Many reinforced concrete structures have been built in Switzerland and Central Europe since the 1960s. Time leaves its mark: chemical changes in the concrete may result in steel corrosion. Researchers ...

Reduced Steel-Concrete Bond — When steel corrodes, the corrosion products expand, leaving a compromised steel layer over the reinforcement's surface and a poor bond with the surrounding concrete.

This corrosion reduces the cross-sectional area and bond strength of the steel, resulting in cracking, spalling, and loss of strength and stiffness in the concrete elements. Moreover, corrosion ...

A newly developed machine learning model makes reliable strength predictions in carbon fiber-reinforced steel columns, ...
