Concrete International magazine covers advancements in lowering carbon emissions as the effects of global warming rise. “Limestone Calcined Clay Cement Makes Inroads in Reducing Carbon Emissions,” written by industry leaders Andrea Schokker and Karen Scrivener, covers a process that has produced substantial results. This is the use of limestone calcined clay cement (LC3). LC3 contains about 50% ordinary portland cement (OPC), providing the same ease of use and strength as OPC, and is the most effective way to reduce the amount of clinker used. Using LC3 can save up to 40% CO2 emissions compared to OPC. Learn more.
