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...

This cover designed by Muhammad Irfan and colleagues shows how High Performance Polyethylene (HPPE) fibers are relatively tougher than carbon can be used to improve impact tolerance of epoxy composite laminates. Composite laminates containing suffer from delamination upon impact. An interleave a tough material like HPPE inserted between these fiber plies reduce the damage due do not undergo bri...

Concrete is poor in tensile property due to its brittle nature. Improvement the mechanical properties of concrete carried by combining rebars and fibers concrete. Earlier research state that non-metallic fibres improve pre-crack performance metallic post crack performance. Short resist micro-cracks at an early stage long macro-cracks. The combination short makes much effective. In this study, i...

The corrosion of rebar is one the main problem in construction industry. A lot amount spent on repair work every year but none them that effective. Therefore, recent studies are being conducting FRP due to brittle nature and bonding performance. We have also used PVA fiber concrete increase strength concrete. we using Hybrid beams which replaced corner with BFRP bars because their superior effe...

fast fracture is one of the major failure modes in brittle polymers. generally, crack growth in these polymers may occur under combined tensile-shear loading. however, the fracture test data reported previously for some dental restorative resins can not be predicted by using the available fracture criteria.in this paper, a modified fracture criterion is used for estimating the fracture load for...
