Performance
Performance
Karbonite delivers exceptional material performance — even under extreme climatic and environmental conditions.
Mechanical Properties
- Compressive strength >60 MPa (after full carbonation)
- Tensile strength up to 5 MPa | Flexural strength up to 8 MPa
- Thermal conductivity: 0.35 W/m·K, suitable for passive house applications
Durability
- Resistant to freeze–thaw cycles (validated under Central Asian climate conditions)
- Low porosity: no water absorption required during curing or in use
- Carbon-reactive hardening: material continues to strengthen when exposed to CO₂ and thermal variation
Raw Material Independence
- No river or quartz sand required
- No clean or potable water required - can be mixed with seawater or treated industrial wastewater
- Ideal for arid climates and water-scarce regions

Environmental Comparison: Karbonite vs Portland Cement
Indicator | Portland Cement | Karbonite |
CO₂ emissions (net) | +800 kg per ton | −143 kg per ton |
Energy use | ~160 kWh per ton | 132 kWh per ton |
Avoided CO₂ (vs. Portland baseline) | – | ~800 kg CO₂ per ton |
Removed CO₂ (via mineralisation) | – | ~143 kg CO₂ per ton |
Total climate benefit | – | ~943 kg CO₂ per ton |
Every ton of Karbonite delivers up to 943 kg of climate-positive impact, making it one of the few construction materials that actively reverse emissions instead of just reducing them.
Karbonite is more than a product. It’s a movement.
Scientific Validation & Testing
Karbonite has been independently tested and validated by leading institutions and laboratories across Europe and Central Asia.
Key Protocols & Standards:
● ASTM C1157 (performance-based hydraulic cement standard)
● EN 197-1 (common cement specification)
● ISO 14067 (carbon footprint of products – LCA-based)
● EN 12620:2021 (aggregates in concrete – compliance for biogenic alternatives)
Analytical Techniques Used:
● XRD (X-ray diffraction) – confirmed formation of nesquehonite and amorphous silica
● SEM (Scanning Electron Microscopy) – revealed low-porosity structure and dense microstructure
● TGA (Thermogravimetric Analysis) – quantified CO₂ uptake per kg and hydration phases
● BET analysis – demonstrated surface area performance of the silica phase for pozzolanic reactivity
“Karbonite’s microstructure, carbonation depth, and thermal stability have been benchmarked against both traditional Portland cement and next-generation LC3 binders.”
