Carbon negative emission enzymatic construction materials have attracted significant attention in recent years due to their potential for sustainable and environmentally friendly building practices. The effort of the durability of biological construction materials still remains largely elusive. In this work, we present a novel approach to developing a scaffold using the capillary suspension, a technique that utilizes capillary forces to concentrate particles in a liquid matrix. Specifically, we demonstrate the use of capillary suspension to create a construction material scaffold consisting of sand and polymer, which provide nucleation sites allowing carbonic anhydrase to catalyze the calcium mineral growth and aggregate to create a water-resistant construction material, named ECM-σ. The resulting material shows a higher water resistance compared to traditional ECM with decent mechanical properties, making it a promising candidate for use in construction applications. The net carbon dioxide of ECM-σ during production consumes 51kg in every 1 cubic yard. |
