摘　　要：论述了混合型细集料轻混凝土的微观结构及其转化特点 .着重对矿渣和粉煤灰掺合料对混凝土微观结构的影响、混合型细集料水泥砂浆在不同龄期水化产物的种类、形态、结构特征进行了探讨 .In this paper,the microstructures and its transformation characteristics of lightweight concrete with mixed type fine aggregates were discussed systematically.The effects of slag and fly ash were emphasised on the kind,morphology and microstructures of hydrates in mortars prepared with mixed type fine aggregates and cured at different time spaces.The influence of the transformation of microstructures on the property of concrete products was also evaluated.
