| Abstract Scope |
Low energy production of strong, carbon-negative construction materials would be essential in addressing the climate crisis. While incorporating biomaterials reduces carbon emissions, these products are not water-resistant and require a protective layer. Here, we introduce an Enzymatic Structural Material (ESM) that employs a capillary suspension combined with an enzyme mixture to integrate precipitated calcium minerals into a sand and carbon matrix. ESM shows high water stability compared to other biologically inspired construction materials with a mechanical strength close to the compressive strength of structural concrete (26 MPa), making it a promising candidate for construction applications. Importantly, ESM production consumes 8.5 kg of CO2 per m3, unlike traditional concrete production, which emits approximately 400 kg of CO2 per m3, aligning with the need for low-carbon building solutions. Physical characterization of ESM confirms its promise as a structural material for advancing sustainable construction technologies. |
