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...

Structural strengthening is needed in buildings that experience a decrease serviceability, inappropriate quality of existing concrete, and unexpected natural events such as earthquakes. One method has been widely used for structural external restraint using synthetic Fiber Reinforced Polymer (FRP). External restraints on concrete can significantly increase the strength ductility concrete. The u...

In this research, effect of opening on the buckling of FMLs (Fiber Metal Laminate) is studied. Samples are made of a laminate, epoxy resin reinforced with four layers of woven basalt fibers, inserted between two Al plates. Different samples are prepared, tested and studied; one group without opening and the other two groups with circular openings of radii 10 and 20 mm. In all samples buckling i...

Copyright © Korean Carbon Society http://carbonlett.org Abstract The use of carbon nanotubes (CNTs) as a reinforcing material in a polymer matrix has increased in various industries. In this study, the flexural behavior of CNT-modified epoxy/ basalt (CNT/epoxy/basalt) composites is investigated. The effects of CNT modification with silane on the flexural properties of CNT/epoxy/basalt composite...
