Low-carbon cementing material and preparation method thereof
The invention provides a low-carbon cementing material and a preparation method thereof, and relates to the technical field of new materials. The method specifically comprises the following steps: uniformly mixing steel slag, blast furnace slag, fly ash, desulfurized gypsum, lime and an exciting agent according to a ratio, carrying out magnetic separation and screening on the uniformly mixed material, separating out an RO phase, conveying into a roller press, carrying out steaming treatment when cracks are generated on the surface of the material, introducing industrial flue gas after the treatment is completed, curing, conveying to an ultrafine mill, and controlling the fineness of the material to be greater than 500m < 2 >/kg, the low-carbon cementing material can be obtained. The raw materials used for preparing the low-carbon cementing material are mainly industrial solid waste and industrial flue gas, waste resources generated in industrial production are optimized and recycled, waste accumulation and pollutant emission are reduced, the cementing material with excellent performance can be prepared, and the method has the advantages of being low in production cost, low in carbon and environmentally friendly.
本发明提供了一种低碳胶凝材料及其制备方法，涉及新材料技术领域。具体包括将钢渣、高炉矿渣、粉煤灰、脱硫石膏、石灰和激发剂按比例混匀，将混匀后的物料经过磁选和筛分，分离出RO相后，传送进辊压机，当物料表面产生裂纹时，进行蒸湿处理，处理完成后通入工业烟气固化，传送至超细磨机，控制物料细度大于500m2/kg时，即可得到低碳胶凝材料。本发明制备低碳胶凝材料所用的原料主要为工业固废和工业烟气，将工业生产所产生的废弃物资源优化，回收利用，既减少了废弃物堆积和污染物排放，又能制备出性能优良的胶凝材料，具有生产成本低廉，制备方法低碳环保的特点。
