THIOBACILLUS THIOOXIDANS GROWTH INHIBITOR CEMENT COMPOSITION AND CEMENT STRUCTURE

摘要

pH is near neutral, as well as, under acidic conditions of below pH4 and can also sufficiently inhibit the thio Bacillus, thio oxy thiooxidans growth, addition of a metal ion eluting This will sufficiently inhibit the active ingredient when blended in a cement structure, over a long period of time to provide the thio Bacillus which effect is maintained and thio oxy thiooxidans growth inhibitor, a cement composition and a cement structure. The inhibitors of nickel phthalocyanine powders, a nickel phthalocyanine derivative powder, and mixtures thereof The first component is selected from the group consisting of and, the tungsten powder, the substantially water-insoluble tungsten compound powder, water soluble and also is substantially water insoluble as when reacted with cement tungstates and that contains a second component selected from the group consisting of a mixture thereof.
