Structural Performance of Fibre Reinforced Ternary Blended Concrete Beams Containing Nano Alumina and Alccofine

Abstract

This research investigation focuses on evaluating the impact of introducing steel fibers on the effectiveness of concrete beams incorporating nano alumina and alccofine. The study involved the casting and testing of a total of six beams, each measuring 150 mm x 250 mm in cross-section and 3000 mm in length. These beams underwent testing under static loading conditions. The evaluation of beam performance encompassed various parameters, including the first crack load, deflection at the first crack load, yield load, deflection at the yield load, ultimate load, deflection at the ultimate load, deflection ductility, deflection ductility ratio, energy ductility, and energy ductility ratio. The findings derived from the test results unequivocally demonstrate a substantial enhancement in the performance of concrete beams containing nano alumina and alccofine when steel fibers are incorporated, evident across all measured criteria.
