Abstract

The invention discloses a light environment-friendly brick prepared from waste brick powder, and a preparation method for the light environment-friendly brick. The light environment-friendly brick prepared by the method comprises the following raw materials in percentage by weight: 50 to 60 percent of polishing brick waste mud, 10 to 15 percent of waste brick powder, 10 to 15 percent of Qidao clay, 10 to 15 percent of aluminum ore, 5 to 10 percent of mung bean mud, 0.3 percent of foaming agent, 0.5 percent of water reducing agent and 0.08 percent of green body intensifier, wherein the polishing brick waste mud is waste mud which is wasted when a polishing brick is produced; and the waste brick powder is brick powder which is wasted when a common brick is produced. The problems about control over foaming rate and flatness of a product in a drying and calcination process can be solved, the prepared finished product is smooth and flat in surface, and closed air holes in the brick are ideal. Meanwhile, the waste brick powder and the waste mud in a ceramic production enterprise are used as raw materials, so industrial waste is treated, production cost is saved, environment is protected, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a lightweight environment-friendly brick produced from waste brick powder and a preparation method thereof. Background technique [0002] At present, the building wall materials in our country have always been dominated by solid clay bricks. Solid clay bricks not only destroy a lot of fertile land, but also consume a lot of energy, and are not conducive to environmental governance and the development of the construction industry. Therefore, building wall materials are becoming more and more important. Gradually change from solid clay bricks to lightweight environmental protection bricks. As a new type of wall material, lightweight environmentally friendly bricks have the advantages of light weight, high strength, no pollution, low cost, sound insulation and heat preservation because of the many closed pores inside. The formation of pores inside the lightweight environmentally friendly bricks is determined by the foaming proces...
