Calcined clay limestone cements (LC3)

Studies at EPFL [10], [11] have shown that a kaolinite content of only about 40% in a mixture of LC 3-50 (50% ground clinker, 30% calcined clay, 15% limestone, 5% gypsum) is sufficient to give mechanical properties comparable to the reference plain Portland cement from about 7 days (EN 196-1 mortar bars w/c = 0.5, sand/cement = 3 …

Pilot Scale Production of Limestone Calcined Clay Cement

Limestone Calcined Clay Pozzolan, or LC 2, was produced by intergrinding 66% calcined clay and 34% limestone. After the grinding it was found that most of the powder passed through the 45 µm sieve. The Blaine's fineness of the LC 2 produced was more than 1000 m 2 /g and was difficult to measure accurately. Due to the similar …

Clay Calcination

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. Even more importantly – and unlike limestone – calcining clay does not release CO2.
