Development of sustainable coating to prevent concrete corrosion

In North America, more than 75 percent of the population is served by wastewater collection systems and treatment plants for which concrete is a key construction material. Unfortunately, thousands km of lines must be removed each year for replacement suffering from corrosion which caused by prolonged exposure of concrete surface to highly aggressive environments. Concrete corrosion in these environments is mainly caused by the diffusion of aggressive solutions and in situ production of sulfuric acid by microorganisms which affect the properties of concrete resulting in aesthetic, functional and structural problems. Over the past several decades many approaches were attempted to prevent concrete corrosion with varying degree of success. Therefore, developing innovative and sustainable coating material for construction and repair could be a long term solution for enhancing concrete pipes durability as well as decreasing the risks associated with contamination of surrounding environment.
