Deterioration of Concrete due to Acid Rain Attack in North China

Abstract:

The deterioration of concrete under the acid rain and freeze-thaw co-existed environment was investigated in laboratory. The results show that the deterioration caused by acid rain attack is aggravated by freeze-thaw damage in north China and increases with the increase in acidity of acid rain solution and mechanical loading. The SEM results demonstrate that the aggravation results from the cooperation of freeze-thaw damage which accelerates the expansion of the micro-cracks of concrete so that the penetration of erosion media in acid rain solution into the internal pores of concrete is intensified.
