Abstract
"The use of fiber reinforced polymers (FRP) is becoming more and more popular for strengthening and rehabilitating concrete structures. The high tensile and shear strength of FRP laminates is affected by the bond between the FRP laminate and the concrete surface. The effectiveness of FRP sheets in strengthening beams and columns is directly related to the degree of adhesion of the epoxy to the concrete surface. The roughness of the concrete surface is thought to be one of the principal factors that directly affect the bond strength between the concrete and FRP.
Surface characterization of concrete surfaces requires that a surface or surface profile can be measured and characterized in terms of its roughness. The focus is on the characterization of the concrete surfaces so as to produce a roughness index. This roughness index can be used to characterize a concrete surface that can be used to determine what surface texture is optimal for fiber reinforced polymer application.
A new method called “Laser Profilometry” is proposed to determine the roughness parameters. A computer program has been developed in Microsoft Visual C++ (trade name of Microsoft, Inc.) to measure the roughness of prepared concrete surfaces prior to the application of fiber reinforced polymer sheets by evaluating different roughness parameters. The most sensitive roughness parameter(s) for characterizing the surfaces was then evaluated for a variety of smooth and rough concrete surfaces"--Abstract, page iii.
