Initiation and Propagation of Crack Due to Corrosion of Reinforcement - An Experimental Investigation
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 4
Abstract
In the field of fracture mechanics of concrete as well as for health risk assessment of reinforced concrete structures in marine environment, the initiation and propagation of cracks due to corrosion of reinforcement plays a vital role. In the present study, the location of crack initiation is evaluated experimentally. The thicknesses of rust layer around the reinforcement and width of crack due to this rust formation were also investigated. Accelerated corrosion test were used to furnish the experiment. It was found that the major crack was initiated from the outer surface of the cover concrete and propagated towards the steel reinforcement interface. Corrosion induced crack of width 0.225 mm was caused by a thickness of rust layer of 0.358 mm.
