Abstract: In this paper it is explained why the best way to lower the environmental impact of cementitious materials is to increase the level of clinker substitution in blended cements. The conventional clinker substitutes: slag and fly ash are in relatively short supply compared to the amount of cement used worldwide. Calcined clay present the best option to increase the supply of supplementary cementitious materials. These are most interesting when substituted in combination with limestone to give LC3: limestone calcined clay cement. To understand the durability of blended cement we need to develop a generic approach based on understanding the phase assemblage and pore structure of these materials. This approach is illustrated by the example of chloride ingress in LC3, which also highlights some of the outstanding questions which need to be solved.
