Problems solved by technology

Sintered bricks are solidified on the surface, and their internal solidification is achieved by shrinking when the surface is liquefied and then solidified. Once the surface is damaged, the internal quality is not guaranteed; in addition, the external dimensions and regularity of the product are affected by sintering and it is difficult to standardize

Abstract

A fire-free brick is prepared from cement (9-11 Wt portions), self-burning coal gangue (45-50), grain slag (15-30), stone powder (20-30), water reducing agent (0.2) and sodium sulfate (0.21). Its advantages are high quality, low cost and no environmental pollution.

Description

1. Technical field: [0001] The invention relates to a non-burning brick and a production method thereof, in particular to a non-burning coal gangue non-burning brick and a production method thereof. 2. Background technology: [0002] The current coal gangue sintered bricks are solidified by the sintering temperature, and there are many factors that affect the solidification quality, such as: moisture content, preheating temperature, sintering temperature, especially the section temperature of the kiln, firing time, cooling temperature, etc. If the requirements are met, there will be quality problems. Sintered bricks are solidified on the surface, and their internal solidification is achieved by shrinking when the surface is liquefied and then solidified. Once the surface is damaged, the internal quality is not guaranteed; in addition, the external dimensions and regularity of the product are affected by sintering and it is difficult to standardize. 3. Contents of the inven...
