Abstract

The invention discloses an environment-friendly brick with a good forming effect. The environment-friendly brick is prepared from the following raw materials in parts by weight: 50-70 parts of fine iron tailings, 20-40 parts of coarse iron tailings, 15-25 parts of building solid waste crushed powder, 6-10 parts of No.325 cement, 1-3 parts of a liquid additive and 1-3 parts of water. The inventionfurther provides a preparation method of the environment-friendly brick with the good forming effect. During preparation, the coarse iron tailings are hard in texture and high in strength and can replace aggregate. The preparation method comprises the following steps: proportionally adding the raw materials, stirring, adding the liquid admixture, stirring, and pressing. The formed product is compact in structure, free of surface cracks and free of dispersion phenomenon when being taken out of the mold, and the appearance meets the production standard. The compression resistance is 34.2 MP.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly materials, and in particular relates to an environment-friendly brick with good molding effect and a preparation method thereof. Background technique [0002] Manufactured by using fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, industrial waste, waste incineration slag, etc. (one or more of the above raw materials) as the main raw materials without high-temperature calcination A new type of wall material is called environmental protection brick. [0003] The molding effect and heat resistance of the environmental protection bricks in the prior art cannot meet the needs of actual use, so it is urgent to develop an environmental protection brick with a good molding effect to solve the problems in the prior art. Contents of the invention [0004] The object of the present invention is to provide an environmentally friendly brick with good moldi...
