Problems solved by technology

The disadvantage is: the brick must use cement, which is actually a concrete product, and must be steamed, the process is complicated, and the cost is high
The disadvantage is that it is difficult to have fly ash, steel slag, and calcium carbide slag at the same time in the production site. The cost of collecting and transporting raw materials is high, resulting in high final cost of bricks, which is difficult for users to accept.

Abstract

The environment-protecting high pressure no-baking ardialite brick is made with the material including sand in 100 weight powder, ardialite in 40-60 weight portions, solid phase adhesive in 10-20 weight portions, liquid phase adhesive in 0.1-0.5 weight portions, and sodium humate in 0.5-2 weight portions. The making process includes mixing all the material through stirring, molding the mixture in mold inside brick making machine at pressure not lower than 40 MPa, demolding and curing. The ardialite brick has high and stable strength, long service life and low cost.

Description

technical field [0001] The invention relates to a building brick, in particular to an unfired phosphogypsum brick and a manufacturing method thereof. Background technique [0002] Because clay bricks consume a large amount of non-renewable land resources, they are no longer in line with the national industrial policy. The building materials industry has sought other alternative raw materials such as sandstone, coal gangue, fly ash, phosphogypsum, carbide slag, and foundry steel slag to produce building bricks. However, due to the raw material formula or the production process, either the product quality is not good enough, or the cost is high, which is not economical. [0003] The "environmental protection non-fired sand brick and its preparation method" disclosed by the Chinese patent (publication number CN1272467A) is to mix cement, sand, stone powder and water in a certain proportion, press and form it under a certain pressure through a brick press, and then steam it into...
