ABSTRACT:
IR reflective cementitious systems comprising one or more IR reflective pigments are provided. The 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 are provided. The cementitious systems are infrared reflective and may be toppings mixed with water for application to existing concrete surfaces, or dry-shake hardeners for application to freshly-placed plastic concrete. The formulations of the invention utilize one or more of cementitious binder(s), graded aggregates, super-plasticizers, one or more pigments selected for improving infrared reflectivity and color composition, and/or optionally other additives, such as dry redispersible polymers or fillers to provide decorative and LEED compliant, highly durable (sustainable) concrete hardscapes and other decorative concrete.
