Cement preparation process capable of comprehensively utilizing industrial slag
The invention discloses a cement preparation process capable of comprehensively utilizing industrial slag. Three groups of samples, namely a group of blank samples and two groups of experimental comparison samples, are set. The blank group without slag is prepared from 95% of clinker and 5% of gypsum, the fineness is 3.4, the fracture resistance in three days is 5.2, the fracture resistance in twenty-eight days is 8.6, the pressure resistance in three days is 34.6, and the pressure resistance in twenty-eight days is 56.3. The experimental group of the first group doped with the slag comprises 75% of clinker, 5% of gypsum and 20% of slag, the fineness is 3.5, the fracture resistance in three days is 4.5, the fracture resistance in twenty-eight days is 7.5, the pressure resistance in three days is 30.0, and the pressure resistance in twenty-eight days is 50.1. The experimental group of the second group doped with slag comprises 65% of clinker, 5% of gypsum and 30% of slag, the fineness is 3.5, the fracture resistance in three days is 4.0, the fracture resistance in twenty-eight days is 6.4, the pressure resistance in three days is 26.5, and the pressure resistance in twenty-eight days is 46.5. The process has the advantages that the slag is added in the cement grinding section, the use amount of cement clinker is reduced, and the production cost is reduced under the condition that the cement quality is not influenced.
本发明公开了一种工业炉渣综合利用的水泥制成工艺，设置三组样品，一组空白样品，两组实验对比样品；不掺加炉渣空白组比例：熟料95％、石膏5％，细度:3.4、三天的抗折性：5.2、二十八天的抗折性：8.6、三天的抗压性：34.6、二十八天的抗压性：56.3；第一组掺加炉渣的实验组比例：熟料75％、石膏5％、炉渣20％，细度:3.5、三天的抗折性：4.5、二十八天的抗折性：7.5、三天的抗压性：30.0、二十八天的抗压性：50.1；第二组掺加炉渣的实验组比例：熟料65％、石膏5％、炉渣30％，细度:3.5、三天的抗折性：4.0、二十八天的抗折性：6.4、三天的抗压性：26.5、二十八天的抗压性：46.5。本发明具有水泥粉磨工段添加炉渣，降低水泥熟料的用量，不影响水泥质量的情况下降低生产成本的优点。
