Geofortis Pozzolans’ products use a natural pozzolan formed by volcanic ash deposited over thousands of years in a fresh water lake populated by diatomaceous algae in northern California. This unusual mineral has the potential to solve many of the technical challenges facing the concrete industry today, including ASR, efflorescence, porosity, and reducing greenhouse gas emissions.
From ancient Roman pozzolan concrete structures that have stood for millennia to modern concrete structures and products, natural pozzolans have a demonstrated ability to produce high performance and durable concrete. Innovations in product development and changing market forces now allow Geofortis to bring back a superior and proven natural pozzolan to meet the demand for high performance and cost-effective concrete solutions.
Geofortis Pozzolans sells, ships and provides services for our natural pozzolans to customers in the western US by rail or truck. Our natural pozzolan was successfully used from the 1950’s – 80’s in projects such as the Auburn Dam, Los Melones Dam, Palos Verdes nuclear power plant, and the Trans-Canada Highway. In the past, this mineral was calcined and processed in ball mills, but Geofortis has now developed and tested processes to deliver an un-calcined, finely milled product as a stand along mineral, or as a blend that meets today’s building and construction market needs.
Our raw, uncalcined product provides maximum benefit in CO2 impact calculations by replacing Portland cement and Class F pozzolan. The light beige color is excellent for most customer applications. Geofortis currently sells our unprocessed pozzolans for customer milling and will be selling milled pozzolans in late 2016.
