Abstract: Concrete having characteristics strength of more than 65 MPa is categorized as high-strength concrete according to IS 456. The high strength concrete is more brittle compared to ordinary strength concrete and inclusion of fibers can increase the ductility of concrete. In the present study, high strength self-compacting concrete of characteristic strength of 90 MPa was developed as per the guidelines of EFNARC. Basalt fibers were considered to investigate its influence on the properties of high strength self compacting concrete. Three aspect ratios of 230, 530 and 600 were considered and are added in proportions of 0.1% and 0.4% by volume of concrete. The properties of concrete determine were fresh and hardened. Fresh properties such as slump flow test, V-funnel test, V-funnel T5 minutes and L-box test were determined as per EFNARC. Also, hardened properties such as compressive strength, split tensile strength and flexural strength were determined. A typical comparison on the effect of aspect ratio of basalt fibers and the dosage on the properties of concrete were determined. From the results, the optimum dosage of fibers was determined.
