[0007] detailed description The raw material of the brick body in the present invention is composed of cement, lime, rice straw, sand, fly ash and additives; the configuration ratio is 13.7-13.9% of cement, 49.8-50.0% of lime, 5.4-5.6% of rice straw, and 27.6% of sand ~27.8%, fly ash 2.6~2.8%, additives 0.0027~0.0028%; the raw materials mixed in proportion are fired into city bricks at a temperature of 800~1000℃.

[0008] Before firing, grind the rice straw into sections, or grind it into foam, then mix it with cement, lime, sand, fly ash and additives in proportion, and pour the mixed raw materials into the brick mold. Firing is carried out in a brick kiln at a temperature of 1000°C, and the shape of the formed brick is determined by the brick mold. This method of burning bricks does not use soil, which can effectively reduce soil ecological damage.

Abstract

The invention relates to a rice straw brick making method. A raw material of a brick body is formed by mixing cement, lime, rice straws, sand, pulverized fly ash and an additive and comprises the following compositions in percentage by weight: 13.7-13.9 percent of cement, 49.8-50.0 percent of lime, 5.4-5.6 percent of rice straws, 27.6-27.8 percent of sand, 2.6-2.8 percent of pulverized fly ash and 0.0027-0.0028 percent of additive; and the raw material mixed in proportion is fired into a brick at a temperature of 800-1000 DEG C. The rice straw brick making method has the advantages of low cost, simplicity and the like.

Description

technical field [0001] The invention relates to a method, in particular to a brick firing method. Background technique [0002] As we all know, bricks have been one of the most basic building materials in the construction industry since ancient times. At present, most of the brickware use clay as the main raw material, which is formed after high-temperature firing, such as: blue bricks, red bricks, hollow bricks and so on. However, using soil in large quantities as raw materials will destroy the ecological environment of the land and bring serious ecological losses to the environment. For this reason, it is very necessary for us to provide a method of firing bricks utilizing other materials as raw materials. Contents of the invention [0003] The purpose of the present invention is to provide a method for burning bricks by using rice straw mixed with other materials. [0004] The raw material of the brick body in the present invention is composed of cement, lime, rice s...
