Replacement of steel rebars by GFRP rebars in the concrete ...

Jun 01, 2018  Experimental researches on some of concrete structures reinforced with GFRP bars were done (5–8) years ago. The results have shown that GFRP rebars weren't subject to any degradation process in existence of the alkaline and corrosive environment .. The tensile and shear strengths of GFRP bars by using four various diameters (20, 22, 25, 28 mm) have been discussed by authors.

Ductile corrosion-free GFRP-stainless steel reinforced ...

Corrosion of steel rebars is known to cause deterioration of concrete structures that can lead to catastrophic failures.To mitigate this problem, steel rebars can be replaced with Glass Fiber-Reinforced Polymer (GFRP) rebars. However, the lack of ductility of GFRP-reinforced elements has prevented their use in many structural applications, especially in seismic areas.
