SULFURIC ACID CORROSION RESISTANT CONCRETE-BASED PIPE, SULFURIC ACID CORROSION PREVENTION METHOD OF CONCRETE-BASED PIPE AND CORROSION PREVENTION METHOD OF STEEL BAR
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
【課題】従来技術とは異なる新たなアプローチで、耐硫酸性コンクリート構造物、特に、下水管用に好適な硫酸腐食耐性コンクリート系管、コンクリート系管の硫酸腐食防止方法及び鉄筋の防食方法を提供する。【解決手段】導電性物質を内在させてセメントが固化してなるコンクリート系管であって、電子放出菌の活動の際に生じる電子を前記導電性物質を通して空気中の酸素に供給することを特徴とする硫酸腐食耐性コンクリート系管とした。また、導電性物質を内在させて固化してなるコンクリート系管内において、電子放出菌の活動によって電子を生成させ、前記電子を前記導電性物質を通して空気中の酸素に供給することで、硫酸（Ｈ２ＳＯ４）の生成を抑制し、コンクリートの腐食を防ぐことを特徴とする、コンクリート系管の硫酸腐食防止方法とした。【選択図】図６
