C-Crete Technologies

C-Crete Technologies is a materials science company founded in 2010 and headquartered in San Leandro, California, developing cement-free concrete binders. It addresses the carbon footprint of Portland cement, one of the largest industrial sources of CO2 emissions, by replacing it with binders synthesized from natural rock and industrial by-products.

The company’s zeolite-based binder is produced at lower processing temperatures than Portland cement and is mixed with standard aggregates to produce ready-mix concrete with comparable strength and durability. C-Crete supplies its material and mix designs to ready-mix concrete producers and contractors for infrastructure, commercial and federal construction projects.

1. Cement-free binder: zeolite-based material replaces Portland cement in concrete mixes.

2. Low processing temperature: binder synthesis avoids the high-heat kiln step used for cement.

3. Comparable performance: mix designs matched to standard concrete strength requirements.

4. Large-scale deployment: over 4,000 tons placed across airport, data centre and federal projects.

5. Ready-mix compatibility: material integrates with existing ready-mix concrete production lines.

6. Natural feedstock: uses granite, basalt and industrial by-products instead of mined limestone.
