Shear Strength and Fracture Toughness of Steel Fibre Reinforced Concrete with Industrial Wastes
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
This Paper gives a review of research works performed on Steel Fibre reinforced concrete, the effects of copper slag, Ground Granulated Blast furnace Slag (GGBS) and Metakaolin on concrete when they are used to replace the cement and sand content in concrete. The project focuses on fracture toughness and shear strength properties of steel fibre reinforced concrete with industrial wastes. In this study, M30 grade concrete is used. The cement is replaced up to 20% with Metakaolin and Ground Granulated Blast furnace Slag (GGBS) in equal proportions. The river sand used as fine aggregate is replaced with copper slag up to 60%. The hooked end steel fiber addition is kept constant as 3% by weight of binder content. Specimens of size 250×50×50 mm are used with notch of constant width 3mm with different notch depth ratios of 0.1, 0.2, 0.3 and 0.4. The fracture toughness is determined by using three point and four point bending test. For shear strength L-shape specimens of size (150×150×150 mm – 150×90×60 mm) are used. The results are obtained and compared with the tesults of ordinary concrete mix.
