Experimental Determination of Bond Stress of GFRP Bars and Concrete

Popis výsledku v původním jazyce

The objective of this paper is experimental determination and comparison of bond strength between different types of GFRP (glass fiber reinforced polymers) bars and concrete. The bond strength is affected by shape and roughness of the reinforcement bar surface and is very important for the right function of reinforced concrete. The experiment for determination of bond strength is called pullout test. During the test a GFRP bar is pulled out of the concrete cube and the displacement of the bar end is measured. Shear stress develops between the concrete and the bar. Based on the value of shear stress the results are compared. This paper clearly shows that sand coated GFRP bar has the best bond strength, which is even better than for steel. Tests were executed from November 13th 2006 to April 3rd 2007 in Experimental Center of Czech Technical University in Prague, Faculty of Civil Engineering.
