This experimental work aims to determine the mechanical strength properties of basalt fiber-reinforced concrete when natural river sand is replaced partially with manufactured sand. In this experiment natural river sand is replaced with manufactured sand by 0%, 25%, 50%, 75%, and 100%. A total of 30 cubes of size 0.15 x 0.15 x 0.15 meters and 30 cylinders of size 0.15 x 0.15 x 0.3 meters were casted respectively to check the compressive strength and tensile strength of the basalt fiber reinforced concrete when they age 7 days and 28 days. Also slump tests were conducted on each mix to determine the workability of the basalt fiber reinforced concrete. For ages, fiber-reinforcement has known to lead to improved tensile strength. In this research, basalt fibers of length 12mm, diameter 0.2mm and an aspect ratio of 60 are used by 0.25% of the total volume of concrete.
