Professor Tagnit-Hamou has internationally recognized expertise in the field of microstructure, the physicochemistry of silicates (cement and concrete), the development of eco-friendly concretes, and the valorization of industrial by-products. In particular, he has applied his expertise to the study of silicate reactivity for the development of blended cements such as quaternary cement based on Portland cement and supplementary cementitious materials. His expertise, at the interface of concrete technology and the physicochemistry of silicates, has enabled him to develop new cementitious materials derived from industrial by-products. This includes the successful use of glass frit in concrete (with characteristics similar to glass), which is produced industrially through the high-temperature treatment of by-products from aluminum smelters (spent potlining).

He is a Fellow and member of international technical committees of the American Concrete Institute (ACI) and the International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM). In addition to the ADRIQ tribute award (Celebrating Partnership 2011) obtained with SAQ and Tricentris, his partnerships have also been recognized with the ADRIQ “Coup de Cœur” Award (2012, Centre for Research on Insular and Maritime Environments, for integrated residual materials management) and the ADRIQ Innovation Award (2013, Kruger, biomass ash valorization). He was also the recipient of the prestigious Jean-Claude Roumain Innovation in Concrete Award from the American Concrete Institute – Strategic Development Council (2011).

 

A. Tagnit-Hamou is a member of the Research Center on Concrete Infrastructure at UdeS (CRIB-US), which has been recognized by the Fonds de recherche du Québec – Nature and Technologies (FRQNT) since 1992.

​

A. Tagnit-Hamou is the author and co-author of numerous publications in international journals such as ACI Materials Journal and Cement and Concrete Research, as well as international conferences such as the International Congress on the Chemistry of Cement and the ACI/CANMET Conference. He has also authored and co-authored several technical reports. He organized the ACI/RILEM International Conference on Cementitious Materials and Alternative Binders for Sustainable Concrete (ICCM) and two other international conferences on concrete and sustainable development (Montreal 2001 and Algiers 2002). He is an active member of several scientific associations and technical committees, including the American Concrete Institute (ACI: BAC-SD, Board Advisory Committee on Sustainable Development; Committees 130, Sustainability of Concrete, and 555, Concrete with Recycled Materials), the American Society for Testing and Materials (ASTM: technical committees C01, Cement, and C09, Concrete & Concrete Aggregates), RILEM (technical committees 224-AAM, Alkali Activated Materials, and 197-NCM, Nanotechnology in Construction Materials), and the Canadian Standards Association (CSA), where he chairs the subcommittee on the use of alternative supplementary cementitious materials in concrete (A3004-E1) as well as the subcommittee on glass pozzolans, which developed a new standard that has been in force since December 2008.
