Cemento Maestro: reducing the clinker-to-cement ratio

Reducing the clinker-to-cement ratio . Reducing the clinker-to-cement ratio is key to cutting the carbon impact of cement. Our ambition is to reach an average clinker factor of 68% globally by 2030, by repurposing byproducts from other industries and construction and demolition waste, investing in calcined clay facilities as well as developing novel cements with new binders.
