Abstract: The use of High Strength Concrete (HSC) is incérasse rapidly. From the study of expérimental investigation, It has been observe that HSC is relatively brittle material. Fibres are added to improve its ductility. Experimental study is carried out to assess comparative study in between two types of fibres for mechanical properties of high strength fibre reinforced concrete (HSFRC) of grade M80. In addition to normal materials, silica fume, fly Ash and two types of fibres viz. polypropylene fibre and sound crimped steel fiber, are used. The content of silica fume and fly ash is 5% and 10% respectively by weight of cement. Water to cementitious material ratio was 0.25. Mixes are produced by varying types of fibres and for each type of fibre its volume fraction is varied from 0.5% to 4.0 % with an increment of 0.5% by weight of cementitious materials. 51 specimens each of cubes (100Χ100Χ100mm), cylinders (100Χ200mm) and prisms (100Χ100Χ500mm) are tested to study the effect type and volume fraction of fibres on compressive strength, split tensile strength and flexural strength of HSFRC. The results indicated significant improvement in mechanical properties of HSFRCH
