Abstract
As the pH of NSC paste prepared as an alternative to OPC using industrial byproducts such as GBFS, PG and WL is around 11, it is considered possible to utilize it as cement for solidification in disposing industrial waste. Thus, in order to examine the usability of NSC as cement for solidification in disposing industrial waste, this study evaluated its effect on the hydration of cement and the microstructure of hydrates, and analyzed its mechanical properties. The Cr immobilization rate of NSC hardened cement product for heavy metal Cr was lower than BSC but higher than OPC, and the Pb immobilization rate was highest in NSC regardless of curing age and addition rate. The compressive strength of NSC mortar containing Pb was higher than that of OPC and BSC mortar, but the compressive strength of NSC mortar containing Cr was lower than that of OPC mortar. Considering its mechanical characteristics, NSC may be usable as a solidifying agent for wastes containing a large volume of Pb ions.
