Rock Tech Lithium’s by-products boost cement strength and sustainability

Rock Tech Lithium Inc. announced a study by the German Lithium Institute confirming that by-products from its lithium conversion process can serve as precursor material in the cement industry. The study shows that leached spodumene concentrate (LSC), generated during lithium production, holds substantial industrial potential.

Composed primarily of aluminosilicates, LSC can replace fly ash, a by-product of coal-fired power generation, as a cement additive. The addition of 20% LSC to Portland cement increases its compressive strength by 10%.  The study, conducted at Martin Luther University Halle-Wittenberg, indicates that LSC can ensure the regional supply security of the German cement industry and help reduce CO2 emissions.

Rock Tech plans to build Europe’s first lithium converter in Guben, Brandenburg, aiming for zero-waste production and sustainability.
