Abstract
In the present study, the optimum dosage of fibres in Hybrid Fibre Reinforced Concrete (HFRC) and the
compressive strength, split tensile strength, stress strain characteristics and flexural behaviour of Hybrid Fibre
Reinforced Concrete (HFRC) with addition of glass fibre, polypropylene fibre and steel fibre was investigated. Cubes,
Cylinders and beams were cast by adding fibres to cement by volume fraction at various percentages like steel fibre (
0% ,0.4% ,0.8% ,1.2% ,1.6% ) , glass fibres ( 0% ,0.2%, 0.4% ,0.6% ,0.8% ) and polypropylene fibres ( 0% ,0.2%, 0.4%
,0.6% ,0.8% ).Compression and Split tensile tests were done on cubes and cylinders respectively to obtain the optimum
dosage of fibres, stress strain characteristics were found by testing the cylinders and flexural tests were conducted on
beams to determine the flexural behaviour of Hybrid Fibre Reinforced Concrete.
