摘要
试验证明了污水中好氧菌对混凝土产生的腐蚀作用 ,叙述了好氧菌的代谢物———有机酸以及呼吸作用排出的碳酸是引起混凝土腐蚀的主原因。掺混合材料的混凝土受污水侵蚀的程度要小些。
It has been proved by test that the aerobes in the sewage can make the ordinary concrete deteriorate but if the concrete is mixed with some additives together with admixture, the antibiosis of the concrete can get better. At the same time it is described that the metabolites of the aerobes——the organic acid and the carbonate acid produced by respiratory action are the main reasons let to concrete deterioration.
