Abstract

The invention belongs to the energy-saving and environmental-friendly field and particularly relates to energy-saving and environmental-friendly masonry mortar. The energy-saving and environmental-friendly masonry mortar comprises the following materials in percent 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-retaining agent, 0.2%-1% of aluminum-magnesium silicate, 0.02%-0.08% of a strength exciting agent, and the balance of river sand. The energy-saving and environmental-friendly masonry mortar has the advantages that by ingenious utilization of the coagulating property of aluminum-containing compounds in the alum sludge and common use of the alum sludge and the phosphorus slag powder, the coagulation time is proper; and the environmental protective pressure and waste discharge load of a waste discharge enterprise can be obviously relieved, and the ecological environment can be improved.

Description

technical field [0001] The invention belongs to the field of energy saving and environmental protection, and in particular relates to an energy-saving and environment-friendly masonry mortar. technical background [0002] Phosphorus slag is an industrial by-product when yellow phosphorus is prepared by electric furnace method. For every 1 ton of yellow phosphorus produced, about 8-10t of phosphorus slag is 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. [0003] Alum is widely used in chemic...
