Abstract
This study presents the results of an experimental investigation that evaluates the effect of recycled concrete aggregate replacement level on the fracture energy of concrete. This study includes five mixes with 0, 30, 50, 70, and 100% recycled concrete aggregate as a coarse aggregate replacement. This experimental program consisted of 20 fracture beams to study the fracture behavior of concrete. The experimental fracture energies were compared with the fracture energy provisions of different design codes and also different analytical equations. Furthermore, statistical data analyses (both parametric and non-parametric) were performed to evaluate whether or not there is any statistically significant difference between the experimental fracture energies of different mixes. Results of these statistical tests show that the mix with higher level of recycled concrete aggregate replacement level has lower fracture energy.
