摘要
通过X射线衍射分析、界面显微硬度的测试和扫描电镜观察 ,对掺矿渣微粉混凝土中胶凝体系的水化以及集料 -水泥石界面进行研究。试验结果表明 ,由于火山灰效应 ,矿渣微粉的掺入有效地减少了CH晶体在界面区的富集 ,改善了集料与水泥浆体界面薄弱区。随着矿渣微粉细度的增大 ,其效果更为明显。
The interface zone between aggregate and mortar for concrete containing ground granulated blast furnace slag(GGBS)have been investigated through the methods of XRD,SEM and the test of microhardness value.The results show that,GGBS significantly decrease the concentration of CH crystal at the interface zone owing to pozzolanic reaction.And so that,the weak interface zone is strengthened.This effect become more remarkable as the granule of GGBS more finer.
