Abstract Soda residue is the waste discharged from the production of soda ash by ammonia method, its storage and discharge had caused serious environmental problems. The washed soda residue and dechlorination soda residue with lower chloride ion content were obtained by the process of removing chloride ion from the original soda residue. The influence of original soda residue, washed soda residue and dechlorination soda residue on the properties of mortar,and the feasibility of the dechlorination soda residue used as mortar water retention agent were studied. The results show that all types of soda residue replacing 15% of fly ash are conducive to improve the water retention of mortar, but the original soda residue and washed once soda residue may cause durability problems because the higher chloride ion dissolution content. The dechlorination soda residue will not cause durability problems and can be used as mortar water retention agent. When the dechlorination soda residue was used as water retention agent, the mortar had excellent water retention and mechanical properties, and lower shrinkage values. The preferred application way of dechlorination soda residue is replacing parts of the fly ash in the binder, keeping the water binder ratio constant and adding water reducing agent to adjust consistency, and organic water retention agent is not needed.
