掺硅粉水泥与硅质集料界面结构的初步探讨

STRUCTURES OF INTERFACE BETWEEN CEMENT MIXED WITH SILICON FUME AND SILICON AGGREGATE

通过一系列实验数据和曲线说明,掺硅粉水泥与集料的界面结构有所变化,并闸述了变化的原因。实验结果表明:掺硅粉水泥与集料胶结的粘结强度高于硅酸盐水泥与集料胶结的粘结强度;界面区的最薄弱层并不在界面表层,而是在距界面十几微米处。

The paper illistrated that through a series of experimental data and curves, the interface for the cement mixec with silicon fume and the aggregate is changed and the cause of change is preliminarily explained; the binding strength of the cementing for the cement mixed with silicon fume and the aggregate is higher than that of the silicate cement and the aggregate is obtained; and also the conclusion that the weakest layer of the interface region does not exist at its superficial coat but at the place that is at a distance of ten odd μm from the furface.
