Can machine-made sand be used in high-strength concrete?

The reduction of water to cementing material ratio ranging from 020 to 045 by mass can produce highearlystrength concrete Water to cement material ratio of 032 to 042 has been used to produce highearlystrength concrete whereas the use of wcm of 020 can produce veryhighearlystrength concrete 4 Higher Freshly Mixed Concrete
