Influence of weather on the corrosion of steel reinforcement in Hong Kong

Abstract

Discusses the problem of steel corrosion in reinforced concrete experienced in buildings in Hong Kong. Outlines the range of defects, including different forms of spalling, loss of cover, major cracking and loss of cross‐sectional area of reinforcement. Explains the mechanism of corrosion of steel in concrete, detailing chloride attack, electrochemical reaction and oxygen infiltration. Discusses the effect of the Hong Kong climate on corrosion, blaming humidity levels and temperature. Suggests the installation of temperature and humidity sensors at selected locations in multi‐storey buildings.
