Abstract EN
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 (as reference) or 30% coarse recycled aggregate replacing gravel and by using two different kinds of cement.
Different water-to-cement ratios were adopted ranging from 0.40 to 0.60.
Concrete workability was always in the range 190–200 mm.
Concrete compressive strength, elastic modulus, and drying shrinkage were evaluated.
Results obtained showed that structural concrete up to C32/40 strength class can be manufactured with RAC.
Moreover, results obtained from experimentation were discussed in order to obtain useful information for RAC structure design, particularly in terms of elastic modulus and drying shrinkage prediction.
