The invention discloses environment-friendly concrete. Pollutants including formaldehyde, NOX, SO2 and the like in outdoor air are effectively removed through a catalytic reaction of nano titanium white under the action of natural light and physical adsorption of active carbon with high specific surface area; the removal efficiency is further improved through adding a foaming agent, quartz sand and ultrafine slag powder, so that the pollutants above are effectively and efficiently removed, the pollution is reduced and the environment is protected; the environment-friendly concrete can be widely applied to outdoor building construction.
