Abstract
Corrosion of the reinforcing steel in reinforced concrete will effect its structural performance. This is in two ways: loss of steel section and deterioration of steel-concrete bond. In this, bond effects are investigated using two methods for different influences. The first technique looks at the effect of spalling concrete. This would affect bond by lessening the confinement. This is simulated by debonding proportions of the perimeters of steel bars in a reinforced concrete member and testing in flexure. The second looks at the effect of corrosion products. This was accomplished by casting reinforced concrete slabs with the ends of the reinforcing bars anchored in the concrete for a known length; the centre portion unbonded. The ends were corroded to various corrosion levels and then tested in flexure. Also included is a test of the predictive power of this work.
