    Abstract

    Most concrete pipes of 915-mm diameter buried 1.5 m below the surface of Kuwait highways have been examined. About 55% of these developed circumferential strains (in tension) about 30 microstrain at top and bottom as soon as they were buried. In a matter of eight weeks, due to vehicle loads, the top strains increased on 100 pipes by 10% and bottom strains remained unchanged. An experiment has been carried out on site to determine the magnitude of the creep occurring in such pipes. In a period of six months the creep strains have increased by three times the previous strains resulting from the initial application of loads. Over 60% of the concrete pipes tested show 4.75 times creep strains measured at the initial stages. On King Faisal Road some pipes on removal indicated a substantial degradation of material due to sulfur attack.
