High ceramic powder content baking-free brick

Abstract

The invention belongs to the technical field of building materials and in particular relates to a high ceramic powder content baking-free brick. The high ceramic powder content baking-free brick is characterized by being prepared from the following raw materials in parts by weight: 10 to 25 parts of ceramic powder, 30 to 50 parts of coal ash, 15 to 25 parts of yellow ground, 10 to 20 parts of cement, 0.1 to 0.3 part of rocky sand crystal, 0.1 to 0.3 part of early strength agent and 10 to 25 parts of water. The high ceramic powder content baking-free brick provided by the invention has the beneficial effects that the baking-free brick is prepared by taking the ceramic powder and coal ash as main raw materials, excellent chemical properties including wear resistance, decay resistance and stability of the ceramic powder are utilized, so that the inner structure of the baking-free brick is optimized, and the mechanical strength and stability of the baking-free brick are promoted. The baking-free brick is abundant in raw material, environment-friendly and free of pollution. The production process is simple, the investment is less, the cost is low, the benefit is good and the market competitiveness is strong.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an unfired brick with high content of ceramic powder. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. As the main solid waste discharged from coal-fired power plants, fly ash is also one of the largest industrial wastes in my country. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing at a rate of 200 million tons per year. Increase. [0003] In order to turn waste into treasure and turn harm into profit, fly ash has been studied and utilized in many fields. Fly ash has been widely used in construction, building materials, water conservancy, etc., especially with fly ash as the main material. The manufacture and production of non-burning bricks, but currently the non-b...

[0003] In order to turn waste into treasure and turn harm into profit, fly ash has been studied and utilized in many fields. Fly ash has been widely used in construction, building materials, water conservancy, etc., especially with fly ash as the main material. The manufacture and production of unburned bricks, but currently unburned bricks made of fly ash as the main raw material have disadvantages such as poor freeze-thaw resistance, easy cracking, and brick weight.
