Time leaves its mark: chemical changes in the concrete may result in steel corrosion. Researchers at ETH Zurich have now developed an innovative method for precisley locating corrosion, even in ...

Steel can stretch, adding steel bars gives the concrete some tensile strength to go along with ... This does three things: it protects against corrosion, it locks in the tendon before tensioning ...

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 ...

As part of addressing this problem, a team at TU Dresden in Germany have completed what is believed to be the world’s first building made with carbon-reinforced concrete, in which the steel ...
