Abstract:

High SRI cementitious systems comprising integral concrete coloring admixtures, toppings, dry-shake hardeners, and other cementitious systems are provided. The high-SRI cementitious systems comprise one or more IR reflective pigments and other components to make-up the cementitious system, depending on the application. The high-SRI cementitious systems of the invention may be in the form of mixtures which increase the total solar reflectivity (TSR or albedo) and the Solar Reflectance Index (SRI) of concrete. The high-SRI cementitious systems may be toppings mixed with water for application to existing concrete surfaces, dry-shake hardeners for application to freshly-placed plastic concrete, or the IR reflective pigments may be mixed into integrally colored concrete in various forms, such as conventional cast-in-place concrete, lightweight concrete, pervious concrete and concrete building panels, pavers or masonry units.
