[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

Abstract
The invention relates to the field of building waterproofing, and specifically discloses phosphate rock slag waterproof plastering mortar, including dry powder mortar, and the dry powder mortar includes the following raw materials in parts by mass: 100 parts of cement, 220-280 parts of sand, and 30-70 parts of phosphate rock slag, 6-7 parts of inorganic siliceous structure self-waterproofing additive and 3-4 parts of repairing sphere; the inorganic siliceous structure self-waterproofing additive includes 68-78% active silicon dioxide, 8-16% alkali Soluble aluminum oxide, the rest are additives, including Fe 2 o 3 , NaCl and MgO; the repairing sphere includes at least two layers of concentrically arranged spherical crushing shells and connecting lines running through and fixed to each spherical crushing shell, and the inner side of the spherical crushing shell is filled with the self-waterproofing additive of the inorganic siliceous structure , the part of the connecting wire located between adjacent housings is in a contracted state. The invention realizes the application of the phosphate slag on the waterproof mortar, and improves the waterproof effect of the waterproof mortar.
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. [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, bec...
