What is albedo of concrete?

Albedo is a measure of how much sunlight is reflected by a surface, expressed as a fraction or percentage. The albedo of concrete typically ranges from about 0.3 to 0.5, meaning it reflects 30% to 50% of incoming solar radiation, depending on factors such as color, texture, and moisture content. Lighter-colored concrete generally has a higher albedo, which can help mitigate urban heat effects.
