Abstract:
The sanitary engineering structures covered by this article are tanks, pipelines, and tunnels holding and conveying domestic and industrial sewage and potable water. The article describes the fundamental requirements for resistance to corrosion in these structures. Details are given of the basic properties of portland cement, aggregates, and reinforcement which help to ensure long term durability in reinforced concrete structures. The need to assess as accurately as possible the corrosion hazards when the structures are in contact with aggressive environments is discussed. Information is provided on the principles of protection for new structures and techniques for dealing with deterioration in older structures.
