Tailing powder wet-mixed plastering mortar
The invention discloses a tailing powder wet-mixed plastering mortar which is prepared from the following raw materials in mass percent via wet mixing: 5-10% of tailing powder, 60-75% of tailing manufactured sand,10-15% of cement, 0.5-1.5% of a plastic stabilizer, 0.1-0.5% of a retarder and the balance of water. The tailing powder wet-mixed plastering mortar can be used for effectively improving the resource recycling rate of the tailings so as to turn the tailings into wealth; tests show that the tailing powder can be used for improving the peaceability of mortar, improving the bonding strength of the mortar, reducing the shrinking percentage of the mortar, effectively preventing the mortar from cracking and hollowing, effectively reducing the consistency loss of the mortar and prolonging the construction operation time of the mortar. The mortar is low in production cost, stable in quality and long in construction operation time; by adopting a wet mixing technology, the fine aggregates such as the tailing manufactured sand and the like do not need to be dried, so that the energy-saving and environment-friendly green concept is met.
