Strengthening Of Concrete Elements Using Basalt Fiber. Repair And Rehabilitation Of Structures

      Аннотация: Worldwide, a great deal of research is currently being conducted concerning the use of fiber reinforced plastic wraps, laminates and sheets in the repair and strengthening of reinforced concrete members. Basalt fiber-reinforced polymer (BFRP) application is a very effective way to repair and strengthen structures that have become structurally weak over their life span. BFRP repair systems provide an economically viable alternative to traditional repair systems and materials. Experimental investigations on the cube, cylinder & Flexural RC beams strengthened using basalt fiber unidirectional cloth is carried out. Externally reinforced concrete beams with epoxy bonded cloth were tested to failure using a symmetrical one point concentrated static loading system. Seven beams weak in Flexure were casted, out of which one is controlled beam and other beams were strengthened using basalt unidirectional cloth in Flexure. The strengthening of the beam is done with different amount and configuration of BFRP cloth. Experimental data on load, deflection and failure modes of each of the beams were obtained.
