Baking-free brick and production method thereof

Abstract

The invention provides a baking-free brick and a production method thereof. The soil and regenerated aggregate can be added into the manufacturing raw material as raw materials for brick making, cement is used as a gelling agent, the actions of admixtures and a fusion agent are used to package and blend the soil and the fusion agent, the waste residue and waste material is fully utilized, and thusthe prepared baking-free brick has the characteristics that the strength is high, the waterproof effect is good, the curing period is short, the application of raw materials is wide, the resource comprehensive utilization benefit is high, the cost is low, the production process is environment-friendly, the raw materials can be recycled and reused, and the like.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an unburned brick and a production method thereof. Background technique [0002] Common traditional building bricks include red bricks, cement bricks and lime-sand bricks. Red brick is a sintered building made of clay, shale, coal gangue, etc., which are crushed, mixed and kneaded, pressed manually or mechanically, and fired with an oxidizing flame at a temperature of about 900 degrees Celsius after drying. Bricks, because they use a lot of clay, which mainly comes from the mellow soil of the cultivated land, not only destroy the green area, cause water and soil erosion, but also reduce the area of ​​cultivated land, and the red brick wastes a lot of fuel during the sintering process, and the exhaust gas from burning has a great impact on the environment. The environment has a great impact, so red bricks are already a building material banned by the state. Cement bricks refer ...

AI Technical Summary

Problems solved by technology

However, the bricks made by the prior art still have some disadvantages relative to the traditional building bricks: for example, the bricks of construction waste have low strength and can only be used for low-rise buildings or non-load-bearing parts in high-rise buildings; secondly, the raw materials The soil content in the brick must be less than 3%, because the inertia of the soil is very strong, and the cement and soil in the raw material cannot undergo any chemical reaction. When the soil content in the brick is too high, it will greatly affect the quality of the brick; and in During long-term use, the soil is easily weathered, the bricks disintegrate, and eventually the bricks fail

There is no record of using soil as raw material to make unburned bricks in the prior art
