Abstract

This study is to specify the properties of solidification/stabilization of heavy metals in connection with looking over the hydration features of non-sintering cement using industrial by-products. In this study, we added Cr and Pb to non-sintering cement(NSC), ordinary portland cement (OPC), and Blast-furnace slag cement(BSC) to specify the solidification process. Heavy metal leaching test was carried out to evaluate solidification degree of various cement. Follow result, marking no higher than 0.7% of un-solidified ratio of BSC was the most predominant result when we mixed the materials with Cr. 5.8% for NSCI and 6.2% for NSC2. On the contrary, in case of adding Pb, NSCl and NSC2 made better solidification results than those of OPC(below 0.2%) and BSC(below 0.05%), marking nearly 0%.
