【Abstract】 In this paper, the change of atmospheric environment and compositions of atmospheric pollutants were discussed. Both the carbonated mechanism for concrete by CO₂, HC1, SO₂ etc., containing in pollutants and the changing relation of carbonated depth with time were analyzed. The main factors affecting carbonization were analyzed as well. According to carbonization principle and prediction of atmospheric environmental change, the carbonization depth of reinforced concrete structures in future 50 years was analyzed and some suggestions on design of durable R. C. structure considering atmospheric pollution were presented.更多还原
