    ABOUT

    Dr. Sanchez is an Associate Professor at the University of Ottawa. His expertise is related to the development of sustainable concrete materials and concrete durability, especially the diagnosis and prognosis of concrete affected by Internal Swelling Reactions (ISR). He has co-authored over 100 refereed publications on these topics and contributed to the development of standard test protocols, along with descriptive, empirical and numerical models for the design and assessment of concrete. Dr. Sanchez is an active participant on several national and international committees related to concrete sustainability and durability and is currently the deputy chair of the RILEM TC AAR - Alkali-aggregate mitigation in concrete. Dr. Sanchez is a reviewer for a number of important journals in the field and is a recipient of highly prestigious awards such as VANIER PhD scholarship (2010), NSERC Early Career Research Award (2016), NFRF-Exploration grant (2019), and the distinguished Ministry of Ontario Early Research Award (ERA) in 2021.

    Worked with advanced concrete mix-design methods to efficiently proportion mixtures towards a greener future of the concrete industry, using alternative and sustainable materials. He also developed and published a new testing setup for direct shear in cylinders to quantify alkali-silica reaction (ASR)-induced expansion and damage in concrete, which has a significant scientific and practical impact on assessing the damage of concrete infrastructures affected by ASR.
