| description | Incorporating fibers into reinforced cement concrete significantly enhances the structural suitability under impact and seismic loads by augmenting the stiffness and energy-saving efficiency of the material. Concrete cracks activate the vital fiber behavior called the bridge effect, enhancing the structure's strength and ductility. Since adding fibers to the concrete mix does not reduce water content but rather impairs workability due to the friction generated between fibers and the mixed paste, resulting in fiber balling. This phenomenon diminishes the performance of fiber-reinforced concrete. Adequate distribution and dispersion of fiber in the mix increases the strength and thus avoids the occurrence of fiber balling. According to reviews, nylon fiber dosages ranging from 1.5% to 3% result in effectively performing nylon fiber-reinforced concrete, which exhibits sufficient strength, durability, and flexibility. In this study, experiments have been conducted to better understand the behavior of nylon fiber-reinforced concrete at elevated temperatures by using 17 mm, 25 mm, and 50 mm nylon fiber at 1.5% and 3% dosages. When comparing different temperatures, such as normal temperature condition and elevated temperature conditions (400 °C and 800 °C), always 1.5% dosage has shown the best result for compressive strength and split tensile strength. Here, 3% dosage of nylon fiber has shown reduced mechanical strength because of the effect of fiber balling. As far as compressive strength has taken into account in three temperature cases (normal temperature, 400 °C and 800 °C), 1.5% dosage and 50 mm length of nylon fiber has achieved the most effective strength result. Besides, when split tensile strength has been concerned, 1.5% dosage and 25 mm length of nylon fiber have given the best result compared to other lengths and dosage in three temperature conditions. |
