Abstract: Stockpiles of glass fines generated from nonrecyclable glass packaging pose significant environmental and human health issues including groundwater and soil contamination. This study explores the suitability of glass fines for developing sustainable composites for building and construction. Glass-reinforced polymer (GRP) composites offer strength and sustainability for construction, but their flammability limits their use in fire-prone environments. This research focuses on the thermal stability, elevated-temperature mechanical properties, and fire properties of GRP composites. The research addresses polymer matrix flammability issues through ceramification, a process that transforms the flammable polymer into a thermally more stable binder. Although ceramification enhances the thermal performance of polymer composites, it reduces the flexural strength, tensile strength, and compression strength decreased by 53%, 60%, and 9%, respectively. This study also evaluates in situ thermomechanical and postheat mechanical performance of ceramified GRP composites exposed to temperatures ranging from 50°C to 250°C. The mechanical properties of the ceramified GRP composites at elevated temperature are relatively lower than measured for the same materials at ambient temperature. However, the mechanical properties of heat-exposed ceramified composites partially recovered upon cooling to ambient conditions. The ceramified GRP composite microstructure and material properties were analyzed via scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) analysis. The findings from this work revealed significant reductions in the flammability and smoke production propensities of ceramified GRP composites compared with their nonceramified counterparts, making them suitable for fire-prone infrastructure. The findings from this study revealed substantial reductions in heat release rates (by a factor of 5) and smoke production (by a factor of 19) upon ceramification of GRP composites compared with their nonceramified counterparts, highlighting their suitability for use in fire-prone infrastructure.
