 Course Overview

The corrosion of reinforcing steel in concrete structures such as buildings, car parks, concrete marine structures, road beds, bridge decks and bridge substructures is a world-wide problem and leads to cracking, staining, spalling from the surface and ultimately structural weakness. This 5-day advanced course thoroughly and systematically covers the concrete durability issues: the causes of reinforcement corrosion, common control and prevention methods for both old and new structures, surveying and diagnosing techniques for condition assessment, the conventional and some promising emerging technologies for repair and rehabilitation of concrete structures. Participants will gain essential knowledge and skills in managing corrosion in concrete structures. Engineers, architects and designers will grasp the theories and practices of corrosion control and prevention which would lead to corrosion-proof designs and low cost durability. Participants will also learn the principles and applications of advanced corrosion sensors and monitoring systems for life prediction, repair and rehabilitation, surveying, diagnosis and condition assessment. Facility owners will benefit from increased durability, enhanced safety and reduced maintenance costs.


This corrosion short course can be taken as in-house training course, online course and distance learning course worldwide. It can also be customized to meet the specific needs of your organization.
