COMPREHENSIVE STUDY OF HIGH STRENGTH FIBER REINFORCED CONCRETE UNDER PULL OUT STRENGTH

The present work deals with an experimental investigation and results obtained on the high strength steel fiber reinforced concrete. The effects of these fibers on workability, density, and on various strengths of high strength concrete (M60 gr ade concrete) are studied. Present paper emphasises on the Pullout strength of concrete. The fiber content varied from 0.5 to 5% by weight of cement at the interval of 0.5 %. Concrete cubes of 150x150x150 mm with 16mm tor bar embedded in concrete at the centre of the cube were casted. All the specimens are water cured and tested at the age of 7 and 28 days. Workability of wet mix is found to be reduced with increased fiber content. Super plasticizer is used to increase workability.
