Preparation method of aerated brick with good waterproof performance
The invention discloses a preparation method of an aerated brick with good waterproof performance. The preparation method comprises the following steps: 30-32 parts of siliceous filler, 4-6 parts of a calcium oxide expanding agent, 2-4 parts of blast-furnace ash and 6-8 parts of modified paper fiber are mechanically ground into powder and uniformly stirred according to the formula proportion, then water in the volume ratio being 12%-15% is added, and raw meal balls with the particle sizes ranging from 4 mm to 6 mm are prepared from the mixture by a ball mill and are dried for 2-3 h at the temperature ranging from 100 DEG C to 120 DEG C; 5-10 parts by mass of gypsum powder, 2-4 parts by mass of activated carbon and 20-30 parts by mass of cement are mixed with the raw meal balls and are subjected to fine grinding. The siliceous filler, the blast-furnace ash, the activated carbon and reasonable component proportion are adopted, so that energy saving and environmental protection are realized, the structure is form, the waterproof performance is good, various types of mining waste are used abundantly, a new raw material source is provided for hollow bricks, and the weight of a brick body is reduced.
