Abstract: Sustainable wastewater infrastructure systems are vital for civilizations to protect public health. Most of the structural elements of wastewater infrastructure are constructed using concrete owing to its versatility, low cost, and durability. Concrete structures that are exposed to wastewater can experience Microbially Induced Corrosion of Concrete (MICC), which is a multi-stage biodeterioration process. The service life of concrete wastewater infrastructure can be significantly shortened by MICC with considerable associated costs for repair and rehabilitation.
MICC is a multi-disciplinary subject that draws on civil engineering, environmental engineering, material science, and microbiology. The complex nature of MICC has made its comprehensive investigation difficult because of the challenges associated with creating the field conditions in laboratories. Therefore, although MICC has been studied for over 70 years, there is still a need for realistic tests methods to assess MICC in laboratory settings. The primary goal of this thesis is to develop practical laboratory test protocols to assess the performance of concrete against MICC.
