Abstract

When investigating the action of microscopic fungi of genera Aspergillus, Alternaria, Cladosporium and Paecilomyces on concrete specimens in the model system, it was shown that the fungi can colonize successfully the concrete surface during 1 year and cause its destructive changes. However the fungi did not colonize those sections of concrete surface which were filled with granite. The fungi leached chemical elements of concrete into nutrition medium, accumulated them in their biomass and caused their transformation into newly-formed crystals of calcium oxalates on the surface of concrete.

摘要

在模型系统中研究曲霉属、链格孢属、枝孢属和拟青霉属的微观真菌对混凝土试件的作用时发现，这些真菌能够在1年内成功定殖于混凝土表面并导致其发生破坏性变化。然而，真菌并未定殖于填充有花岗岩的混凝土表面区域。真菌将混凝土中的化学元素沥滤到营养培养基中，在其生物量中积累这些元素，并导致它们在混凝土表面转化为新形成的草酸钙晶体。
