Analysing the Effect of Chloride Penetration on Corrosion
Session
Civil Engineering, Infrastructure and Environment
Description
This experimental study is to evaluate the influence of various factors on the acceleration of steel reinforcement corrosion in concrete exposed to chlorides. The study focuses on chloride ingress through controlled cracks introduced in the concrete, simulating real-world damage conditions in reinforced structures. The main variables investigated include the type of concrete, the type of reinforcement (with or without epoxy coating), the concrete cover thickness, and the presence of cracks. A total of 162 cylindrical specimens (100 × 120 mm) with reinforcement were prepared, along with 24 additional specimens (150 × 300 mm) without reinforcement for compressive strength testing. Several tests were applied: the pull-out test to create controlled cracks, the chloride test to see the penetration of chloride, the split test, the half-cell potential test, and the compressive strength test. Preliminary results indicate that cracking significantly increases chloride ingress and poses a greater risk of reinforcement corrosion in reinforced concrete.
