Title: High Albedo and Environmental-Friendly Concrete for Smart
Growth and Sustainable Development
Ohio Northern University students will investigate solar reflective properties (albedos) of conventional concrete and design new concrete mixtures that have higher albedo values, yet are affordable, environment-friendly, durable, structurally sound, and esthetically acceptable. These new concrete mixtures will utilize a high proportion of Portland cement replacements, thus reducing greenhouse gas emissions produced by the cement manufacturing process. Their higher albedo values will also help mitigate "heat island" effect in urban areas, resulting in savings in cooling costs and improved air quality.
