Problems solved by technology

However, there are many disadvantages in these methods of processing liquid slag: as a Portland cement admixture, the dosage is small; the production of liquid slag steam-cured bricks is expensive; the production technology of silicon calcium potassium fertilizer is not mature enough, causing secondary pollution; Although the cost of producing mineral wool is low, due to the continuous change of coal quality and large fluctuations in calcium content, the viscosity of liquid slag changes greatly, which makes it difficult for the centrifuge to throw cotton at high speed, resulting in unstable quality, etc.

Abstract

The invention belongs to the technical field of building materials and particularly relates to ready-mixed plastering mortar prepared from industrial waste liquid slag. The ready-mixed plastering mortar consists of lime, pulverized fuel ash, natural sand, liquid slag powder, liquid slag aggregate particles, a thickener, an air entraining agent and a thickening time control agent. The ready-mixed plastering mortar prepared from the industrial waste liquid slag has the excellent performances of lime conversation, environmental friendliness, use of waste, high water retention rate, good operability and the like and has the characteristics that the plastering mortar is not cracked under the construction environments of dry air and relatively large wind speed in Xinjiang region.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a ready-mixed plastering mortar prepared by using industrial waste liquid slag. Background technique [0002] Fuel waste residue is one of the largest renewable resources in my country. The comprehensive utilization of fuel waste residue is a common concern at home and abroad, and it is also a need for energy conservation, environmental protection, promotion of energy conservation, and sustainable development. Industrial liquid slag is suspended and burned at 1450°C to 1600°C in a cyclone furnace, and becomes molten droplets, which are quenched by high-pressure water to form water-quenched slag when discharged. Industrial liquid slag can be used as aggregate instead of natural sand for concrete and mortar after proper drying, moisture removal and crushing. The water-quenched liquid slag has high chemical activity, and its main chemical composition is calcium aluminosi...
