    Production of low-energy cements would result in energy saving and lower CO2 emissions related to reduced consumption of fuel and high-grade limestone as a raw material. Belite rich clinker made more reactive by doping with combination of S and Li could possibly be one of the low-energy alternatives for Portland cement clinker. Paper describes the preparation of doped belite and deals with
