LC3 stands for Limestone Calcined Clay Cement and was developed by the Swiss Federal Institute of Technology in Lausanne ( EPFL ). It is a sustainable cement product that has a clinker content that is up to 50 percent lower than that of traditional cement. Clinker makes a significant contribution to CO2 emissions during cement production. In LC3, a large proportion of clinker is replaced with a new additive, which means that overall less CO2 is emitted in cement production.
The Zug-based construction chemicals group Sika wants to support the market launch of LC3, as he writes in a press release. He wants to develop and offer special cement additives and concrete admixtures that help customers adapt their materials to the properties of LC3. This should enable the water consumption, workability, hardening and durability of the LC3 concrete to remain the same compared to conventional products. According to its own statements, Sika is also ready for “comprehensive product tests with interested customers”.
"With these new LC3 products, we are putting the goals of our sustainability strategy into practice," said Frank Höfflin, Sika's head of technology, in the press release. “Our aim is to act as an enabler for sustainability in the construction industry and to develop more environmentally friendly and more efficient products,” he emphasizes.
