Limestone calcined clay cement (LC 3) concrete design scenarios (DS 1 to DS 4) DS 1 and DS 2 utilised LC 3 in the entire structure amounting to reduction and increase in the strength of concrete by 14% and 9% respectively. DS 3 and DS 4 use either LC 3 partially in combination with NAC (i.e., consisting of LC 3 and OPC).

Calcined clay – or metakaolin – is produced by heating a source of kaolinite to between 650°C and 750°C. Kaolin is both naturally occurring, as in china clay deposits and some tropical soils, as well as in industrial by-products, such as some paper sludge waste and oil sands tailings. It is a pozzolanic material with smaller particle size ...
