An Investigation of Concrete Strength of Hybrid Construction Materials Under the Effect of Heat

The hybrid use of concrete and Glass Fiber Reinforced Plastic (GFRP) profiles in construction material technologies in recent years offers many new opportunities. Filling fresh concrete into GFRP profile allows for obtaining superior advantages compared to component materials. The purpose of this study is to investigate the change in the strength of concrete in hybrid material exposed to high temperatures. To this end, hybrid compressive samples were prepared by filling GFRP composite box profiles with concrete and plain concrete samples were prepared for comparison. The cubic samples were exposed to high temperatures at 25–200–400–600–800 °C. Strength losses of the plain concrete and the concrete in the hybrid material, which had the same dimensions, under the effect of heat were determined.
