Properties of refractory bonding agent based on waste material
The fly ash disposal on open landfills poses significant risk to the environment. Sustainable solution for the pollution-prevention is reuse of fly ash in building materials. Building composites - high temperature bonding agents, in which fly ash is combined with refractory components is new option for reapplication of this waste material. In this study, investigated bonding agent was based on fly ash mixed with high-aluminate cement. Fly ash previously underwent mechanical activation. Mineral phase analysis of the composite by means of XRD was accented due to the changes occurring with increasing temperature. Processes taking place during composite thermal treatment from 20 up to 1100 oC were identified by means of DTA method. The leaching behaviour and potential environmental impact of hazardous elements were analyzed. Investigated fly ash-cement composite proved to have high physical and mechanical performances, but also good thermoinsulation characteristics. The overall results showed that application of the fly ash in high-temperature bonding agents is sustainable solution for managing this environmentally hazardous waste material.
