Abstract

The invention belongs to the field of environmental protection, and in particular relates to green and environment-friendly masonry mortar, consisting of the following raw materials in percentage by weight: 20-25% of phosphorus slag powder, 15-20% of modified alum sludge, 8-12% of cement, 0.01-0.05% of a tackifying water retention agent, 0.2-1% of a thixotropic lubricant, 0.02-0.08% of an intensity excitant, 0.01-0.1% of a dispersant, and the balance of river sand. The green and environment-friendly masonry mortar provided by the invention ingeniously makes use of a coagulation accelerating property of an aluminum-containing compound in the alum sludge, and the alum sludge is used together with the phosphorus slag powder to ensure that the masonry mortar provided by the invention has an appropriate coagulation time. The environmental protection pressure and the waste discharge burden of a waste discharge enterprise can be significantly reduced, and the ecological environment can be improved.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a green environment-friendly masonry mortar. [0002] technical background [0003] Phosphorus slag is an industrial by-product of the production of yellow phosphorus by the electric furnace method. For every 1 ton of yellow phosphorus produced, about 8-10 tons of phosphorus slag are produced. The granular phosphorus slag after rapid cooling is mainly of glass structure. If the high-temperature molten slag is naturally cooled slowly, it will become massive phosphorus slag with high hardness and low activity. The chemical composition of phosphorus slag is CaO, SiO 2 Mainly, accounting for 90%, due to P in phosphorus slag 2 o 5 , F - Harmful components such as phosphorus can delay the setting and hardening of cement, which restricts the popularization and application of phosphorus slag in cement-based materials. [0004] Alum is widely used in chemical, food, ...
