Protection against corrosion of concrete reinforcement in marine environment - case study Westport, Klang / Ahmad Zaril Muhamad Jamal

Corrosion of concrete reinforcement can threaten the integrity and safety of a concrete structure and is a wide spread problem in coastal regions. Corrosion can lead to spalling, loss of reinforcing steel, loss of structural integrity, and reduced service life. Lately, a number of accidents that involved lost of life and property due to lack of control of concrete quality in several constructions have been widely reported. These include, sudden collapse of the floor of a building during construction, the collapse of a jetty in Penang, hotel in Singapore and Thailand and condominium collapse in Ulu Klang. First of all, this dissertation discusses the goal, scope and research methodology of this study. The dissertation contains reviews in theoretically the characteristic and the behavior of reinforcement concrete. Besides that, it also focuses on why and how corrosion occurs. Discussed in this chapter are explanations of: the basics of corrosion theory, corrosion zones, and forms of corrosion, corrosion process and effects. This is followed by a comprehensive discussion on the suitable method of protection and others method available to protect from corrosion of reinforce concrete. From there on, the dissertation will analyze and determine the level of corrosion at the selected jetty/port of the case study and Investigate into several different effective and economical ways to protect reinforcing steel at the jetty from further rapid deterioration.
