Abstract
2021.1.20 The mechanical properties of manufactured sand concrete are related to the physical properties of fine aggregate with different lithologies. With the increase of fineness modulus or stone powder content, the peak stress and peak strain of manufactured sand concrete show a trend of first increasing and then decreasing.
