富里酸环境下粉煤灰水泥土的腐蚀性试验研究
Corrosion Test of Fly Ash Cement Soil with Fulvic Acid
摘要
Abstract
Studying the durability of cement soil in corrosive environment is of great significance to the safety of building structure.Fly ash, as an important admixture of civil engineering materials, can reduce the amount of cement used and can improve the workability of cement soil mixing, is widely used in practical engineering.In order to study the corrosion of cement soil mixed with fly ash in humic acid environment, according to the environment of peat ( soil) in Kunming, this paper simulated the corrosive environment by using laboratory tests, and mixed pure fly ash with fly ash of cement soil immersed in fulvic acid environment, through the immersion process apparent changes in two groups of samples, acid consumption and corrosion softening depth comparison of pure cement and fly ash mixed cement soil in the fulvic acid environment corrosion in the changing conditions.The results show that cement-soil mixed with fly ash deteriorates more seriously in the fulvic acid environment.Considering the long-term safety of building structure, cement-soil structures in humic acid environment should not be mixed with fly ash.关键词
