Factors influencing chloride transport and chloride threshold level for the prediction of service life of concrete structures
In this study, the influence of parametric values on the risk of steel corrosion in concrete was quantitatively calculated in terms of the sensitivity to service life of concrete structures subjected chloride attack. Prior to the analysis, a thorough literature review on the chloride threshold level (CTL) for steel corrosion and the rate of chloride transport was performed to define the ...

Biocorrosion in drinking water pipes
Copper is widely used in drinking water distribution systems due to its relatively low cost and favorable mechanical properties. However, copper corrosion may generate copper concentrations exceeding the thresholds prescribed by international drinking water standards. In-situ measurements performed in an actual system found that the copper mass released under flowing water conditions (pipe ...

Gas Evolution from Battery Electrodes
Although tremendous efforts are made in developing stable Zn electrodes and bifunctional catalysts in rechargeable Zn–air batteries, the charging process is seldom reported. Herein, an in-depth investigation into the gas evolution on the air electrode is conducted by in-situ characterization. It is found that the charging process can be divided into three stages: no obvious bubbles, small ...

Non-destructive analysis of concrete for corrosion studies using nuclear technique
Chloride-induced reinforcement corrosion is the principal cause of deterioration of concrete structures in the Arabian Gulf and the world over. Preventive measures against corrosion require maintaining the chloride and sulphate concentration in concrete below the threshold limits specified by the standards. This requires monitoring the chloride and sulphate concentration in concrete, and a ...

Application of data mining techniques in building predictive models for oil and gas problems: a case study on casing corrosion prediction
This paper describes the use of (supervised) data mining to predict casing corrosion in carbon geological storage projects. This study discusses: 1) data pre–processing such as missing value handling and discretisation; 2) feature selection methods such as correlation coefficient, signal–to–noise ratio, information gain, Gini index, and the k–nearest neighbour (KNN) approach; 3) classification ...

Corrosion, the invisible enemy of WWTPs
Corrosion is the natural process in which metals degrade. This process is influenced by external factors such as humidity, temperature and corrosive gases, mainly active sulfur compounds, sulfide oxides and nitrogen oxides (H2S, SO2, SO3, NOx). In pumping stations and sewage treatment plants these factors are present, even in very low concentrations (parts per billion), and are the cause of ...
