Cemenon geopolymer concrete for zero-cement high-durability infrastructure
Zero-Portland-cement geopolymer concrete using alkali-activated polymerization of fly ash/metakaolin, achieving high acid resistance (17x conventional) and ~75%+ CO2 reduction.
Problem solved
Portland cement production accounts for ~8% of global CO2. Cemenon eliminates cement entirely, using industrial byproducts (fly ash, metakaolin) polymerized with alkali solution. High acid resistance solves sewer corrosion, a major infrastructure cost driver.
Application contexts
- Sewer infrastructure (acid-resistant)
- Shield tunnel segments
- Industrial flooring (chemical plants)
- Precast concrete products
Technical principle
Alkali-activated polymerization: aluminosilicate powders (metakaolin, fly ash) react with alkaline solution (water glass) forming a geopolymer binder. No cement clinker required. Adjustable filler/aggregate for tailored performance (neutron shielding, freeze-thaw resistance).
Typical use cases
- Sewer pipe and tunnel segment replacement with acid-resistant geopolymer
- Carbon-neutral precast concrete products for infrastructure
- Chemical plant flooring requiring high acid resistance
