Light cement brick and production method

Abstract

The invention relates to a light cement brick and a production method, and belongs to the production field of a brick for buildings. The existing ordinary brick produced in a traditional method is relatively light in weight and poor in heat insulation effect, and the existing equipment for producing a foam brick has defects such as high cost, complicated procedure and the like. The light cement brick consists of cement, yellow sand, lime and foam particles, wherein the weight percentages of the ingredients are as follows: 24 to 26 percent of cement, 60 to 65 percent of yellow sand, 10 to 16 percent of lime, and the volume ratio of the foam particles in the cement brick is 35 percent. According to the light cement brick, the lime and foam particles are added on the basis of the materials of the ordinary brick, the lime plays a role in absorbing the water, so that a damp-proof function to a house can be realized; and by adding the foam particles to the ordinary brick, not only can the weight of the brick be reduced, but also a heat insulation effect can be realized.

Description

technical field [0001] The invention belongs to the field of making bricks for construction, and in particular relates to a lightweight cement brick and a making method. Background technique [0002] Bricks are often used and indispensable materials in construction. The traditional brick production method is to mix cement, yellow sand and water in a certain proportion through a mixer, and then directly form the bricks used on the construction site through a brick making machine. Then it can be used outdoors for about 20 days, but the quality of this ordinary brick is relatively heavy, and the heat insulation effect is not good. At present, there are also many merchants who have developed a cement foam brick. Its production process is to mix yellow sand, cement, cinder, etc., and then inject it through the cement foaming agent. Foam is formed to reduce the weight of the bricks. Since the foamed raw materials are relatively large, after the foaming is completed, the bricks ne...
