Experimental Research on the Durability of Inorganic Binder Stabilized Material with Soda Residue

Abstract:

The high contents of alkali ion and chloride ion in soda residue pollute environment. So how to treat the soda residue is an urgent problem to be solved in China. The soda residue can be used in inorganic binder stabilized materials. But the negative effect of soda residue is not studied. The impermeability, frost resistance, and chloride ion leaching of inorganic binder stabilize materials prepared by soda residue are studied. And the results as followings: (1) The permeability coefficients of cement/ mineral admixture-soda residue stabilized stone chip are very low, and they are good impermeable materials; (2) The frost resistance of cement-silica fume-soda residue stabilized stone chip is good, and silica fume is recommended to be used in cold area; (3) The mineral admixture has a better long-term immobilized effect on chloride ion than cement, and the ground granular blast-furnance slag is the best mineral admixture to immobilize the chloride ion.
