Concrete pressure pipe performance in acid soils
Investigations were conducted concerning the effects on cement‐mortar‐coated pipe under long‐term exposure in naturally occurring acid soils. Two existing pipelines were excavated and measurements were made of soil pH, total acidity, and resistivity; pipe potentials with respect to a copper sulfate electrode; and the extent of soil acid attack on the mortar coating. At each test station sections of the mortar coating were removed and the circumferential reinforcement and steel cylinder were examined. Long‐term degradation of mortar coatings and their corrosion inhibitive properties were inconsequential in the pipelines investigated.
