Phosphorus slag waterproof plastering mortar and mortar plastering waterproof construction method

Abstract

The invention relates to the field of building waterproofing, and particularly discloses phosphorus slag waterproof plastering mortar, which comprises dry-mixed mortar, and the dry-mixed mortar comprises the following raw materials in parts by mass: 100 parts of cement, 220-280 parts of sand, 30-70 parts of phosphorus slag, 6-7 parts of an inorganic siliceous structure self-waterproof additive and 3-4 parts of repair spheres; the inorganic siliceous structure self-waterproof additive is prepared from the following components in percentage by weight: 68 to 78 percent of active silicon dioxide, 8 to 16 percent of alkali-soluble aluminum oxide and the balance of auxiliaries, and the auxiliaries comprise Fe2O3, NaCl and MgO; the repairing sphere comprises at least two layers of spherical crushing shells which are concentrically arranged and connecting lines which penetrate through and are fixed to the spherical crushing shells, the inner sides of the spherical crushing shells are filled with the inorganic siliceous structure self-waterproof additive, and the parts, located between the adjacent shells, of the connecting lines are in a contraction state. The application of the phosphorus slag in the waterproof mortar is realized, and the waterproof effect of the waterproof mortar is improved.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, and in particular relates to a phosphorite slag waterproof plastering mortar and a mortar plastering waterproof construction method. Background technique [0002] Mortar is one of the most widely used building materials in construction engineering, and it is widely used in masonry and plastering of buildings. [0003] The mortar waterproof layer is also called the rigid waterproof layer. The waterproof mortar is mainly mixed with various waterproof agents in the cement mortar to improve the waterproof performance of the mortar.

AI Technical Summary

Problems solved by technology

[0004] At present, phosphate slag is an industrial waste slag produced in the process of producing yellow phosphorus by electric furnace method. It is a melt with calcium silicate as the main component obtained when yellow phosphorus is produced by electric furnace method. After quenching, it is granular Phosphorus slag from chemical electric furnace, because the phosphorus content in phosphate slag is too high and the activity is reduced, this kind of industrial waste slag has not been developed and utilized on a large scale. Usually, 8 to 10 tons of phosphate slag are produced for every ton of yellow phosphorus produced.

Phosphate slag has been widely used as a concrete admixture in the prior art, but there is still little research on the application of phosphate slag in waterproof mortar
