Chloride-induced corrosion of steel reinforcement in alkali-activated slag/ metakaolin blended concretes

The aim of this study is to understand the corrosion mechanism of steel embedded in alkali-activated slag/metakaolin blended concretes via electrochemical testing after 407 days of exposure to a 3.5 wt.% NaCl solution, with an emphasis on characterising the material prior to the onset of corrosion. In order to accurately depict the material’s...

Polymeric nano-materials for corrosion control of steel in concrete

Polymeric nano-materials utilization in reinforced concrete, aiming to deal with steel corrosion was developed in previous works. Promising results were obtained with PEO–b–PS nano-formations, both in terms of enhanced bulk matrix properties and improved steel corrosion resistance. Recent research has been focusing on a cheaper and commercially...

Self-healing corrosion protective coatings by TiO2 particles and a pH-sensitive organic agent on a magnesium alloy

A self-healing corrosion protective coating was developed using TiO2 particles and casein as pH-sensitive organic agents that is also environmentally friendly materials. A film structured of TiO2 particles was formed on a substrate (magnesium alloy) by dip-coating followed by immersion in a casein solution. Casein was inserted and fixed in the...

Modeling stray current and its influence on corrosion of steel sheet piling

Stray currents are known to promote corrosion of nearby metallic structures. Electrolysis is the responsible phenomenon. Where currents enter the metallic structure, the latter is protected. The construction corrodes at the location where currents exit through the ground to be collected by the substation. The extent of such corrosion has until...
