Reflective surfaces (climate engineering) - Wikipedia

Reflective surfaces can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the surface) and high thermal emittance (the ability to radiate absorbed, or non-reflected, solar energy). Reflective surfaces are a form of geoengineering.. The most well-known type of reflective surface is the "cool roof".

Concrete as Solar Reflectance Material - cement.org

Concrete does a very good job of reflecting solar energy. That is the finding from a Portland Cement Association (PCA) study which measured the solar reflectance index (SRI) of 45 concrete mixes. Lighter colored materials (such as concrete) generally have a higher solar reflectance. They reflect heat from the sun and do not warm the air very much.
