The research paper focus on “Study of Concrete Behavior with the Addition of Basalt Fibers”, works were carried out on experimental investigation of basalt fiber concrete. The present paper focus on the comparison of the compressive strength, tensile strength, flexural strength of plain concrete and concrete using basalt fibers of M30 grade concrete. Various types of fibers such as steel, carbon, polypropylene, glass are used to improve the tensile and flexural strength of concrete. Based on the laboratory experiments on basalt fiber concrete, cubes, beams and cylindrical specimens have been casted with different proportions of 0%, 0.5%, 1.0%, 1.5%, and 2.0% to the weight of the cement.The results obtained shows a considerable increase in the compressive strength, tensile strength, flexural strength of basalt fiber concrete at 28 days to that of the plain concrete.

Keywords : Basalt fibers, compressive strength, tensile strength, flexural strength.
