Corrosion Product Filled Paste and Corrosion Layer in Reinforced Concrete Beam at Coastal Atmosphere
Year: 2026
Type: article
Abstract: This study investigated the corrosion product filled paste (CP) and corrosion layer (CL) of a beam from a concrete structure at coastal atmospheric environment. The structure was built in 1970s and near the east sea. Part of the beam was cut into several blocks and then polished. The thickness of CP (TCP) and CL (TCL) were observed and measured by scanning electron microscopy. A TCP–TCL model in marine atmosphere is proposed, which provides a mechanistic basis for predicting corrosion evolution and guiding maintenance strategies for aging marine concrete structures. The steel corrosion and values of kT and TCPmax, in the TCP–TCL model of the steel bars, near the windward surface, are larger than those near the leeward surface.
