A Microscopic Look at Timber–Concrete Bonding
Under the microscope, the interface between timber and concrete reveals remarkable detail. When the two materials are bonded with resin, the resin penetrates deep into the wood structure, creating a complex mechanical interlock. At the same time, the concrete surface, shaped by its formwork and influenced by the release agent, shows different textures that affect how the bond develops.
These microscopic characteristics play a decisive role in determining bond strength. Each fibre, pore, and surface irregularity contributes to the performance of adhesively bonded timber–concrete composite (TCC) systems.
This is where the real “magic” of the construction method happens: at the interface, where materials meet, interact, and ultimately form a composite with unique structural potential.
