DS 3 and DS 4 use either LC 3 partially in combination with NAC (i.e., consisting of LC 3 and OPC).

How much clay is used to make cement? Clay is a compact, impermeable sedimentary rock that becomes plastic, malleable, and more or less thixotropic if there is water present. Its physico-chemical properties vary in accordance with its fineness of grain. Consisting basically of aluminosilicate, it is one of the raw materials from which cement ...

notable developments in recent years is the use of calcined clays in a cement system combined with limestone [17–20], referred to as limestone calcined clay cement (LC3)[21, 22]. Calcined clays can also be used as precursors for alkali-activated cements and/or geopolymers [23–28] and in the production of lime-pozzolan cements [29],

Calcined clay limestone cement (LC 3), which is a promising new type of cement with lower CO 2 emission, is a ternary binder system made of Portland cement clinker, limestone, and calcined clay.
