| Abstract: | The stone powder content of the manufactured marble sand used in Jinping I Hydropower Station exceeds the re-quirement of the regulation. There are too many rusty aggregate, rusty stone, marble and slate aggregate in the coarse aggregate. On the basis of the study on concrete property, the content control standard of various particles is recommended. The quality of the aggregate is improved through optimizing the manufacturing technique, which can ensure the property of the concrete and save the cost. So, the concrete quality of Jinping I Hydropower Station is guaranteed. |
