Unlike SCM-only strategies, deltaC adds biogenic carbon storage in a liquid drop-in format and lets producers retain environmental attributes, without a hefty green premium.
Glossary
Shared definitions for ΔC, digitalΔggregate, and related mix-design terms.
- ΔC
- alterBiota's carbon-negative liquid admixture made from stranded biomass, and the world's first liquid biochar admixture for concrete. Permanently stores ~10–18% of mix GWP as biogenic carbon (30–50 kg CO₂e/m³), enables ~5–10% cement reduction, improves performance, and delivers >20% lower embodied carbon without plant changes.
- digitalΔggregate
- alterBiota's computer vision platform for real-time aggregate quality intelligence, helping quality and production teams monitor material variability with mobile and continuous imaging alongside required physical testing.
- Sand Replacement (SR)
- Mix design strategy where biochar solids volumetrically replace a portion of fine aggregate while keeping mortar volume constant.
- Cement Replacement (CR)
- Mix design strategy where ΔC enables partial Portland cement reduction while holding powder volume constant.
- GWP
- Global Warming Potential, the embodied carbon typically reported as kg CO₂-eq/m³ for concrete (A1–A3).
- SievEQ
- digitalΔggregate capability that predicts sieve-equivalent gradation from imaging data.
- StoneSight
- digitalΔggregate static imaging analysis for particle shape, size, and distribution.
