A recent study by the German Lithium Institute shows that by-products from lithium production, particularly leached spodumene concentrate (LSC) [aka DBS], can be used in cement manufacturing. LSC, rich in aluminosilicates, is claimed in the study to enhance the strength of Portland cement by 10% when used as a 20% additive.

Studies funded by the Australasian Pozzolan Association, haven’t show more conservative strength gains, but this was using un-beneficiated DBS.  These international developments could help supplement other current SCM’s and reduce the cement industry's carbon footprint, and hold substantial industrial potential.

“The use of industrial residues from lithium production in cements and concretes significantly contributes to the conservation of valuable natural resources,” stated Thomas Neumann, head of research and development at Schwenk Zement, another of ITEL’s shareholding companies.

“Through innovative material use, we make an important contribution to achieving our sustainability goals. By integrating these residues, we can not only reduce environmental impact but also decrease CO2 emissions.”
