摘   要:为了解决电解锰渣活性较差、利用率较低的问题,对电解锰渣进行了机械-化学耦合激发,研究了不同激发方式对掺电解锰渣水泥净浆抗折、抗压强度的影响,并进行了SEM、XRD、FTIR分析。结果表明:最佳球料比和球磨时间分别为15∶1、20 min;掺入适量经过球磨处理的电解锰渣可以显著提高试件的抗折、抗压强度;Ca(OH)2和无水Na2SO4激发剂的搭配使用对电解锰渣活性的激发效果比二者分别单独使用的好,最佳n(Ca(OH)2)∶n(Na2SO4)为2∶3,总掺量为1.5%,此时,试件内部结构致密、28 d水化程度较高,28 d抗折、抗压强度分别较基准组提高了43.2%、24.7%。 Abstract: In order to solve the problems of poor activity and low utilization rate of electrolytic manganese slag, the mechanical and chemical coupling excitation method was conducted on electrolytic manganese slag. The effects of different excitation methods on the flexural and compressive strength of cement paste mixed with electrolytic manganese slag were studied, and SEM, XRD and FTIR analysis were conducted. The results show that the optimal ball to powder weight ratio and ball milling time are 15∶1 and 20 min, respectively. Adding an appropriate content of electrolytic manganese slag after ball milling treatment can significantly improve the flexural and compressive strength of the specimen. The combination of Ca(OH)2 and anhydrous Na2SO4 as activators has a better activation effect on the activity of electrolytic manganese slag compared to both as activators alone, and the optimal molar ratio of  Ca(OH)2 to anhydrous Na2SO4 is 2:3, and the optimal total content is 1.5%. At this time, the internal structure of the specimen is dense, and the 28 d hydration degree is high, and the 28 d flexural and compressive strength are increased by 43.2% and 24.7% compared to the reference group, respectively.

(1)电解锰渣的最佳激发方式为机械-化学耦合激发,对应的具体参数如下:球料比为15∶1、球磨时间为20 min、n(Ca(OH)2)∶n(Na2SO4)为2∶3、激发剂总掺量为1.5%。此时,试件的28 d抗折、抗压强度分别较基准组提高了43.2%、24.7%。
(2)Ca(OH)2作为激发剂更有利于提高掺电解锰渣水泥基材料的抗折强度,Na2SO4作为激发剂更有利于提高掺电解锰渣水泥基材料的抗压强度。
(3)机械-化学耦合激发提高了胶凝体系的水化反应程度,加快了Ca(OH)2的消耗和C-S-H、C-A-S-H、N-A-S-H凝胶的生成,使试件内部结构变得更为致密。
