Paper Title:
Experimental Test of Corrosion-Induced Concrete Cover Cracking Pattern
  Abstract

The study of cover cracking pattern can provide scientific basis for the durability assessment and maintanence of concrete structures. In this paper, corrosion induced cover cracking pattern was investigated by accelerated corrosion test. The cover thickness c, bar diameter d and bar spacing s were considered in the test. Test results showed that the cracking pattern of cover concrete mainly included four typies, that is longitudinal cracks including wedge and vertical, parallel cracks, spalling and delamination. When the bar spacing was small enough, the delamination of cover concrete occurred which had nothing to do with the ratio c/d. When c/d≤1, the corrosion of side bar mainly induced the vertical cracks and the corrosion of corner bar induced both vertical and wedge cracks. While c/d>1, the corrosion of corner bar mainly induced wedge cracks.
