Abstract: Concrete is one of the oldest construction materials in the world. newlineDevelopment of concrete is made constantly by varying the material of the newlineconcrete. The improvement in concrete is obtained by addition of materials newlinesuch as fibre. The concrete tends to improve its tensile properties newlinetremendously. Various research works are carried out to find the optimum fibre newlinecontent. Steel fibre are mostly used to improve the strength. There are different newlinetypes of steel fibre such as hooked, crimped and micro steel. The main newlinedisadvantage of presence of steel fibre is corrosion. The micro steel fibre is newlinesmaller in size when compared to hooked or crimped fibre. The smaller size newlinehelps in easy dispersion. The concrete matrix has discontinuity in fibre. This newlinereduces progression of corrosion. Even the fibre presents in the outer surface newlinecorrode, the fibre in inner surface remains protected by the concrete matrix. newlineThe basalt fibre also shown tremendous increase in post crack behaviour. The newlinebasalt fibre is a inert material which prevents deterioration of concrete. newlineThe first phase of this project study is to determine the performance newlineof the fibre-reinforced concrete with a volumetric fraction of 0.25%, 0.5%, newline0.75% and 1%. Two fibre used are micro steel and basalt. A detailed study on newlinethe effect of fibre in reinforced concrete is carried out. The compressive newlinestrength, split tensile strength, flexural strength and impact strength are newlineselected as mechanical performance indicators. The compressive strength of newlinethe fibre reinforced concrete improves up to a volumetric fraction of 0.75% and newlinereduces at 1% volumetric fraction for both fibres. The tensile properties such as newlinesplit tensile and flexural strength increases with increase in the fibre content. newlineThe highly performed fibre-reinforced concrete is used as functionally graded newlineconcrete. newline
