Purebase Corporation announced its new natural pozzolan product, HP-SCM, had successfully completed ASTM C618 and AASHTO M295 compliance testing at an accredited concrete lab. This high-performance Supplementary Cementitious Material (SCM) has been developed to not only replace fly ash and slag in concrete mix designs but is also a high-end pozzolanic replacement for cement (anywhere from 20% - 40%). Compressive strengths of concretes incorporating HP-SCM can exceed the strength of typical straight cement mixes at 28 days, which is not typical of an SCM. Cement can be replaced at up to 40% with HP-SCM without sacrificing performance while significantly reducing the carbon footprint of the concrete. Cement is a notable contributor to harmful greenhouse gas emissions, so reducing the amount of cement in concrete is increasingly becoming a goal of many countries around the world, as well as many municipal jurisdictions within the U.S.Purebase is currently working with research laboratories to quantify the amount of carbon reduction of HP-SCM.
