Problems solved by technology

However, considering the difference in real life and different regions, it is not an easy task to find a variety of waste residues to be used together. Moreover, waste residues have a lot of impurity ions due to different raw materials and minerals, so it is not possible to solve them with one formula.

Embodiment example 1

[0020] Fluorogypsum-based floor tiles consist of the following raw materials in parts by weight:

[0021] Fluorogypsum powder: 72kg, fly ash: 12kg, cement: 6.5kg, aggregate: 8kg, activator: 1.23kg, fiber: 0.12kg, water reducing agent: 1kg, water retaining agent 0.05kg, water 12.2kg;

[0022] The fluorogypsum powder is the waste residue produced for the production of hydrofluoric acid, mixed with quicklime at 5.2%-7.5% of the mass of the fluorogypsum, mixed and finely ground, passed through a 250-mesh sieve and having a pH>12.

[0023] The selected fly ash meets the requirements of Class I fly ash in the national standard GB / T1596 "Fly Ash Used in Cement and Concrete".

[0024] The cement selected is 42.5R ordinary Portland cement.

[0025] The selected aggregate is river sand with a particle size of 20-40 mesh.

[0026] The selected activator is a combination of alunite, sodium sulfate, triethanolamine and sodium carbonate in a ratio of 4:2:2:1.

[0027] The preparation met...

Abstract

The invention provides a preparation method of a fluorgypsum floor tile. The fluorgypsum floor tile is prepared from raw materials in parts by weight as follows: 71-78 parts of fluorgypsum powder, 5-14 parts of fly ash, 5-10 parts of cement, 5-15 parts of aggregates, 0.5-1.5 parts of an exciting agent, 0.05-0.35 parts of fibers, 0.05-0.5 parts of a water reducing agent and 0.02-0.5 parts of a water-retaining agent, and a ratio of water to materials is 0.1-0.135. According to the preparation method, slag mixing amount is large, cost is low, no secondary pollution is produced, and the preparation technology is simple; the raw materials are easily available, no secondary impurities are added to the raw materials, and the prepared fluorgypsum floor tile is stable in quality, high in strength,good in wear resistance and impact resistance and wide in application range.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of fluorogypsum floor tiles. Background technique [0002] Fluorogypsum is a by-product of the production of hydrofluoric acid, which belongs to Type II anhydrite. Every ton of hydrofluoric acid produced produces about 3.6 tons of fluorogypsum, and the annual emission exceeds 6 million tons. Most of the fluorogypsum is stockpiled as general solid waste after a little neutralization treatment. Direct stockpiling not only occupies land, but also pollutes the soil and groundwater environment. Today, with the increasing consumption of natural resources, the use of industrial solid by-product gypsum to prepare bricks can not only make use of resources, save energy and protect the environment, but also reduce costs. [0003] There are also domestic research on fluorine gypsum brick making, such as national patent 201110353092.8, which provides a new t...
