Effect of design parameters on microstructure of steel-concrete interface in reinforced concrete

Porous band at the steel-concrete interface in reinforced concrete can significantly affect the corrosion-induced cracking process of concrete. The quantification of this porous band is of great significance for accurate prediction of service life of corrosion affected concrete structures. In this paper, the effects of concrete design parameters, namely water to cement ratio, aggregate size and concrete cover, on the thickness of porous band at...
