Description
Coatings composed of carbonated silicate minerals (C3S, C2S, C3S2, CS) that form dense structures and provide protective effects for concrete while capturing CO2. These coatings offer good strength and durability through volume expansion during carbonation.
Market positioning
Emerging technology focused on concrete protection and CO2 sequestration
Use cases
Construction industry, concrete protection specialists, and sustainable building material companies
Features
Excellent protective effect on concrete
Good bond strength (demonstrated >60 MPa strength)
CO2 capture and sequestration
