Problems solved by technology

[0003] my country is a country with abundant resources, a large population, and a large construction country. With the rapid increase in the number of marriageable population, the rapid development of my country's real estate industry has been driven, and the area of ​​newly built housing has increased year by year. While the construction industry is developing rapidly, a large amount of construction waste is also produced. Due to the unreasonable design of the house structure and the different preferences of the owners for the decoration of the new house, a large amount of construction waste such as bricks, tiles and concrete will be generated during the construction and decoration of the house. Such waste resources have low value and are difficult to degrade. , Difficult to deal with, in the actual management process, they are generally directly landfilled or stacked in the open air, which has caused serious difficulties to urban management, and stacked in the open air occupies a large amount of land resources

Abstract

The invention relates to a wollastonite fiber doped coal gangue brick. According to the invention, a carbide slag slurry with a calcium hydroxide solid content mass percentage of 20-30% is adopted as a liquid component for replacing a large amount of water resource needed by a traditional coal gangue brick or autoclaved brick production process. Also, a technical difficulty of carbide slag slurry treatment is solved. When carbide slag slurry, which is a strongly alkaline liquid material, is mixed and stirred with the other components such as tailings, coal gangue and desulfurization gypsum, the components can be subjected to a modification treatment, such that a product can be provided with better physical strength, and a finished product is provided with a property of fast water absorption. Wollastonite fiber is adopted as a structural reinforcement agent, such that the tensile properties and fracture toughness of the finished product can be effectively enhanced.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a wollastonite fiber-doped gangue brick and a production method thereof. Background technique [0002] A new type of wall filling material prepared by using fly ash, coal gangue, cinder, tailings slag, calcium carbide slag, construction waste, etc. as the main raw materials without high-temperature calcination, directly casting and curing is called unburned brick, also known in the industry as Autoclaved bricks or foam bricks. [0003] my country is a country with abundant resources, a large population, and a large construction country. With the rapid increase in the number of marriageable population, the rapid development of my country's real estate industry has been driven, and the area of ​​newly built housing has increased year by year. While the construction industry is developing rapidly, a large amount of construction waste is also produced. Due to the unreasonable de...
