The Slag Cement Association (SCA) has been honoring the exceptional use of slag cement in concrete construction since 2010 with the Slag Cement Project of the Year Awards. Each spring the SCA holds an awards ceremony to honor the winners.

In 2021, the Slag Cement Association re-branded the program to the Slag Cement in Sustainable Concrete Awards Program.  The categories awarded include; Architectural, Durability, Infrastructure, High Performance, Innovative Applications, and Lower Carbon Concrete. 

In 2023, the research project award was renamed to the Michael Thomas Research Award to honor his legacy of advancing the research on supplementary cementitious materials (SCMs) and for being an exceptional advocate of slag cement. Research winners receive a $1,000 stipend from the SCA to help attend the ceremony, usually held in-person.

The 2024 Awards Ceremony will be held in conjunction with the Spring ACI Concrete Convention Toronto, Ontario, Canada on Wednesday, April 2nd, 2025. More information on the award ceremony will be available soon.
