As shortage of natural medium/coarse sized sand resources, preparing concrete with extra fine sand having extensive sources is the only way to develop concrete industry sustainably. Application of large-volume extra fine sand in concrete was studied. The results show that mixing nature medium/coarse sized sand in extra fine sand can not only improve the workability and strength of concrete, but also reduce the production cost of concrete effectively.
