Abstract
Physical Sciences Inc. proposes to electrophoretically deposit a coating of lithium silicate and photoactive titanium dioxide nanoparticles onto concrete providing a totally inorganic, room-temperature cured, concrete sealant. This coating scheme will be shown to not only reduce water permeability but will also benefit from the antimicrobial properties of the reactive titanium dioxide nanoparticles. The photoactive nature of the titanium dioxide will inhibit bacteria, mold, fungus, and algae growth on the concrete surface providing added long-term benefit. Phase 1 will validate the advantages of the proposed method via reduction in water permeability and demonstration of the anti-microbial functionality of the coating.
