    Manufactured sands can also contain significant quantities of rock dust. As natural sand deposits become depleted near some areas of metropolitan growth and viable sand sources non-susceptible to alkali–silica reactivity are consumed, the use of manufactured sands as a replacement fine aggregate in concrete is receiving attention.
