C-Crete Technologies, a trailblazer in developing cement-free concretes with zero CO2 emissions, proudly unveils the world’s first basalt-based concrete. This milestone marks a significant stride in the company’s mission to revolutionize the construction materials industry with eco-conscious innovations.
The recent deployment of basalt-based concrete at 7200 Woodlawn in Seattle on March 14 signifies a breakthrough in sustainable construction. This 20-ton pour, utilized for an outdoor concrete foundation, replaces Portland cement entirely with basalt as the primary binder. Notably, this pour adds to C-Crete’s growing portfolio of cement-free concretes, each utilizing distinct feedstocks like zeolite or basalt.
Basalt, abundant in silicon, aluminum, and calcium, offers a promising alternative to traditional Portland cement. Unlike the latter, which contributes significantly to global CO2 emissions, basalt is a naturally occurring, non-carbonate rock that can be ground into cement powder without the environmental concerns associated with production processes.
Furthermore, the curing process of basalt-based concrete actively captures CO2 from the atmosphere, enhancing its eco-friendly profile.
Donald Davies, owner of the Seattle building and chair of Building Transparency, praises the significance of this deployment, transitioning basalt-based concrete from a novel material to a pilot-ready solution for larger projects. With compressive strength exceeding 5000 psi and meeting ASTM International standards, this concrete variant maintains cost-parity with conventional counterparts while demonstrating comparable performance metrics.
Industry veterans like Allan Paull recognize the transformative potential of basalt-based concrete in advancing sustainable construction practices. The adoption of this technology holds the promise of rapid acceptance within the industry, akin to past transitions in other sectors.
C-Crete Technologies’ commitment to leveraging abundant, locally sourced materials as cementitious binders underscores its dedication to eco-conscious manufacturing. Founder and President Rouzbeh Savary emphasizes the company’s mission to utilize naturally occurring resources, such as basalt and zeolite, to drive the widespread adoption of cement-free concretes, thus contributing to a greener future for construction.
