The effect of Stone Powder content of dolomite manufactured sand on the cement Hydration

[摘要] In this paper, the effects of different stone powder content (5%, 10%, 15%, 20%, 25%) of dolomite manufactured sand on the workability and mechanical properties of cement were studied. The influence of stone powder content on the hydration products and microstructure of cement were studied by XRD, SEM. The results show that the workability and mechanical properties of cement can be improved obviously when the content of stone powder is less than 10%, and the influence of stone powder on hydration products and Microstructure of cement is small.
