In addition, IBA-FB was compared with IBA from moving grate (IBA-MG) combustion technology. The AABs formulated with IBA-FB (AAB-FB) and IBA-MG (AAB-MG) were also evaluated from a physicochemical, mechanical, and environmental perspective. The results revealed that specific surface area in IBA-FB hinders the retention of kneading water of fresh pastes, affecting the workability, consistency, porosity, and mechanical strength of AAB-FB. Moreover, the low calcium content of IBA-FB requires that the formulated AABs must be cured at higher curing temperatures to ensure the formation of (N,C) ASH gels, while the high calcium content of IBA-MG promotes the formation of CSH gels at room temperature. The compressive strength results demonstrated that AAB-MG (≈ 11 MPa) and AAB-FB (≈ 8 MPa) could be used for non-structural purposes.12 p.application/pdfengcc-by-nc-nd (c) Maldonado Alameda, Alex et al., 2022https://creativecommons.org/licenses/by-nc-nd/4.0/IncineracióMaterials de construccióResidusIncinerationBuilding materialsWaste productsinfo:eu-repo/semantics/article7274102023-03-31info:eu-repo/semantics/openAccess
