dc.description.abstractThis study aims to investigate the fresh and hardened properties of self-compacting concrete (SCC) made with residue of masonry (RM) and concrete waste (CW). The RM was added as supplementary cementitious material (SCM), replacing ordinary Portland cement (OPC), in 25% by volume and the SCC mixtures were designed incorporating five increasing amounts of CW as recycled coarse aggregate (RCA) (0%, 25%, 50%, 75%, and 100%), which were compared with a reference SCC with a 100% OPC and natural coarse aggregate (NCA). Both fresh state (workability, passing ability and viscosity) and hardened state (compressive strength, indirect tensile strength, flexural strength, porosity and capillary suction) properties of SCCs were evaluated, including short and long-term evaluations. The results show that RCA generates a loss in the fluidity, flow rate, passing ability and filling capacity of SCC, presenting the greatest decrease of workability in high percentages (75% and 100%) of RCA. However, all the SCCs managed to be in the required ranges by the EFNARC. In the hardened state, the mechanical properties generally weakened with increasing replacements of RCA, but the reduction rate was minimal when the content of RCA did not exceed 50%, being 1.22% less at 360 days when compared to the reference mixture’s compressive strength. Finally, the presence of RM at long ages generated a positive effect on properties when compared to the reference SCC, which can be used to compensate the moderate strength reductions generated by low-to-medium replacement ratios of RCA leading to sustainable SCCs incorporating both residues (RM and CW) with similar performance than conventional SCCs.
