| Abstract Scope |
Carbon-negative emission enzymatic construction materials have attracted significant attention recently due to their potential for sustainable and environmentally friendly building practices. The effort of the durability of biological construction materials still remains largely elusive. We present a novel approach to developing a scaffold using capillary suspension, which utilizes capillary forces to concentrate particles in a liquid matrix. we harness Carbonic anhydrase, a zinc-containing enzyme extracted from bovine erythrocytes, to grow mineral materials. Specifically, we demonstrate the use of capillary suspension to create a construction material scaffold consisting of sand and polymer, providing 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 than traditional ECM with decent mechanical properties, making it a promising candidate for construction applications. The net carbon dioxide of ECM-σ during production consumes 51 kg one cubic yard. |
