Bond Behavior between Fiber-Reinforced Polymer. Laminates and Concrete by Kasumassa Nakaba, Toshiyuki Kanakubo, Tomoki Furuta, and Hiroyuki Yoshizawa. This research examines the bond behavior between fiber-rein- forced polymer (FRP) laminates and concrete. To obtain the local bond stress versus slippage.

Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time. Most concretes used are lime-based concretes.

Spec Bond 50 is a 50% solids, two-component, high modulus, moisture tolerant structural epoxy bonding adhesive. Primary use is for bonding fresh concrete to hardened concrete and for bonding steel to fresh concrete. Spec Bond 50 has excellent adhesion to most con- struction materials. Apply by brush, roller or spray,

Good bonding between reinforcing steel and concrete is essential for the reliable performance of reinforced concrete structures. When protective coatings on steel are used, it is essential to ensure they do not reduce bond strength. Studies on the bonding of galvanized and black steel bars to.
