In view of the challenges of decarbonisation of the cement industry, the use of low-clinker ternary cements especially with calcined clays is becoming increasingly important. The combination of Portland cement clinker (K), ground granulated blast furnace slag (S) and calcined clay (Q) in ternary cements is very promising in terms of cement and concrete properties.
In this study the CO2 footprint of such cements as well as the energy required for their production was determined over a wide range of cement compositions systematically for the first time. The results were related to the strength development of the cements and the mineralogical com-position as well as the moisture of the used clays. Compared to an OPC (CEM I 42.5), both the CO2 and energy saving potentials for the production of ternary KSQ cements are between 25 and 55 % respectively, depending on the cement composition.
