Flexural Behaviour Of Hybrid Fibre Reinforced Concrete Beams Containing Metakaolin And Nano Alumina

Abstract

In this research study, an effort has been made to examine the effect of incorporating hybrid fibres on the performance of concrete beams containing metakaolin and nano alumina. A total of nine beams were cast and tested for this study. The beams were 150 mm x 250 mm in cross section and 3000mm long. The specimens were tested under static loading condition. The performance of the beam specimens was assessed in terms of first crack load, deflection at first crack load, yield load, deflection at yield load, ultimate load, deflection at ultimate load, deflection ductility, deflection ductility ratio, energy ductility, energy ductility ratio. It is evident from the test results that inclusion of hybrid fibres appreciably improved the performance of concrete beams containing metakaolin and nano alumina in all fronts.
