Investigation on use of basalt fiber reinforced polymer for improvement in flexural strength of reinforcement concrete

Basalt fiber is a green, healthy and environmentally friendly high-tech fiber product without environmental pollution. It is widely used in military and civilian fields. It is not only of great theoretical significance but also of great strategic significance to strengthen the damage structures and members. The results show that, compared to glass fiber, carbon fiber and aramid fiber, basalt fiber, has good mechanical properties, acid-alkali resistance, excellent electrical properties, high wave permeability, non-conductive, and excellent sound insulation and insulation performance. This experimental study was conducted to determine the feasibility of using externally bonded BFRP fabrics to strengthen RC beams. Nine full-size specimens were tested. The following conclusions have been drawn from this research that of 4 types of different wrapping to the beam, beam with fully wrapped BFRP gained more flexural strength and load carrying capacity as compared to control beam.
