Modelling the electrical resistivity of concrete with varied water and chloride contents (2019)
Journal Article

The electrical resistivity of concrete is an important property in the assessment of reinforcement corrosion in concrete and an essential parameter in the design and operation of cathodic protection for reinforced-concrete (RC) structures. Water and... Read More about Modelling the electrical resistivity of concrete with varied water and chloride contents.

An experimental study of cathodic protection for chloride contaminated reinforced concrete (2018)
Journal Article

Cathodic protection (CP) is being increasingly used on reinforced concrete structures to protect steel reinforcing bars from corrosion in aggressive conditions. Due to the complexity of environmental conditions, the design specifications in national...

An experimental study of concrete resistivity and the effects of electrode configuration and current frequency on measurement (2018)
Presentation / Conference
Oleiwi, H., Wang, Y., Xiang, N., Augusthus Nelson, L., Chen, X., & Shabalin, I. (2018, July). An experimental study of concrete resistivity and the effects of electrode configuration and current frequency on measurement. Presented at Sixth International Conference on Durability of Concrete Structures, University of Leeds, UK

Electrical resistivity, a measurable parameter of the state of concrete, plays an important role in the assessment of reinforced concrete structures. An experimental study using two-electrode method has been conducted to evaluate the resistivity of P...

Use of finite element analysis to investigate the structural behaviour of masonry arch bridges subject to foundation settlement (2018)
Presentation / Conference Contribution

This paper investigates the effect of foundation settling on masonry arch bridge structural behaviour using Finite Element Analysis (FEA). Masonry arch bridges form a
large proportion of existing European infrastructure such as rail and road bridges... Read More about Use of finite element analysis to investigate the structural behaviour of masonry arch bridges subject to foundation settlement.

Experimental & numerical simulation of soil boundary conditions under dynamic effects (2018)
Presentation / Conference
Qaftan, O., Weekes, L., Toma-Sabbagh, T., & Augusthus Nelson, L. (2018, June). Experimental & numerical simulation of soil boundary conditions under dynamic effects. Presented at 16th European Conference on Earthquake Engineering (16ECEE), Thessaloniki, Greece

When conducting earthquake simulation tests, one of the main concerns is the modelling of boundary effects created by artificial boundaries of a soil model container. The function of this soil container is to hold the soil in place during the excitat... Read More about Experimental & numerical simulation of soil boundary conditions under dynamic effects.

Influence of railway loading on the performance of soil-filled masonry arch bridges (2018)
Journal Article

Masonry arch bridges are found in large numbers on the rail networks of Europe and other parts of the world. However, the mode of response of masonry arch structures subjected to railway loading is little understood. To address this, an experimental...

Long term durability properties of concrete modified with metakaolin and polymer admixture (2018)
Journal Article
Al Menhosh, A., Wang, Y., Wang, Y., & Augusthus Nelson, L. (2018). Long term durability properties of concrete modified with metakaolin and polymer admixture. Construction and Building Materials, 172, 41-51. https://doi.org/10.1016/j.conbuildmat.2018.03.215

Previous studies show that both metakaolin (MK) and polymer can respectively improve certain mechanical and durability properties of concrete. Also, recent studies show that a combination of MK and polymer further enhances the mechanical properties b...
