In order to study the effect of steel bars rusting and swelling on compressive strength of concrete under current action,the adding of direct current was adopted to prepare rusted expansive concrete specimens,the cracking process and failure pattern of concrete under different current intensity corrosion were comparatively analyzed,and the change law of the compressive strength of concrete under the condition of rusted steel bars inside concrete was studied.The results showed that under the condition that steel bars are accelerating corrosion,the compressive strength degradation process of the...
