Abstract

The invention relates to the technical field of environment-friendly brick manufacturing processes. The invention further discloses an environment-friendly brick manufacturing process for replacing natural quartz sand with fine aggregate processed from industrial metallurgical tailings. The raw materials comprise a fine aggregate, a subbase layer comprises cement, a cement mixture and rigid polyurethane fiber glue, the fineness modulus of the fine aggregate industrial sand is within the range of 2.4-2.8, and the fineness modulus of natural sand is preferably within the range of 2.2-3.3. According to the environment-friendly brick manufacturing process for replacing natural quartz sand with fine aggregate processed from industrial metallurgical tailings, the fine aggregate is used for replacing natural quartz sand, and the product has the advantages of high water stability, favorable freezing resistance, favorable heat insulation property and wide application range, can be used as a decorative brick, a road brick and the like, and can also be used as a color brick by adding a dye.

Description

technical field [0001] The invention relates to the technical field of manufacturing technology of environmental protection bricks, in particular to a manufacturing technology of environmental protection bricks in which fine aggregate processed from industrial metallurgical tailings replaces natural quartz sand. Background technique [0002] Using fly ash, coal cinder, coal gangue, tailings slag, chemical slag or natural sand, sea mud, industrial waste and waste incineration slag as the main raw materials, a new type of wall material manufactured without high temperature calcination is called environmental protection. brick. [0003] With the development of science and technology and the improvement of people's living standards, people have higher and higher requirements for the environmental protection of the manufacturing industry. The previous brick manufacturing process, such as a composite permeable brick manufacturing process proposed by Chinese patent CN109020490A, th...
