The pull-off strength test, particularly in the context of Fiber-Reinforced Polymer (FRP) testing, is significant for evaluating the bonding strength between FRP materials and concrete substrates.

The pull-off strength test, specifically in FRP testing, measures the force required to detach an FRP material from a concrete substrate. This test assesses the adhesive bond strength between the FRP and the concrete surface. It’s particularly crucial for applications such as strengthening concrete beams, columns, or slabs using externally bonded FRP systems.

By conducting pull-off strength tests on FRP-concrete interfaces, engineers can ensure the reliability, safety, and effectiveness of FRP strengthening or reinforcement applications, contributing to the overall performance and durability of concrete structures.
