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...

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.

Shear behaviour of lightweight concrete beams strengthened with CFRP composite (2018)
Journal Article
Al-Allaf, M., Weekes, L., & Augusthus Nelson, L. (2019). Shear behaviour of lightweight concrete beams strengthened with CFRP composite. Magazine of Concrete Research, 71(18), 949-964. https://doi.org/10.1680/jmacr.17.00488

This paper presents the experimental results obtained from lightweight and normal concrete beams with closed and U-shaped configurations of epoxy bonded Carbon FRP (CFRP) reinforcement in order to compare the shear resisting mechanisms between lightw...

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...
