Abstract

"The objective of this research was to investigate the bond behavior of steel reinforced polymer (SRP) and steel reinforced grout (SRG) applied as external reinforcement to concrete substrate. SRP and SRG are innovative systems developed as complimentary materials to fiber reinforced polymer (FRP). In order to develop a composite action and exploit performance of the system, bond between the reinforcement and the concrete substrate has to satisfactory. Two types of destructive tests were used to study the bond performance: pull-off and direct shear. Prior to the application of the reinforcement, the concrete substrate was roughened using waterjetting as the abrading technique. Characterization of the roughened surface was conducted using a laser profilometer that assures objective recording of the data. Different number an density of reinforcement plies, as well as surface roughness and concrete strength were the variables in the pull-off testing. Direct shear testing specimens were prepared using manufacturer's recommendations for the density of reinforcement plies, varying the bonded length and the roughness of the concrete substrate. Test results showed that bond performance of SRP is satisfactory, with the failure mode in the concrete substrate. Conversely, SRG showed failure within the layer of grout both in pull-off and in direct shear tests. Pull-off strength of SRP as well as direct shear strength appears not to be influenced by surface roughness. For SRP, direct shear test has proved the existence of the effective bond length after which the load can no longer increase"--Abstract, leaf iii.
