Limestone calcined clay cement (LC3) is a blend of two materials that, when combined, have a synergetic effect. It allows the reduction of as much as half of the clinker content, resulting in cutting up to 40% of the CO2 emissions from the cement and concrete industry. The potential for the CO2 reduction depends on the conditions of calcination and the proximity of the clay.
