Use of Slags in the Production of Portland Cement Clinker [PDF]
, 2019 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.
