Bond of Frp Laminates to Concrete
Fiber reinforced polymer (FRP) laminates are being successfully used for strengthening of existing reinforced concrete structures. Bond of the FRP reinforcement to the concrete substrate is of critical importance for the effectiveness of the technique. In this project, flexural test specimens were prepared to address some of the factors expected to affect bond, namely, bonded length, concrete s...
متن کاملExperimental Investigation of the Methods of Evaluating the Bond Strength Between Concrete Substrate and Repair Materials
This investigation was aimed at studying the effect of test methods on bond strength between concrete substrate and repair material. Four test methods with cementations or modified-cementations repair materials, and two surface roughnesses were studied. The methods used were pull-off, slant shear, splitting prism and a new direct shear named Bi-Surface shear test. While the coefficient of varia...
متن کاملEffect of Varied Surface Roughness, Putty Thickness and Concrete Strength on the Interfacial Bond Strength of FRP to Concrete
The use of bonded fiber reinforced polymer (FRP) sheets for upgrade or repair of aging and deteriorating concrete structure has emerged as a viable and cost effective method. Previous research has identified several items that influence FRP-concrete bond strength including concrete strength, type of FRP laminate, the number of layers of the FRP laminate, and the bonding agent or epoxy saturant ...
متن کاملEffect of the Concrete Strength on the Concrete-Steel Bond in Concrete Filled Steel Tubes
In this study, the concrete-steel bond strength of concrete filled cylindrical steel tubes has been experimentally investigated. 22 short, high strength and normal concrete filled circular steel tubes were tested. Push-out test was carried out as the common method to evaluate the bond carrying capacity. Four different concrete mixes were used in preparing the specimens. The steel tubes were w...
متن کاملBond of Reinforcement in High-Strength Concrete
This paper describes an examination of the development of tension lap splices in high-strength concrete and the applicability of the restriction in the ACI 318 code where the values of √fc′ used to calculate development length shall not exceed 100 psi. The focus is on the development of splices with Grade 60 epoxy-coated and uncoated bars in normalweight concrete. A summary of the behavior of b...
