Influence of red mud on electrical resistivity and strength characteristics of loess solidified by cement

In order to study the solidified effect and micro-structural changes of loess solidified by red mud, through adding red mud in the cement stabilized loess, the unconfined compressive strength and electrical resistivity were measured. By incorporating different amounts of red mud in cement soil, the stabilized loess samples were prepared in different dosage of red mud. The resistivity of stabilized loess was tested under different current frequency and curing period for analyzing the microstructure changes of stabilized loess. Simultaneously, the unconfined compressive strength of stabilized loess was tested under different curing period for analyzing the solidified effect of red mud in the cement loess, and find the best incorporation of red mud to help related personnel who engaged in soil solidified by red mud.
