冻融损伤对引气混凝土中钢筋锈蚀的影响研究
Abstract: In order to study the steel corrosion in the reinforced concrete added with air entraining agent under freeze-thaw environment, and the influence of cover thickness on the steel corrosion, the ordinary reinforced concrete and air entraining concrete with different cover thickness were prepared, and the half cell potential and the linear polarization methods were used to evaluate the state of steel corrosion in different concrete specimens. The results show that the value of half cell potential and the linear polarization both increase with the increase of freeze-thaw cycles, which demonstrates the resistance to steel corrosion decrease. The resistance to steel corrosion of air entraining concrete is higher than that of the ordinary concrete, and the resistance to steel corrosion also raises with the increase of cover thickness.
