Not just a greener SCM — A better one
OPUS SCM™ outperforms fly ash—at equal or lower cost, with a fraction of the carbon.
WHY CHOOSE OPUS SCM™
Mixes, places, and finishes just like you’re used to.
Better than fly ash.
OPUS SCM™ replaces more Portland cement than fly ash and other legacy SCMs—at comparable cost, with higher and more consistent performance. Unlike traditional waste stream fly ash, it’s manufactured through a controlled process, delivering consistent chemistry and predictable performance, every batch.

WHY CHOOSE OPUS SCM™
Six reasons to specify OPUS SCM™
Performance to spec
Meets compressive strength, durability, and workability requirements across common mix designs. Performs with all Portland cement types, including Type 1, 2, 1P, 1L, and 1T.
Cost-competitive
Competitive against fly ash on commercial terms—before green premiums or government incentives. The business case doesn’t depend on subsidies.
Drop-in ready
Works within existing concrete infrastructure, supply chains, and production processes. No new mines.
Locally produced
Plants sit on small footprints, designed to be built close to core markets. Shorter distances = lower transport costs + lower CO₂ emissions.
Solves the supply gap
Fly ash is disappearing as coal plants close. OPUS SCM™ is locally manufactured from silicate rock—90% of the Earth’s crust.
Built for long-term durability
OPUS SCM™ can refine pore structure, reduce permeability, mitigate ASR, and improve other durability measures, such as sulfate and chloride corrosion.

The opportunity
Don’t just buy it. Make it.
You can access the technology to produce OPUS SCM™ in your own market, using your own raw materials. Here’s how.
Evaluate your feedstock
Terra’s raw material testing program assesses whether your local silicate rock, aggregate, or waste stream is suitable. Most are.
License the technology
License and royalty model. Plant built and commissioned in 12-14 months on a small footprint, close to your market.
Produce locally
Manufacture OPUS SCM™ at scale using your feedstock. Sell into your existing market with lower transport costs and a verified low-carbon product.
De-risk with proven tech
Terra is building its first industrial-scale plant right now. You’re adopting a proven, certified, commercially deployed technology.
WHAT OUR CLIENTS ARE SAYING
Our partnership with Terra marks the beginning of meaningful change in the construction industry. As plant #1 comes out of the ground at our Cleburne TX terminal, we are already looking to add five more facilities in Texas over the coming years. Local supply greatly reduces logistics costs, vehicles on the road, and greenhouse gases, and we are proud to be leading the charge.
