Huseyin, SARICIMEN SULFATE AND ACID RESISTANCE OF MATERIALS FOR USE IN SEWAGE AND WASTEWATER TRANSPORT SYSTEMS IN SAUDI ARABIA - A REVIEW. Calcium Aluminate Cements: Proceedings of the Centenary Conference.
Concrete and metallic structures in sewer transport systems in the Eastern Province of Saudi Arabia showed signs of severe deterioration within 3 years into service. Several investigations were carried out to determine the corrosivity of the sewer environment and severity of material degradation in the sewer systems. At the same time studies were conducted to find corrosion resistant materials and coating suitable for use in sewer environments. In this paper a review of the findings of these investigations is given. Several different materials, such as high performance coatings, fiber glass reinforced linings, special mortars, brick or ceramic linings, etc., ar used to protect concrete from sulfuric acid attack in a sewage environment. Two proprietary high alumina cementitious lining materials, SC and CC, are recent additions to the list of protective materials used in the Arabia Gulf. This report documents the findings of a laboratory study under accelerated conditions in addition to a two-year field study in a wastewater pump station in Jubail, Saudi Arabia. Performance of the liner materials at the wastewater pump station was monitored for sulfate content and alkalinity after 6, 12, and 24 months of exposure. The analysis and evaluation test data generated from the accelerated lab study and the field study showed that SC performed, superior to CC within the test conditions used in this investigation.
