Technological properties of polymer concrete containing vinyl-ester resin waste mineral powder

The aim of the presented research was to assess the possibility of using waste mineral powder (remaining after preparation of aggregates for mineral-asphalt composites) as a component of polymer concrete with vinyl-ester resin used as the binder. The evaluation was done in terms of chosen technological properties, namely: consistence and temperature changes during setting of polymer mix. The first part of the paper contains material characteristics (chemical composition, particles size distribution, specific surface area) of mineral powders – both commonly used quartz powder and waste mineral powder – applied into polymer concrete as the finest fraction of aggregate. The second part of the research was focused on characteristics of setting of micro-mortars with vinyl-ester resin modified with the waste powder and consistence of concrete mixes prepared with use of those micro-mortars. Taking into consideration obtained data, author determined the optimal compositions of concrete with vinyl-ester resin and waste mineral powder of technical properties not worse than in case of regular (non-modified) one, but at the same time definitely more ecological.
