between the factor levels, examining the mean plot and identify the LSD intervals. Ru presented similar performance than CNA, due to the overlapping between their corresponding bars. Rb presented better behavior in terms of resistance to fragmentation and compression than cementitious particles (Rc1 and Rc2). Rc1 and Rc2 did not show any similarity in any of the test results studied according to the statistical study. Determination of the RA composition Standard (UNE-EN 933- 11:2009) does not distinguish between masonry mortar and concrete particles. Based on these results, this differentiation could be helpful for better characterization of the RA
