What is it about?
The aim of the research was to test the ability of vinyl-ester concrete containing waste powder to resist chemical attacks of sulfuric acid and sodium hydroxide. Tested composites contained mineral dust remaining after preparation of aggregates for mineral-asphalt composites. It was experimentally confirmed that from the point of view of chemical composition, granulometry, specific surface area, and density, the waste dust appeared to be a good substitute for commercial quartz powder used in polymer concrete. The evaluation of chemical resistance of polymer concrete with waste dust was done in terms of mass loss and change in compressive strength of composite after its exposition to aggressive media. The tests were performed according to the modified method described in guidelines for the precast elements production. Analysis of test results showed that even the high substitution of quartz powder with waste mineral dust (up to ~85%) in vinyl-ester concrete is possible and such composite presents high mechanical properties (though in some cases it requires using larger amounts of polymer) – not much worse than in case of non-modified composites.
