Ruston, LA – Professors Henry Cardenas and Sven Eklund, and Ph.D. candidate Kunal Kupwade-Patil of the College of Engineering and Science at Louisiana Tech University will present their award-winning paper at the Second International Conference on Sustainable Construction and Materials Technologies in Ancona, Italy, in June.
The abstract titled, Corrosion Mitigation in Mature Reinforced Concrete using Nanoscale Pozzolan Deposition, was one of twelve papers chosen out of 350 abstracts submitted to the conference’s organizing committee. Of those abstracts, 260 manuscripts were then considered, with the final list narrowed to twelve outstanding papers.
The technology presented in this paper uses electricity to purify concrete that is contaminated with salt and is suffering from corrosion. While the salt is being pulled out, the electricity injects nanoparticles that navigate through the concrete pores and form a barrier of protection around the steel reinforcement.
The paper describes how this technology radically enhanced the corrosion resistance of the steel reinforcement over the three year duration of the research project.
