Problems solved by technology

[0002] Quartz tailings is one of the tailings resources, which is the waste residue discharged from the extraction of calcium fluoride from the fluorite mine by the chemical plant, and a large amount of waste residue is piled up as waste, which not only causes environmental pollution, but also makes a large amount of the waste residue beneficial. The ingredients are not comprehensively utilized, resulting in waste of raw materials and intermediate products in chemical plants, and the resources on the earth cannot be rationally developed and utilized

Embodiment 1

[0024] Quartz tailing insulation brick, the raw materials are 8% cement, 45% crushed stone, 8% light aggregate and 39% quartz tailing powder in mass percentage. The lightweight aggregate uses expanded vitrified microbeads with a vitrification rate of 60%, and the expanded vitrified microbeads are doped with polyurethane accounting for 3% of the mass of the expanded vitrified microbeads. Quartz tailings powder is ground fluorite tailings waste and passed through a 100-mesh sieve; crushed stone is crushed to a particle size of 2mm. Portland cement used in cement.

[0025] The preparation method comprises the following steps:

[0026] (1) Prepare crushed stone and quartz tailings powder to obtain a raw material mixture; mix lightweight aggregate and cement with water with a mass ratio of 10-15%, and then fully stir with the raw material mixture to obtain clinker;

[0027] (2) Send the clinker into the buffer hopper through the conveyor, carry out two-way hydraulic forming throu...

Abstract

The invention relates to the technical field of building materials, in particular to a quartz tailing insulation brick and a preparation method thereof. By using cement, crushed stone, lightweight aggregate, and quartz tailing powder, the quartz tailing powder is used to replace the traditional insulation brick preparation process The fly ash used makes the effective components in the raw materials interact with each other during the preparation of the insulation bricks, and on the premise that the silicon content in the quartz tailing bricks is high, it promotes the silicate water of the bricks in the autoclave. Chemical reaction to enhance the strength of insulation bricks. Compared with fly ash, it has better compatibility with cement mortar through the use of quartz tailings powder, which can ensure the firm and lasting combination between each other and improve the bonding of bricks. performance, avoid cracking and falling off, and make full use of quartz tailings, realize waste recycling and reduce costs.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a quartz tailing insulation brick and a preparation method thereof. Background technique [0002] Quartz tailings is one of the tailings resources, which is the waste residue discharged from the extraction of calcium fluoride from the fluorite mine by the chemical plant, and a large amount of waste residue is piled up as waste, which not only causes environmental pollution, but also makes a large amount of the waste residue beneficial. The components cannot be comprehensively utilized, resulting in the waste of raw materials and intermediate products in chemical plants, and the resources on the earth cannot be rationally developed and utilized. [0003] For this reason, some researchers conducted a comprehensive analysis and research on the waste residues discharged from chemical plants, and used them in the construction industry, so that the waste residues in chemical...
