Project Description

The need for upgrading Reinforced Concrete (RC) structures especially for those having high importance to society (electric power plants, hospitals, schools etc.) has increased significantly due to public safety and maintenance cost issues. The use of Textile Reinforced Mortars (TRM) to retrofit, RC elements have emerged as a promising alternative to the use of Fibre Reinforced Polymers (FRP), mainly because of TRM's improved performance at elevated or low temperatures, on wet surfaces, at aggressive environments, but most importantly their sustainability. At the same time organic corrosion inhibitors such as small-molecule-based alcohol amine series are becoming the focus of attention due to their environmental friendly behaviour. This study investigates the repairing and/or strengthening of large scale concrete columns suffering from corrosion problems with the use of different types of corrosion inhibitor incorporated patch repair mortars and TRM.

Funding Notes

The PhD studentship is available for three years subject to satisfactory progress by the student. The award covers tuition fees for three years (currently equivalent to RMB 80,000 per annum) and provides a monthly stipend of 5,000 RMB as a contribution to living expenses. It also provides up to RMB 16,500 to allow participation at international conferences during the period of the award. It is a condition of the award that holders of XJTLU PhD scholarships carry out 300-500 hours of teaching or research assistance work per year. The scholarship holder is expected to carry out the major part of his or her research at XJTLU in Suzhou, China. However, he or she is eligible for a research study visit to the University of Liverpool of up to three months, if this is required by the project.
