winter in cold areas.

[0031] figure 1 It is a flow chart of the method for preparing silt-free burnt bricks according to the present invention.

[0032] Such as figure 1 As shown, a method for preparing silt-free burnt bricks is carried out as follows:

[0033] (1) According to the raw materials of the dredged silt free-burning brick according to claim 1, each component is weighed, stirred until the mixture is uniform, and rolled.

[0034] (2) Feed the raw materials crushed by the wheel to t...

Embodiment 2

[0040] A non-burning silt brick includes the following components and the mass percentages of each component: dredged silt (deducted moisture): 34%; fly ash: 40%; quicklime: 20%; raw gypsum: 5%; Ammonium nitrate: 0.35%; zinc chloride: 0.3%; sodium silicate: 0.1%.

[0041] The water content of the dredged sludge is 80%. When weighing the dredged sludge, the corresponding water must be deducted.

[0042] The preparation method of the dredged silt-free brick in Example 2 is the same as that in Example 1.

Embodiment 3

[0044] A non-burning silt brick, including the following components and the mass percentages of each component: dredged silt (deducted moisture): 40%; fly ash: 35%; quicklime: 16%; raw gypsum: 6.5%; Zinc nitrate: 0.45%; zinc chloride: 0.2%; sodium silicate: 0.1%; chlorine salt series antifreeze: 0.2%.

[0045] The water content of the dredged sludge is 80%. When weighing the dredged sludge, the corresponding water must be deducted. The added amount of antifreeze is suitable for use in winter in cold areas.

[0046] The preparation method of the dredged silt-free brick in Example 3 is the same as the preparation method in Example 1.

Abstract

The invention relates to a sludge baking-free brick. The brick comprises the following components in percentage by mass: 25-40% of dredged sludge (moisture is removed), 30-45% of coal ash, 16-26% of quicklime, 4-8% of raw gypsum, 0.3-0.5% of gelatinizing agent, 0.2-0.4% of accelerant, 0.1-0.15% of sodium silicate and 0-0.25% of anti-freezing agent. Meanwhile, the invention further discloses a preparation method of the sludge baking-free brick. According to the sludge baking-free brick and the preparation method of the sludge baking-free brick, the industrial production can be completely realized, and the produced products can be used for replacing clay sintered bricks, so that not only is the environment protected, but also a mass of earth-rock resources are saved.

Description

technical field [0001] The invention relates to a burn-free brick and a preparation method thereof, more specifically to a burn-free mud brick and a preparation method thereof, and belongs to the technical fields of environmental engineering and geotechnical engineering. Background technique [0002] With the continuous advancement of my country's infrastructure construction, the demand for bricks as building envelope materials in infrastructure projects is also increasing. For a long time, the sintered bricks widely used in our country still use clay as the main raw material, which not only destroys the cultivated land, but also has high energy consumption in production, poor thermal insulation performance, and bulky bricks, which cannot reflect good advantages in actual engineering operations. sex. In recent years, with the in-depth implementation and implementation of the national policy of "banning and restricting clay", research on the preparation of new geotechnical m...
