Effect of passive confinement provided from Engineered Cementitious Composites (ECC) cover on corrosion of steel reinforcement
Publication details: Thane ACC LTD 2019Edition: Vol.93(12), DecDescription: 10-18pSubject(s): Online resources: In: Indian Concrete Journal - ICJSummary: This paper investigates the effect of passive confinement provided from ECC cover on corrosion of steel reinforcing bars. ECC and fibre-reinforced concrete (FRC) with different fibre dosage are used as cover materials to provide different levels of passive confinement to the steel reinforcement subject to corrosion. Results showed that specimen with ECC cover showed significant performance improvement with reduced mass loss and mass loss rate of steel reinforcement and increased residual flexural load capacity. The fundamental change of failure mode of cover material from brittle to ductile is the key to enhance the corrosion resistance in R/C.| Item type | Current library | Status | Barcode | |

This paper investigates the effect of passive confinement provided from ECC cover on corrosion of steel reinforcing bars. ECC and fibre-reinforced concrete (FRC) with different fibre dosage are used as cover materials to provide different levels of passive confinement to the steel reinforcement subject to corrosion. Results showed that specimen with ECC cover showed significant performance improvement with reduced mass loss and mass loss rate of steel reinforcement and increased residual flexural load capacity. The fundamental change of failure mode of cover material from brittle to ductile is the key to enhance the corrosion resistance in R/C.
