Introduction
Essentially, reinforced concrete is made of concrete and steel. In the Construction industry it is one of the most widely used building materials (Yakut, 2007:1). This is to no small part due to the wide availability of reinforcing steel as well as the concrete ingredients (Yakut, 2007:1). Moreover, Sinha (2002:1) points out that by combining the best properties of concrete and steel reinforced concrete attains high utility and versatility. However, Holland (1997:1) argues that although reinforced concrete structures have shown significant durability performance over the last 50 years, there was currently a global deterioration problem caused primarily by reinforcement corrosion.
As consequence, this report is prepared in order to identify the most common causes of steel corrosion in reinforced concrete, its mechanics and how this process affects its structural performance. Furthermore, this paper will explore certain remedial approaches, as well as preventive measures against corrosion.
