Erformance of structures in a corrosive environment

Abstract EN

This paper describes a review on the major factors affecting reinforcement corrosion in concrete structures in the Arabian Gulf region and case studies on the performance of concrete structures in Madinat Al-Jubail Al Sinaiyah.

The effect of high salinity and concomitant presence of chlorides and sulfates in ground water and soil and high ambient temperature on reinforcement corrosion are presented.

Examples on the performance of concrete structures in Madinat Al-Jubail Al Sinaiyah, which has exposure conditions typical to those in the Gulf region, are presented.

Emphasis is given on the structures that are generally susceptible to reinforcement corrosion.

Available data on the performance of some of the concrete protection measures, such as use of mineral admixtures, increased cover over reinforcing steel, surface coatings and use of waterproofing membrane are also reported.
