|Title||The Influence of Surface Coating Materials in Reducing the Corrosion of Steel Reinforcement in Concrete|
|Title in Arabic||تاثير مواد الطلاء الابوكسية في تقليل صدا الحديد في الخرسانة|
This study examines the impact of Epoxy materials to minimize the corrosion of steel reinforcement through test program within three types of Epoxy materials that have been painted on the rebar and choose the best type of surface coating in minimizing the corrosion rate of steel reinforcement. It also studies of the impact of this surface coating on the bonding strength between the rebar and the concrete on the one hand, as well as their impact on the flexural strength on the other hand. The study seeks to fill the gap mentioned by suggesting more methods to improve the bonding between steel reinforcement and concrete. Testing program was set up on the two main phases. The first phase included tests to choose the best material from surface coating within three types of materials are used and the most prevalent market, while the second one covered making the necessary improvements to increase the flexural strength in addition to increasing the bending forces. The corrosion rate result for reinforcement in beams without surface coating after 70 days was more than 50% from its weight. However, the corrosion rate result for reinforcement in beams with surface coating type (C) "Polyurethane resin" after 70 days was 1.6 % from its weight that is the best surface coating. Experiments show the need to use surface coating and admixture to minimize the corrosion rate and improve the flexural strength and bonding between concrete and steel reinforcement.
