LEARNING OBJECTIVES
By the conclusion of this article, the reader should be able to understand the following:

• What microbially induced corrosion (MIC) is, its causes and the microbial processes that lead to concrete’s deterioration.

• The conditions where MIC is most likely to occur, particularly in sewer systems and wastewater treatment plants.

• How MIC affects the structural integrity of concrete, compromising its durability and leading to costly repairs if not properly managed.

• How crystalline technology reduces concrete permeability, making it more resistant to chemical attack, and how combining it with a potent antimicrobial offers a dual approach that effectively protects concrete against MIC and provides significant cost savings on maintenance and repairs in corrosive environments.
