Experimental verification of utilization of fly ash from the flue gas denitrification process as a filler to epoxy patching mortar

Paper in proceedings (conference paper)

The paper deals with the possibility of using of the fly ashes, which is formed by the high-temperature combustion and contaminated by a denitrification process. The main aim of this work is to verify the application of these fly ashes as a filler for polymer patching mortar to achieve as the ecological and the economical requirements, as it is the most considered theme of a present. The maximum possible proportion of the fly ash is determined by experimental testing of the physical and mechanical properties of the epoxy patching mortar. Bulk density and strength properties are determined and on the basis of the test results of the flexural and compressive strength the possibility of replacing the commonly used filler, quartz sand Dorsilit, by the contaminated fly ash is assessed. Furthermore, application of X-ray tomography (CT scanner) for distribution of the fly ash particles and for pore-related characterization in the epoxy matrix was explored in this paper.
