Abstract. The use of technogenic raw materials as input products in the production of portland cement provides for considerable reduction of energy consumption during clinker burning. The study reveals the mineral formation features caused by the change of the liquid phase composition and crystallization of silicate phases.
Specifically, cement producers would optimally reduce their emissions by 78% at a carbon price of €100 per ton of CO2, while €155 per ton would provide incentives sufficient for near-full decarbonization. Our findings are generally more favorable than those reported in earlier studies regarding the cost of decarbonizing cement production.
