Abstract

The invention discloses a high-strength fly ash brick and a preparation method thereof, and belongs to the technical field of building material preparation, the preparation method of the fly ash brick comprises the following steps: 1, mixing and stirring fly ash, gypsum, calcium carbonate, calcium chloride and potassium sulfate to obtain a mixture; mixing and stirring the mixture with a reinforcing agent, cement and zeolite in parts by weight, and adding water in the stirring process to obtain a mixed material; and 2, carrying out digestion treatment on the mixed material; carrying out compression molding treatment to obtain a green body, transferring the obtained green body into a still kettle, and curing for 12 hours to obtain the high-strength fly ash brick. The reinforcing agent in raw materials of the fly ash brick takes brucite fiber as a matrix, the surface of the brucite fiber is coated with a layer of polyphosphoric acid, the polyphosphoric acid and a flame-retardant component are combined in an ionic bond or coordination form, the flame-retardant component is introduced into the surface of the brucite fiber to form a polyphosphamide coating layer, the mechanical property is improved by adding the reinforcing agent, and the flame retardant property is improved.

Description

technical field

[0001] The invention belongs to the technical field of building material preparation, and in particular relates to a high-strength fly ash brick and a preparation method thereof. Background technique

[0002] As a solid discharge from power plants, fly ash is difficult to deal with and expensive to deal with. At the same time, the stacking of fly ash is harmful to the environment, mainly because it occupies land and flies with the wind, polluting the atmosphere and the surrounding environment. Therefore, it is very important to carry out the utilization of fly ash. In the comprehensive utilization of fly ash, it is mainly used for fly ash building materials. However, due to the poor gelatinization and freeze-thaw resistance of fly ash, it is not durable, and it is easy to cause dust and sand, so the amount of fly ash is relatively low. . The autoclaved fly ash bricks currently used in the market are mainly for the activation and utilization of fly ash. Dop...
