【 摘 要 】

As the urban population increases and the level of social life advances, the amount of wastewater originating from houses, institutions and industries increases as well. It is necessary for the infrastructure systems in settlements to be sustained under healthy conditions. Since the subsequent repair of infrastructure systems is difficult, appropriate selection of the materials used in these systems is of importance. Concrete pipes are widely used in sewerage systems. In the present study, it was aimed to improve the biological corrosion resistance of concrete pipes via coating with various materials. For this purpose, firstly mortar samples were coated with epoxy, crystalline insulation mortar, and polyester. Finally this specimens subjected to 0.1, 0.5, 1, and 1.5 mol sulfuric acid solutions for 7, 14, 21, 28, 35, and 42 days. It was observed that the coating materials significantly improved the biological corrosion performances of the mortar samples.
