Concrete remains the backbone of global construction, but the main concern is how to reduce the reliance on high clinker cements - historically associated with significant CO2 emissions. The scarcity of traditional SCMs such as fly ash has left manufacturers looking for alternatives that are not only renewable but also scalable. Our C/CLAY solution offers a new way forward with calcined clay, a widely available and underused resource that can be processed with exceptional efficacy.
Where C/CLAY stands out is in its precision engineering. Through controlled calcination, this technology converts standard clays into highly reactive, pozzolanic materials that perform on par with traditional cements. By replacing up to 50% of clinker, C/CLAY reduces carbon output by 40%, but also bypasses the rising logistical costs of sourcing SCMs from across the globe. More importantly, it integrates into existing cement production lines, minimizing CAPEX while optimizing fuel and operational efficiency.
But it's not just the environmental benefits that matter, it's the practical application: Clay is abundant and globally available, providing a reliable alternative to increasingly scarce materials such as fly ash.
Our C/CLAY technology, also improves the properties of concrete, such as chloride resistance, for long-lasting structures. Co-grinding calcined clay and clinker in vertical roller mills uses 25% less energy and results in a 7% increase in compressive strength. This technology is both a compromise and an evolution in the way we approach cement production.

9moTough to get excited about watching concrete, but in this case I’ll make an exception. 😎. Nice work
