Abstract
The invention discloses a building material with an ardealite matrix and a production method thereof. The building material with the ardealite matrix is produced from the following raw materials of, in parts by weight, 200-400 parts of ardealite, 1-10 parts of nanosilicon dioxide, 10-20 parts of rubber, 1-10 parts of multiwalled carbon nanotubes, 50-150 parts of gold mine tailings and 1-10 parts of water-retaining agent. The production method of the building material with the ardealite matrix comprises the steps of mixing the ardealite and the gold mine tailings evenly, and then ageing a mixture for a period of time; and stirring and mixing the nanosilicon dioxide, the rubber, the multiwalled carbon nanotubes and the water-retaining agent evenly, then mixing a mixture and the aged material, and packaging a mixture to obtain a finished product. According to the building material with the ardealite matrix and the production method thereof, raw material proportioning is reasonable and scientific, the production method is simple, operation is simple and convenient, and the obtained product has good application property, initial dry cracking resistance, water resistance and flexibilityand high bonding strength.
Description
technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a building material with a phosphogypsum matrix and a preparation method thereof. Background technique [0002] Phosphogypsum is a by-product of phosphate fertilizer production, and its emissions are increasing year by year. A large amount of phosphogypsum not only occupies land resources, increases the burden on enterprises, but also causes certain pollution to the environment; at the same time, it in turn restricts the development of the phosphate fertilizer industry. In order to effectively process and utilize phosphogypsum to reduce its pressure on the environment, the use of phosphogypsum as a building material has been developed to a certain extent. [0003] In the prior art, there are many reports on utilizing phosphogypsum to make putty for walls. For example, the "preparation method of a high-strength wall putty" of the patent number CN107337953A...
