Early deterioration assessment of selected reinforcement in different host environments, case study: Lagos State, Nigeria

Corrosion is known to negatively affect the structural integrity of reinforced concrete structures. In order to manage the effect of corrosion on structures, some preventive measures must be considered. Among such measures is to test the integrity of the reinforcement used. Three high-yield reinforc...
