Abrasion Resistance of Manufactured Sand (MS) Concrete and Its Influence Factors

The feasibility of using MS to replace river sand (RS) in concrete pavement has been widely concerned by scholars, however the abrasion resistance of MS concrete pavement serves as a major factor restricting application. Published literature shows huge potential of MS as a replacement of natural fine aggregate. A detailed overview of published literature on property of MS and influencing factors on abrasion resistance of MS concrete is being presented. Regarding the characteristics of MS, the granular shape is characterized by irregular shape, multi-angle and large aspect ratio, the gradation shows a phenomenon of less in the middle and more on both ends, and MS contains high content of stone powder and little mud powder. The influencing factors include mix ratio, lithology, stone powder, admixture, polymer, etc. Among them, stone powder has attracted the attention of many scholars. Nevertheless, few related studies exist at present, source selection and in-depth research merit consideration.
