| Abstract: | The typical preparation processs of manufactured sand and its utilization in engineerings was introduced,and the factors which influenced the sand quality in preparation processs was analysed.Furthermore,a bridge engineering in western China was set as an example,the method of preparation of concrete for the pile position was illustrated.Meantime,the compressive strength,the impermeability,the resistance to chloride penetration,and the sulfate corrosion resistance coefficient for concrete specimens was tested,and the effect of stone dust content on concrete properties was analysed in this work.The achievement were expected as a guide for the similar structures. |
