Abstract：Stabilization for soda residue with ground granulated blast furnace slag(GGBS) and cement was discussed.The waste residue was located in Beijiang distinct of Tianjin port.An optimum proportion was obtained by fuzzy evaluation method and the compressibility test for the solidified soda residue under the optimum proportion was carried out.The results show that under the same curing agent content,the unconfined compressive strength of stabilized soda residue with mixture curing agent is stronger than that with single curing agent;both of the compression coefficient and compression index of stabilized soda residue are decreased with increase of curing age,while the yield stress is increased.Due to the great change of compressibility of stabilized soda residue at the post-yield state,it is suggested that the upper load should not exceed the structural yield stress to prevent sudden damage.
