Corrosion of Steel in Concrete

The premature deterioration of concrete structures due to corrosion of the steel reinforcement is a major problem in the field of civil engineering, particularly when aggressive environmental conditions are encountered. This paper presents an acute case of widespread corrosion damage observed on a ground slab of a huge prestigious building complex constructed at the southern part of Iraq in the late eighties. The paper describes the remedial measures necessary for extending the service life of the structure. The test programme comprises detailed visual inspection of the retrieved samples including the condition and the number of protective layers, thickness of cover to reinforcement, description of reinforcement size and distribution, signs and degree of corrotion. The concrete cores were then subjected to different chemical and physical tests.

Parking Structures pp Cite as. Although concrete is a relatively durable construction material, preventive maintenance and necessary corrective actions are required to extend the useful life of parking structures. Parking facilities experience harsh exposure conditions which can contribute to accelerated concrete deterioration and adversely affect the life expectancy of the structure. Quite often, owners and operators have to repair deteriorated structures with only years of service Figure 15—1. Unable to display preview. Download preview PDF.

Furthermore, for those assessingthe condition of structures in the eld, it appears that one mainobjective is to make as many measurements as possible in as short atime as possible, in order to reduce costs. This push for speed is, again,the cause of some of the problems described below. Other problemareas are the use choice of appropriate electrochemical techniquesand specimen details. One problem, which cannot readily be over-.
