Enhancing fire resistance in reinforced concrete members through the application of hybrid fiber-reinforced polymers

ABSTRACT

In this study, the reinforcement of reinforced concrete (RC) components with a combination of aramid and basalt fibers to enhance the overall structural performance and durability. In this empirical investigation, we meticulously assess the strength of concrete components both with and without the incorporation of fibers, while also scrutinizing the strengthening of concrete components exposed to the detrimental effects of fire. The concrete components under scrutiny encompass cubes, prism cylinders, and other specimens constructed from standard concrete, as well as concrete components enveloped with basalt fiber and aramid fiber. This research endeavor adopts the M20 mix for the concrete specimens, which are meticulously cast and cured in order to facilitate the subsequent testing of compressive strength (CS), flexural strength (FS), and split tensile strength (STS). The potency and fire-resistant properties of the standard concrete specimens are juxtaposed with those of the concrete specimens enveloped with basalt fiber and aramid fiber, which are then subjected to varying temperatures. Ultimately, the culmination of this project consists of the presentation of the findings and the comprehensive elucidation of the details derived from the aforementioned experiments.
