US: Eco Material Technologies has supplied its PozzoCEM Vite clinker-free cement to 3D printing construction firm Hive 3D for its The Casitas @ The Halles project in Texas. PozzoCEM Vite cement has 92% lower CO2 emissions than ordinary Portland cement (OPC). The producer said that concrete produced using PozzoCEM Vite is also more durable and longer lasting than OPC-based concrete. Eco Material Technologies and Hive 3D developed a custom batching system to mix PozzoCEM Vite cement and local Texan sand for use in the project. Eco Material Technologies said that the system created a significant cost reduction compared with other available printable mortar technologies.
Eco Material Technologies recently launched a new 99% reduced CO2 PozzoCEM formulation, which it expects to use in future projects with Hive 3D. Other reduced-CO2 cements produced by Eco Material Technologies include its PozzoSlag 50% ground granulated blast furnace slag cement. In total, Eco Material Technologies has supplied 1Mt of reduced-CO2 cements across 4000 construction sites since 2012. It said that it expects to announce multiple new infrastructure projects and strategic partnerships later in 2023.
Eco Material Technologies' CEO Grant Quasha said “Hive 3D’s commitment to building the first 100% cement replacement 3D printed homes aligns with our goal of transitioning the construction industry away from using materials that generate approximately 8% of the world’s carbon emissions each year."
