Possibilities of filling polymeric anchors with secondary raw materials with effect on price and final parameters

Original language description

Within this work different types and amounts of the suitable secondary raw materials as filler to polymer anchor were tested as possible substitution of currently used primary fillers. Physical and mechanical properties of the fast curing anchoring material based on epoxy resin were determined. The aim of this research was to achieve the anchor containing high amount of the secondary raw materials with the same or better final properties than reference anchors. As the suitable secondary raw materials, waste transparent packaging glass (TPG), high temperature filter fly ash (HTF) and circulating fluidized bed combustion filter fly ash (FCA) contaminated by the selective non-catalytic reduction (SNCR) denitrification technology were chosen. To use as much as possible suitable secondary raw materials to limit its landfilling and save the price for the expensive epoxy resin was verified. It was found out that the developed polymer anchors containing up to 45% contaminated filter fly ash shows better physical and mechanical properties than the reference anchors utilizing only primary materials. This ascertainment should make the production of polymer anchor both environmentally and financially less demanding. Furthermore, the microstructure of the developed anchors was investigated by the CT tomography, and it was found out that even after the pull-out force of 120 kN there was no deterioration of the polymer anchor, and a filler in the form of fly ash (HTF, FCA) and waste packaging glass (TPG) was evenly distributed in the polymer mass (EPB1).
