SCA Honors 13 Slag Cement Projects

The Slag Cement Association (SCA) announced the recipients of its 2021 Slag Cement In Sustainable Concrete Awards program. These awards were unveiled and celebrated during the American Concrete Institute Spring Convention last week.

Thirteen construction projects from across the United States were chosen to showcase the broad applications of slag cement and its impact on creating more durable and sustainable concrete. Two research projects on slag cement use were also honored in this year’s program. 

“This year’s winners include notable infrastructure and paving projects. All of these winners illustrate how slag cement works to improve the durability of concrete while lowering the embodied carbon associated with concrete production,” said SCA.
