摘要: Abstract This paper aims to evaluate the material properties of polymer concrete for repair runways. Test specimens were prepared under room temperature conditions (25 °C), and mixing ratios between aggregates epoxy resin 90:10, 85:15, 80:20, 70:30 by weight. The real-time degree cure was measured a dielectrometry sensor. Compressive flexural tests carried out, in order measure any property changes according ratio. thermal expansion each attached FBG fiber optic sensors, with variation from −25 °C 85 °C controlled environment chamber. measurements used estimate coefficient concrete. Based on mechanical properties, serviceability as runways investigated.
