| 摘要: |
| 采用XRD,DTA,SEM和水化结合水量测量等方法研究了高炉钛渣提高混凝土抗压强度的作用机理.研究表明:磨细的高炉钛渣微粉掺入到混凝土后,可以加速水泥水化速率,产生"二次反应",促进混凝土形成细观自紧密堆积体系,促进混凝土强度进一步发展;掺入适量激发剂能在一定程度上加速高炉钛渣的"二次反应". |

| Abstract: |
| The strengthening mechanism of titanium contained blast furnace slag in concrete was studied by XRD,DTA,SEM and by determining the combined water content of hydration.The experiment results show that if the ground fine titanium contained blast furnace slag is mixed in concrete as blending material it can accelerate the hydration rate of cement,produce "the secondary reaction",help concrete form microcosmic self-compact system,increase the concrete strength.When mixing right amount of activating agent in con... |
