Cement Dioxide produces next-generation SCMs that don't just reduce carbon — they actively remove it from the atmosphere, transforming the construction industry from within.
Our materials lab — where earth science meets climate action.
Cement is one of humanity's most essential materials and one of its most carbon-intensive. At Cement Dioxide, we've developed a proprietary family of supplementary cementitious materials that go beyond low-carbon — our SCMs actively sequester CO₂ during curing, creating structures that lock carbon away for centuries.
Founded by materials scientists and climate engineers, we sit at the intersection of geochemistry, construction, and climate technology. Our mission is to make net-negative concrete the industry standard.
Every product backed by peer-reviewed research and third-party lifecycle analysis.
Designed to integrate into existing supply chains with no new equipment required.
Full EPD documentation and carbon accounting for every product we produce.
Net-negative performance without compromising compressive strength or longevity.
Our SCMs combine mineral carbonation, bio-based pozzolans, and advanced calcination to create binders that sequester more CO₂ than they emit across their full lifecycle.
We accelerate the natural process of mineral weathering, binding atmospheric CO₂ into stable carbonates that persist for geological timescales within the concrete matrix.
Agricultural and forestry byproducts transformed into high-reactivity pozzolanic materials, displacing Portland cement clinker while sequestering biogenic carbon.
Proprietary kiln processes that produce reactive SCMs at temperatures 40% lower than traditional cement, dramatically reducing process emissions at the source.
Our end-to-end process is designed for transparency, traceability, and drop-in compatibility with existing ready-mix operations.
We partner with agricultural processors and mineral quarries to collect and certify raw input streams.
Proprietary low-temperature processing transforms raw feedstocks into reactive SCMs with verified carbon content.
Each batch is tested against ASTM/EN standards and issued a digital EPD with full carbon accounting.
SCMs ship directly to ready-mix plants and precast facilities — no new equipment or process changes needed.
Every tonne of our SCM used in place of Portland cement clinker delivers measurable, verifiable climate impact.
Net CO₂ sequestered per tonne of SCM, certified across full lifecycle
Our SCMs replace 20–50% of Portland cement clinker in standard mix designs with no reduction in 28-day compressive strength, meeting ASTM C618 and EN 450 specifications.
Every product ships with an Environmental Product Declaration (EPD) generated from third-party LCA, compatible with LEED, BREEAM, and Embodied Carbon in Construction Calculator (EC3).
If our SCMs replaced 20% of global clinker production, the resulting sequestration would represent over 800 million tonnes of CO₂ per year — equivalent to removing 170 million cars from the road.
Mineral carbonation improves long-term microstructure density, enhancing resistance to chloride ingress and sulfate attack — concrete that lasts longer also sequesters carbon longer.
Whether you're a ready-mix producer, a developer targeting low-carbon specifications, or an investor in climate materials — we'd love to hear from you.
