SULFURIC ACID CORROSION RESISTANT CONCRETE-BASED PIPE, SULFURIC ACID CORROSION PREVENTION METHOD OF CONCRETE-BASED PIPE AND CORROSION PREVENTION METHOD OF STEEL BAR

摘要

To provide a sulfuric acid corrosion resistant concrete-based pipe suitable for a sulfuric acid resistant concrete structure, especially a sewer pipe by a novel approach different from prior art, a sulfuric acid corrosion prevention method of a concrete-based pipe, and a correction prevention method of a steel bar.SOLUTION: There is provided a concrete-based pipe by including a conductive material and solidifying cement, in which an electron generated during actions of electron emission bacteria is supplied to oxygen in air through the conductive material. There is provided a sulfuric acid corrosion prevention method of the concrete-based pipe, in which generation of sulfuric acid (HSO) is suppressed and corrosion of concrete is prevented by generating the electron by actions of electron emission bacteria and supplying the electron to oxygen in the air through the conductive material in the concrete-based pipe.SELECTED DRAWING: Figure 6
