【摘要】 根据不同离子的复合效应,研制了一种煤矸石WH-1高效复合活化剂,并初步探讨了在无熟料煤矸石粉注浆材料中的应用。研究结果表明,采用WH-1活化剂可有效激发煅烧煤矸石潜在的火山灰活性,显著提高煤矸石粉注浆材料早期强度,并可保证后期有较高的强度,能满足注浆材料对强度性能使用的要求。掺3%3d和28d强度可分别达到3.5MPa和9.4MPa。更多还原

【Abstract】 According to compound effect of different ion,the preparation of WH-1 highly activator to burnt gangue was studied.Also,its application in grouting materials was studied.The experimental results show that the activator can effectively activate gangue activation to increase the initial strength obviously.When 3% of the activator was added,the 3 d strength can reach to 3.5 MPa,and also assure that the material has higher late strength,the 28 d strength can reach to 9.4 MPa,which could satisfy the strength-performance demanding for grouting.更多还原
