Fluidised-bed incineration bottom ash as the sole precursor of alkali-activated binders: A comparison with bottom ash from grate incinerators

The novel formulation of alkali-activated binders (AABs) using incineration bottom ash (IBA) from fluidised bed (FB) combustion technology as a sole precursor was assessed. In addition, IBA-FB compared with IBA moving grate (IBA-MG) technology. AABs formulated (AAB-FB) and IBA-MG (AAB-MG) were also evaluated physicochemical, mechanical, environmental perspective. results revealed that specific surface area in hinders the retention kneading water fresh pastes, affecting workability, consistency, porosity, mechanical strength AAB-FB. Moreover, low calcium content requires must be cured at higher curing temperatures to ensure formation (N,C)ASH gels, while high promotes CSH gels room temperature. compressive demonstrated AAB-MG (≈ 11 MPa) AAB-FB 8 could used for non-structural purposes.
