Technological properties of polymer concrete containing vinyl-ester resin waste mineral powder
Joanna Julia Sokołowska
AbstractThe 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.
