摘要： PROBLEM TO BE SOLVED: To provide a method of setting anti-corrosion lining not only on a sideways-facing surface but also on a downward-facing surface such as a ceiling, without using timbering.
SOLUTION: According to the method, support members 15 are arranged on an existing concrete surface so as to project from the surface by a predetermined length, and at least a projection end 15a of each support member is formed of an iron-containing metal or a magnetic body, followed by bonding a cement-containing composition to the existing concrete surface such that the projection end is substantially exposed to a surface of the cement-containing composition 11. Then a plate-like anti-corrosion member 12 having protrusions is pressed to the cement-containing composition before hardening to embed and bond the protrusions 12b into the cement-containing composition, and magnets 16 are arranged on an external surface of the plate-like anti-corrosion member at locations opposed to the projection ends of the support member, respectively, to thereby fix the plate-like anti-corrosion member by an adsorption force due to a magnetic force between the magnets and the iron-containing metal or the magnetic body at the projection ends.

摘要： PROBLEM TO BE SOLVED: To provide a growth inhibitor to effectively inhibit the growth of sulfur-oxidizing bacteria and iron-oxidizing bacteria by compounding a small amount of the inhibitor to a concrete or mortar construction of a sewage treatment facility, etc., and suppressing the deterioration of the concrete or mortar construction by the bacteria for a long period, and to provide the concrete and the mortar produced by using the inhibitor.
SOLUTION: The growth inhibitor of sulfur-oxidizing bacteria and/or iron-oxidizing bacteria contains a dicarboxylic acid metal salt and/or a hydroxy acid metal salt as an active component and is usable for the concrete or mortar constructions of the sewage treatment facility, etc.

摘要： Provided is a method that enables simple and quick detection of the addition of a corrosion inhibitor for preventing sulfuric acid degradation, due to microorganisms, of sewer system concrete structures, hume pipes and assembled manholes. The method for simple detection of a corrosion inhibitor is characterized in that a sulfur-oxidizing bacterium having sulfur-oxidizing capability, a culture liquid containing sulfur or a sulfur compound that has been adjusted to a pH of 1 to 4, and a sample that is expected to contain a corrosion inhibitor are mixed, and the resulting liquid is set aside for a specific time and then monitored for color change using a pH indicator in order to detect the presence of a corrosion inhibitor. In particular, the corrosion inhibitor detected is nickel or tungsten and the sulfur-oxidizing bacteria is selected from Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans.
