MU15 autoclaved fly ash brick is a building material, the main raw material is fly ash, by adding an appropriate amount of lime, gypsum and other admixtures, through mixing, molding, autoclaving curing and other processes. This kind of brick has the characteristics of light weight, high strength, good durability and excellent fire performance, and is a green and environmentally friendly building material.
Fly ash is a type of industrial waste residue, which is the waste residue discharged from the coal-fired pulverized boiler of thermal power plants, which is mainly composed of tiny spherical particles. This waste residue has great activity and can be used as an admixture in building materials. The strength grade of autoclaved fly ash bricks made of fly ash can reach MU15, that is, the compressive strength can reach more than 15MPa.
The production process of autoclaved fly ash bricks mainly includes the preparation, mixing, molding, autoclaving and curing of raw materials. Firstly, fly ash, lime, gypsum and other raw materials are mixed and stirred according to a certain proportion, and then the mixture is made into a certain shape of bricks through a molding machine, and then the bricks are put into an autoclave for autoclave curing, and finally the autoclaved fly ash bricks with certain strength and performance are obtained.
Compared with traditional clay bricks, autoclaved fly ash bricks have many advantages. First of all, the autoclaved fly ash bricks have high strength and good durability, which can meet the load-bearing and durability requirements of the buildingSecondly, the light weight of autoclaved fly ash bricks can reduce the dead weight of the building and improve the seismic performance of the buildingThirdly, no clay is used in the production process of autoclaved fly ash bricks, which can reduce the consumption and destruction of land resources;Finally, autoclaved fly ash bricks have excellent environmental performance, which can effectively use industrial waste residue and reduce environmental pollution.
In practical applications, autoclaved fly ash bricks can be used in various types of construction and civil engineering, such as residences, office buildings, workshops, roads, bridges, etc. Due to its excellent fire performance and thermal insulation performance, autoclaved fly ash bricks are also widely used in occasions with high fire protection requirements. In addition, since no water is used in the production of autoclaved fly ash bricks, it is also suitable for areas where water is scarce.
While autoclaved fly ash bricks have many advantages, there are also some drawbacks. For example, the production of autoclaved fly ash bricks requires a large amount of electrical energy, which increases the production costAt the same time, the production of autoclaved fly ash bricks requires large-scale autoclaves and other equipment, and the requirements for equipment are highIn addition, the production of autoclaved fly ash bricks requires a certain level of technology and management, and the quality of production personnel is required.
In order to improve the performance and quality of autoclaved fly ash bricks, some new technologies and processes are applied to the production process. For example, the use of ultra-fine grinding technology can improve the activity of fly ash, thereby improving the strength and durability of autoclaved fly ash bricks;The use of active activator can further activate the activity of fly ash and improve the performance of autoclaved fly ash bricksThe surface of autoclaved fly ash bricks can be modified and enhanced by surface treatment technology, and its decoration and use performance can be improved.
In addition to the traditional autoclaved curing methods, some new curing methods are also applied to the production of autoclaved fly ash bricks. For example, room temperature curing can reduce energy consumption and production costs;Natural conservation methods can use rainwater under natural conditions for maintenance and reduce water consumption;The fast curing method can shorten the curing time and improve the production efficiency.
To sum up, MU15 autoclaved fly ash brick, as a new type of building material, has broad application prospects and market potential. Through continuous R&D and technological innovation, the performance and quality of autoclaved fly ash bricks can be improved, and their application range can be further broadened. At the same time, strengthening production management and environmental protection measures can promote the sustainable development of the autoclaved fly ash brick industry and make greater contributions to the development of the construction industry and environmental protection.
