The present invention relates to a corrosion-resistant hume tube and a method for producing the same, which comprises agitating a mixture comprising fly ash, blast furnace slag, silica fume, fine aggregate, coarse aggregate, water reducing agent, water, and fiber, adding an activator to the mixture, The corrosion resistant concrete composition produced by re-stirring the added mixture was placed in a hume pipe mold and the hume pipe mold was rotated to produce a corrosion resistant hume pipe, thereby preventing the slump degradation due to silica fume and the degradation of the workability by the activator It is possible to provide a corrosion-resistant hume pipe of a closed structure which is not corroded by hydrogen sulfide in the sewage and has a low lifecycle cost but is excellent in strength and cracking than a general portland cement hummer pipe. |
