Germany: Canada-based company Rock Tech has promoted a peer-reviewed study by the German Lithium Institute that confirms the potential of byproducts from lithium production to be used in cement manufacture. The study found that leached spodumene concentrate (LSC), primarily composed of aluminosilicates, can replace fly ash as an additive in the cement industry. The study also revealed that adding 20% LSC to Portland cement increases its compressive strength by 10%. The process for producing and utilising LSC has been submitted for a patent.

"The phase-out of coal and the transformation of the steel industry will sooner or later lead to changed or disappearing material streams that have been significant for the cement industry in terms of CO₂ savings and product portfolio. The LSC from lithium production has the potential to compensate for these depleting material streams in the future."

Chile: Cementos Bío Bío has changed its name to Cbb as as part of a rebranding exercise to target the group for the digital age and to target growth outside of Chile. Chief executive officer (CEO) Enrique Elsaca said that the change is part of the company’s Transforma 2021 plan, including investment of US$150m in Chile, Argentina and Peru, according to the El Mercurio newspaper.

It is about to inaugurate a cement grinding plant at Arica in Chile, it plans to build a US$20m plant at Arequipa in Peru for commissionoing in early 2020 and it plans to upgrade its San Juan lime plant in Argentina. It also hopes to build a new lime plant in northern Argentina to supply the lithium business.
