Behaviour of High-Performance Fibre Reinforced Concrete Composite Short and Slender Columns under Uniaxial Compression

This paper describes the experimental studies carried out on the RC short and slender columns of bagasse ash blended HPC with influence of steel fibre (STF) and polypropylene fibre (PPF)are presented. The concrete was considered for M60 grade as recommended by P.C.Aitcin. The mix included both free steel fibre and polypropylene fibre, and furthermore the hybridization of steel fibre and polypropylene fibre at a total volume fraction of 1.0% by volume of concrete with 10% bagasse ash as a substitution of cement. Behaviour of eleven HPFRCC of each short and slender column with steel fibre, polypropylene fibre and hybrid fibres was examined. The behaviour of each column was assessed and presented with respect to load carrying capacity. The numerical studies were done using ABAQUS 6.9 to validate the experimental results.
