Researchers turn Lithium Production Waste into Valuable Cement Additive

A peer-reviewed study published by the German Lithium Institute has unveiled a game-changing discovery for the cement industry and sustainable construction. The research, conducted at Martin Luther University Halle-Wittenberg, demonstrates that by-products from Rock Tech Lithium Inc.’s lithium conversion process can serve as a valuable precursor material in cement production. Leached Spodumene Concentrate: A Sustainable Alternative to Fly Ash The study confirms that leached spodumene concentrate (LSC), generated during the production of lithium from spodumene, holds substantial industrial potential. Primarily composed of aluminosilicates, LSC can effectively replace fly ash as an additive in cement production. This discovery comes at a crucial time, as fly ash, a by-product of coal-fired power generation, is becoming increasingly scarce. One of the most significant findings of the research is the positive impact of LSC on cement strength. When 20 percent LSC is added to Portland cement, the most widely used cement type globally, compressive strength increases by ten percent. This improvement occurs regardless of the spodumene’s origin, validating Rock Tech’s production process and procurement strategy. Ensuring Supply Security and Advancing Sustainability Goals The utilization of LSC in cement production addresses two critical industry challenges: supply security and environmental sustainability. As traditional material streams for […]
