• Replacing Sand in Concrete; Materials and Right Steel

    Jul 05, 2019· When considering economy and design, crushed sand can be used to partially or fully replace river sand from a concrete mix. Crusher Dust (Quarry Waste) In crusher dust, the particles (% finer than 150 microns) are commonly high, a major concern limiting its percentage replacement to a minimum with sand in a concrete mix.

  • What are the Materials for Replacement of Sand in Concrete

    Jun 08, 2017· Instead of disposing them in landfills, it can be best utilized as partial replacement to sand. In crusher dust, the particles (% finer than 150 microns) are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix. It can be replaced to the amount 25%. Its Avaiility is not a concern.
