Concrete specimens were mixed with chopped basalt fiber and casted, the strength checked on 7th, 14th and 28th day and evaluated based on flexural strength, compression strength. The addition of basalt fiber in the specimens showed significant effect where the compressive strength decreased while the flexural strength increased.
