Abstract text:
. Polymer concrete with epoxy resin, fly ash and river aggregate has been prepared in the study. All components had varied dosages in the mix. Fly ash was used as filler in different dosages (from 6.4 to 25%). The resin dosage was between 12.4% and 23%. Aggregates varied between 30% and 43%. The mechanical properties such as: compressive strength, flexural strength and split tensile strength were determined. The dosages of components influenced the mechanical properties. A high epoxy resin dosage improved the compressive strength. The increase of fly ash dosage generally improved all mechanical properties, but the results were related to the dosages of epoxy resin and aggregates. The maximum values of mechanical strength were obtained for a medium fly ash dosage, but in strong relation with epoxy resin dosage.
Key Words:
