While cements containing 10 to 15% interground limestone are relatively new to the U.S. market, they offer an excellent opportunity to reduce the environmental footprint of concrete. Officials in Colorado and Utah have taken the initiative to be leaders in sustainable construction by allowing the use of portland-limestone cements in transportation projects. Projects presented in the article demonstrate that paving concrete made with portland-limestone cement can achieve specified strength and durability requirements.

The Slag Cement Association (SCA) presented the Slag Cement 2016 Project of the Year Awards during the meeting of ACI Committee 233, Ground Slag in Concrete, at The ACI Concrete Convention and Exposition – Spring 2017 in Detroit, MI.
