Dynamic compressive behavior of recycled aggregate concrete
Abstract The dynamic compressive behavior of recycled aggregate concrete (RAC) prepared with five recycled coarse aggregate (RCA) replacement percentages was experimentally studied at strain rates ranging from $ 10^{−5} $ to $ 10^{−1} $ $ s^{−1} $. The effect of strain rate, RCA replacement percentage and moisture condition on the compressive behavior of RAC was studied in terms of stress–strain curve, compressive strength, critical strain, and elastic modulus. The results show that the compressive strength and elastic modulus of RAC increased while critical strain exhibited no clear changes as the strain rate was increased. The compressive strength and elastic modulus of RAC generally decreased with increasing RCA replacement percentage under the same strain rate, while the critical strain increased. The compressive strength and elastic modulus of RAC tested in wet condition were lower than those tested in air-dry condition at all the strain rates.
