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

Abstract:

The soda residue pollutes the environment because of high contents of alkali ion and choleric 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 to improve the strength performance of inorganic binder stabilized materials and decrease the negative effect of soda residue is studied. And the results as followings: (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 choleric 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-furnance slag is the best material to improve the strength performance of inorganic binder stabilized materials and decreases the negative effect of soda residue.
