The use of supplementary cementitious materials (SCMs) to replace part of the clinker in cement is the most successful strategy to reduce CO₂emissions in the global cement industry. Combination of calcined clay with limestone allows higher levels of substitution down to clinker contents of around 50% with similar mechanical properties and improvement in some aspects of durability.  The main objective of the paper is to focus on production, techno-economic feasibility, environmental impact and cost effectiveness of the LC³ cement. LC³ may be a new sort of cement supported a mix of limestone and clacined clay.
