Bond of Reinforcement with Normal-weight Fiber Reinforced Concrete
In reinforced concrete members, upon loading, tensile stresses from reinforcement to concrete transfer via bond. Proper bond between the two material guarantees safety of such members. This paper presents test results performed on Pull-out specimens for evaluation and comparison of bond strength behavior of Normal-weight Fiber Reinforced Concrete (NWFC)

An Experimental Study on Effect of Concrete Type on Bond Strength of GFRP Bars [PDF]
One of the common methods to create bond strength in reinforced concrete is providing development length. The bond strength of glass fiber reinforced polymer (GFRP) bar is inherently poor due to its shape, as well as its inadequate mechanical ...
