This article presents an attempt to evaluate the mechanical properties such as the flexural strength and impact strength of polymer concretes based on unsaturated polyester resin reinforced with milled car windscreen waste glass and quartz sand. A set of five samples was prepared with a stable volume content of resin at 30% and varying proportions of milled glass from recycled car windscreens and quartz sand. The materials were tested in static and dynamic (Charpy) bending conditions. Based on the collected data, it was found that the most favorable properties were obtain by the polymer concrete with milled glass, and milled glass and sand (volume ratio 1:1). It is predicted that the developed materials can be successfully used in the production of paving slabs as well as prefabricated garden and road accessories. This would enable the disposal of troublesome waste, which is car windscreens, to produce high-quality products with a long service life.
