Autoclaved brick prepared from large-mixing-amount steel slag powder and preparation method of autoclaved brick
The invention provides an autoclaved brick prepared from steel slag powder and iron tailings. The autoclaved brick comprises the following components in percentage by weight: 22.4-67.9% of the iron tailings, 20-55% of the steel slag powder, 5-7% of cement, 7-15% of gravels and 0.1-0.6% of a hydroxy carboxylate inhibitor, wherein the water-material ratio is 0.08-0.11. Under the action of the inhibitor, a green brick is pre-maintained, so that the problem of bad stability of the autoclaved brick caused by steel slag is eliminated, and the problem that the autoclaved brick cracks during production by using a large mixing amount of the steel slag as a raw material is solved. The production process of the autoclaved brick is also simplified, the cementitious activities of cement and the steel slag are fully used, the product performance is improved, and the labor intensity and the production cost are reduced.
