In the article, compressive strength, tensile and residual strength of fiber-reinforced concrete reinforced with basalt fibers were studied based on experiment. Basalt 10 mm 30 in length 0.017 thick added at 0.0%, 0.1%, 0.2%, 0.3%. The samples stored room temperature relative humidity above 75%, tested days 7 28. addition increased changed its brittle behavior to a more ductile one. When amount...
