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 available polymer, Pluronic P123. Pluronic is able...

Practical Corrosion Control Measures for Elemental Sulfur Containing Environments

This paper provides an overview of materials’ performance in well environments containing H2S and elemental sulphur (S). Based on this information the factors affecting the service life of materials used for well completion and surface facilities in highly sour environments are discussed and limitations on materials selection and chemical inhibition procedures are suggested.

Corrosion-Induced Concrete Cracking Model Considering Corrosion-Filled Paste

A TCP–TCL model is established to describe the relationship between the thickness of the corrosion-filled paste (CP) and that of the corrosion layer (CL). This model can describe the phenomenon that the corrosion filling in the concrete pores and accumulating at the steel/concrete interface occur synchronously. Based on the TCP–TCL model, a corrosion-induced concrete cracking model, which can q...

Multilayer Nano Films for Corrosion Control

Nano films consisting of an alternating sequence of positively and negatively charged polyelectrolytes have been prepared by means of the electrostatic layer-by-layer (LBL) sequential assembly technique on treated and untreated mild steel wires. Inhibitor was encapsulated between cationic and anionic polyelectrolyte nano films. This paper mainly focuses on the effect of these nano-films of poly...
