Baking-free brick with waste as main material

Abstract

The invention discloses a baking-free brick with wastes as main materials. The baking-free brick is manufactured from following materials: 40-50% of a power plant waste fly ash, 10-20% of furnace slag, 10-20% of cement, 10-20% of river sand, 1-3% of a binding agent and a proper amount of water. The raw materials are uniformly mixed and are manufactured into green bricks through a full-automatic hydraulic moulding machine and then the green bricks are naturally dried. By means of production of the baking-free brick from the industrial residues, an object of saving land, utilizing waste, protecting environment and saving energy is achieved.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to an unfired brick prepared by using waste as the main material. Background technique [0002] Unburned bricks are made by mixing cement and coal ash into a mixer to mix evenly, injecting or putting them into a mold, vibrating and pressurizing in the mold, forming a brick, and then drying it naturally. [0003] According to relevant national data, in terms of raw materials, the stockpile and annual discharge of solid waste in my country are very huge. This kind of waste is stored in artificial storage by natural accumulation method. These wastes not only occupy a large amount of land, but also pollute the surrounding areas. The environment, and the need to invest a large amount of waste disposal funds that cannot be recovered every year, have become a heavy burden for enterprises. At present, there are thousands of large and medium-sized coal production enterprises and ther...
