Reinforced concrete hume pipes have been widely used as drain pipes. However, many reinforced concrete hume pipes are exposed to the deteriorated environments such as freezing-thawing damage, chemical attack and chloride ion immersion by using sea sand. The purpose of this study is to improve the durability of reinforced concrete hume pipe by using the polymer cement slurry(PCS)-coated rebar and treating the surface by polymer cement mortar(PCM). From the test results, it is apparent that PCS-coated rebar has a excellent resistance to chloride ion penetration and the PCM has good mechanical properties and durability as a lining material for reinforced concrete hume pipe product.
