Ah, well that's an interesting phenomenon, Citizen Koala. Concrete is made from cement, which has a high iron content. When light hits concrete, the iron absorbs many spectra of it, while other elements in the concrete reflect it. All frequencies that the human eye interprets as color are absorbed, while some white frequencies is returned.
