This study discussed about the pollution due to the ecosystem on the concrete surface. The concrete surface was decaied in the order of the higher humidity and the shading green algae. The black ecosystem substance as like Clisterium sp. etc. grow well at the a higher humid and shading place. The increment of ecosystem substance independed on the neutrality of concrete, that would be depended the environment of the concrete.
