Effect of Aggregate Percentage on the Fracture Parameters of Steel Fibre Reinforced Recycled Aggregate Concrete
Frajitha Franklin | Jayaprakash Jain K. G.
Abstract: In this study, fracture parameters are determined by conducting four point bending test on notched beams. Beams with varying percentage of 25, 50 and 75 % of recycled aggregate is been used with a constant percentage of steel fibre with an initial notch depth. The peak load of the specimen with lesser percentage of recycled aggregate was higher. Deflection also decreased with increasing recycled aggregate percentage. It is found that fracture toughness is reducing with increasing percentage of recycled aggregate. The other two parameters namely fracture energy and energy release rate is also reducing with increasing percentage of recycled aggregate. So the presence of recycled aggregate actually affects the behavior of beam.
