Natural Pozzolans

As the cement and concrete industries work to reduce carbon emissions and strengthen supply chains, natural pozzolans have re-emerged as a critical solution. These naturally occurring siliceous and aluminous materials react with lime in cement to improve strength, durability, and long-term performance—while significantly lowering the carbon footprint of concrete production.

At Western Cobalt, we are identifying and advancing high-quality pozzolan deposits across the western United States to help meet the growing demand for low-carbon alternatives to traditional Portland cement. Our goal is to partner with cement producers and construction material companies to secure domestic, sustainable sources of pozzolans that enhance performance and resilience in modern infrastructure.
