Utilization of Iron Ore Tailings as Raw Material for

Mar 16 2016 The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings IOT to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose two kinds of clinkers were prepared one was prepared by

The role of limestone and calcined clay on the rheological

Mar 01 2020 Clay containing kaolinite is abundantly available in the earths crust and when calcined and used together with limestone it yields comparable physiochemical properties and better durability when compared with pure ordinary Portland cement OPC even at 50 clinker substitution . This renders limestone calcined clay cement LC3 a viable alternative for the future of green cement.

Calcined clay limestone cements LC3 ScienceDirect

The major innovation presented here is the possibility to make a coupled substitution of cement with calcined clay and limestone. This allows much higher levels of substitution. Blends where calcined clay is used as a pozzolan typically have clinker contents around 6570. Combination of calcined clay with limestone allows higher levels of substitution down to clinker contents of around 50 with similar
