For concrete bridge projects in marine environments, attention must be paid to the reinforcement corrosion problems caused by chloride intrusion. As kinds of functional admixtures, which can reduce the reinforcement corrosion rate, corrosion inhibitors are becoming very popular in China in new bridge projects. Corrosion inhibitors cover both inorganic and organic inhibitors. Nitrite is represen...

The effect of oil soluble commercial corrosion inhibitors (OSCI) on the growth of bacteria and its corrosion inhibition efficiency were investigated. Corrosion inhibition efficiency was studied by rotating cage test and the nature of biodegradation of corrosion inhibitor was also analyzed by using FTIR, NMR and GC-MS. This isolate has the capacity to degrade the aromatic and aliphatic hydrocarb...

The cooling water chemistry has changed steadily over the past decade. Use of high performance antiscalants, corrosion inhibitors, polymer for better dispersion, total prevention of microbial deposits by using powerful biocides and biodispersants, pH boosters and advanced hardness stabilizers is the current practice. But addition of so many different chemicals to the cooling water system (CWS) ...

Titanium tubes generally exhibit superior resistance against electrochemical corrosions amid seawater for their passive films TiO2. However, hydrogenassisted corrosion (HAC) is actually the Achilles’ heel to titaniummaterials when the temperature exceeds near 70 8C. In this event, severe degradations like quick thinning and leakage were frequently detected on a large number of titanium tubes ex...

Abstract: This research examines the performance of strengthened non-uniformly corroded reinforced self-consolidating concrete (SCC) members. This paper focuses on three aspects of concrete including corrosion, concrete cover loss, and repair technique. Up to a 50% corrosion level is considered in this study. Corrosion was experimentally induced and was simulated in other cases. Twenty-six rein...

Marine services and industry have emerged as one of the most significant pillars global economic growth. Corrosion materials, on other hand, is still important issue for marine structures equipment. a major contributor to degradation offshore structures. It has an effect life process equipment, might lead structural failure, leakage, product degradation, contamination, even death. investigate m...
