摘要
采用XRD、DTA、SEM和测定水化结合水量等方法研究了高钛高炉渣在混凝土中的作用机理。结果表明:高钛高炉渣掺入混凝土中,有利于混凝土形成细观自紧密堆积体系、加速水泥水化速率、发生"二次反应",促进混凝土强度发展;高钛高炉渣的"二次反应"一般发生在水化后期,掺入适量激发剂能在一定程度上加速高钛高炉渣的"二次反应"。
The action mechanism of high titanium blast furnace (BF) slag in concrete was studied by XRD、 DTA、 SEM and determining the combine-water amount of hydration process. The results show that the high titanium blast furnace slag mixed in the concrete can help concrete to form microcosmic compact deposit, accelerate the hydration rate of cement, produce 'the second reaction', advance the strength of concrete. 'The second reaction' of high titanium blast furnace slag takes place at the later stage of hydration. When mix right amount of exciting agent in high titanium blast furnace slag, it can accelerate the 'the second reaction' to progress.
