Like clinker production, clay calcination requires heat. But there is a huge different in scale: in the cement kiln temperatures reach over 1500°C, whereas clay is calcined at 650-850°C. Calcined clay production thus consumes less than half of the specific thermal energy of clinker production.

Limestone calcined clay cement (LC 3) is a promising material for producing cement with low CO 2 emissions and properties similar to, or superior to, those of Portland cement (PC), but at 50 % clinker content (LC 3-50).In many applications, lower strengths than PC are acceptable, opening new opportunities to develop suitable LC 3 …

Calcined clay and limestone, which are relatively minimally processed minerals, have lower embodied energy than OPC. The 50 % OPC clinker, 30 % calcined clay, 15 % limestone, and 5 % gypsum by mass are in conjunction to make a typical LC 3 binder [13]. The substitution of clinker can be up to 50 % without reducing mechanical …
