Better cement

OPUS SCM™ replaces historical SCMs at scale, including fly ash. Drop-in. Cost-competitive. Consistent, increased performance.

The future of cement is here.

High performance, a fraction of the carbon, and a solution that holds up in the boardroom as well as on the build site.

the road to zero

Two products.
One mission.

Decarbonizing cement

Terra’s mission is to decarbonize cement—paving the way for truly net zero construction.

OPUS SCM™

A low-carbon, engineered supplementary cementitious material (SCM) that partially replaces Portland cement in the concrete mix—cutting CO₂ out of every pour.

  • Up to 50% Portland cement replacement
  • 50–70% lower embodied CO₂
  • Available mid-2027
