PCA’s just-launched microsite, www.greenercement.com, supports the use of portland-limestone cement (PLC), which performs in concrete at levels comparable to Type I portland cement, but exhibits a greenhouse gas emissions profile up to 10 percent below clinker-only powder. The site accesses a calculator where design and construction professionals can input building size or pavement length to see how much PLC can reduce a project’s overall carbon footprint. In addition, greenercement.com features case studies, applications, frequently asked questions, plus the status of PLC acceptance among concrete practitioners in the United States and around the world.
“PLC is another example of the cement industry evolving, continuing to innovate and sustainably producing the high-quality cement needed to help keep America’s infrastructure strong and resilient,” says PCA CEO Mike Ireland. “This initiative will help educate engineers and other specifiers on how PLC can easily be incorporated into numerous projects.”
