  • Structural Concrete Prepared With Coarse Recycled

    An investigation of mechanical behaviour and elastic properties of recycled aggregate concrete RAC is presented. RACs were prepared by using a coarse aggregate fraction made of recycled concrete coming from a recycling plant in which rubble from concrete structure demolition is collected and suitably treated. Several concrete mixtures were prepared by using either the only virgin aggregates
