Although reinforced concrete is one of the most durable construction materials, in farm buildings it is subjected
to high levels of hydrogen sulfide and sulfate that result in corrosion. This leads to premature deterioration of
slatted floors and other concrete components of liquid manure storages. The rehabilitation of reinforced
concrete structures due to corrosion is expensive and impractical. Prevention is the better approach.
Hazardous gases are released from stored manure. Of these, hydrogen sulfide is the most corrosive. Sulfatereducing
bacteria generate sulfuric acid as the end of their metabolism
