Abstract:Reinforced concrete pipe used as sewer pipe is required to have excellent durability, especially chemical resistance, in addition to high strength and good economy. A precast composite pipe, in which a reinforced concrete pipe is lined with polymer mortar as soon as centrifugal compaction and drainage have been completed, was developed and investigated. Chemical resistance of the polymer mortar exposed to acidic and alkaline water was studied first by immersion tests and manufacturing process of the composite pipe was introduced next. Subsequently, load tests were carried out and elastic behavior, cracking, and breakable strength of the pipes were investigated. Finally, a reasonable design method for the composite pipe is discussed and proposed.
