Purebase Corporation receives favorable results on its metakaolin from Penn State University and Purdue University
IONE, CA, June 14, 2023 – Purebase Corporation (OTCPK: PUBC), (“Purebase”) a diversified mineral resource company, headquartered in Ione, California.
In recent studies conducted and released by Dr. Farshad Rajabipour at Pennsylvania State University and Dr. Jan Olek at Purdue University, Purebase’s metakaolin tested very well against other pozzolans and calcined clays from across the country. The study focused on the performance of these materials in Portland cement systems. Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.
In compressive strengths, the Purebase metakaolin, along with other calcined clays, showed the highest early-age values. In total heat values, the Purebase metakaolin was near the very top, and tested above all the other natural pozzolans. In the replacement of consumed carbon-hydrogen at 28 days, the Purebase metakaolin came out on top. In average compressive strength of mortar cubes at 7- and 28-day breaks, the Purebase metakaolin was also near the very top of all competing pozzolans.
These results suggest that cement that uses metakaolin in their cement design is stronger and more durable. This helps make greener concrete which reduces carbon emissions. This confirms that Purebase is on track to help California achieve its goals as mandated by California SB596.
California SB596, a Senate Bill passed in 2021, requires the California Air Resources Board (CARB) by July 1, 2023, to develop a comprehensive plan to reduce greenhouse gas emission from the cement sector.
