Failure Analysis of Epoxy-Lined Asbestos-Cement Pipe.

Abstract

This report presents the findings of an investigation into the causes of failure of epoxy lining in asbestos-cement sewer pipe used in certain Middle East construction projects. The asbestos-cement pipe passed all tests performed on it to see whether it met the original specifications. The epoxy lining did not meet the requirements in some samples. The report concludes that the lining failures occurred because of the following factors: (1) Poor proportioning of curing agent to epoxy resin, mixing, and curing, which led to residual stresses, large amounts of swelling, softening, and strength loss both internally (cohesively) and at the adhesive bond (adhesively). (2) Environmental effects (high soluble salt content of the soil), and possible aggressiveness of the materials carried in the pipe. (Author)
