The Chinese invention patent with the application number 201611249340.3 discloses a method for preparing green bricks, which uses shale, clay, sludge, waste ceramics, vermiculite, volcanic ash, tofu swill, pine and cypress bark, bamboo chips and carbon as raw materials. The cost is reduced, but the high-temperature sintering method of bricks is used for firing, and the cycle is long, and the burning of fuel is not conducive to environmental protection
The Chinese invention patent with the application number 201510777991.9 discloses a production process of environmentally friendly imitation blue bricks. Stone powder and cement are used as raw materials to prepare antique blue bricks with high strength and full use of solid waste. However, colored pigments are required to pollute the environment
And the color of the blue bricks produced is quite different from that of traditional clay bricks

Abstract

The invention provides a grey brick taking diabase as a raw material and belongs to the field of building materials. The grey brick is prepared from the following raw materials in percentage by weight: 75-90% of diabase, 2-10% of fly ash, 0-0.15% of carbon black, 0.3-1% of baregin and 6-15% of cement. The grey brick taking the diabase as the raw material takes the diabase as the main raw material,has a color close to that of the traditional clay grey brick and is prepared by a compression molding method, the cost is reduced, and environment stress is relieved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a green brick using diabase as a raw material and a preparation method thereof. Background technique [0002] Traditional blue bricks are fired bricks. The main raw material is clay. After the clay is mixed with water, it is extruded and shaped, and then baked in a brick kiln until it is cooled with water (about 1000 degrees), so that the iron in the clay is not completely oxidized, so that it has a better quality. Weather resistance, water resistance and other characteristics. For the excessive use of clay, my country has banned the production of clay bricks in 2010, and the traditional high-temperature firing process has high production costs and long cycles, requiring the burning of a large amount of coal, causing certain pollution to the environment. [0003] In order to save costs and relieve environmental pressure, people add coal gangue, furnace ash or cinder and other r...
