    Why Smartcrushers SmartCrusher bv Concrete recycling

    The sand and gravel retrieved from concrete rubble by using the SmartCrusher, is better in new concrete than new sand and gravel. An increase in strength by 25% is the rule rather than the exception. In addition, this extra strength with SC sand and gravel can be used to reduce approximately 15% cement (and thus it reduces CO 2 by 15%).

    Effect of Fineness of Sand on the Cost and Properties of

    The net cost of Concrete reduces when FM of sand increases. It reduces by about 6.5% for an increase of FM from 2.0 to 3.0. As the fineness modulus of Sand increases, the Cost/Benefit Ratio reduce by a very large factor. This is 29% when FM changes from 2.0 to 3.0. That means we can get large advantage by using concrete having Coarse Sand.
