Research on the Proportion of Inorganic Binder Stabilize Materials with Soda Residue

摘要

The soda residue pollutes the environment because of high contents of alkali ion and chloride ion in it. So how to treat the soda residue is an urgent problem to be solved. The mineral admixtures are added in traditional inorganic binder, and the strength performance and the negative effect of inorganic binder stabilized materials with soda residue is studied. And the results as follows: (1) Soda residue has different activated effect on mineral admixture;;(2) Mineral admixture replace the cement with same dosage can improve the unconfined compressive strength greatly to meet the requirement of standard;;(3) The chloride ion leaching rates of cement-mineral admixture-soda residue stabilized stone chip decrease with time. Mineral admixture has a better immobilization effect on the chloride ion except fly ash before 90d;;(4) Ground granular blast-furnace slag is the best material to improve the strength performance of inorganic binder stabilized materials and decreases the negative effect of soda residue.
