  • Crushing characteristics of a recycled aggregate from waste

    Jan 30, 2018 A singleparticle crushing test was carried out for more than 170 recycled aggregates from waste concrete. Recycled aggregates were sieved into 30 and 40mm particle size groups, mainly consisting of mortar with 2–10 natural aggregates. At the initial loading of the single aggregate, its irregular surface
