Correlation of tensile strength and corrosion initiation period of reinforced concrete

Service life of reinforced concrete constitutes initiation and propagation period. Tensile strength is among the mechanical hardened properties of concrete that influence the corrosion initiation. This research work examines the relationship between split tensile strength and corrosion initiation pe...
