The Research of the Waste Sludge with the Content of Hazardous Substances Solidification Using Cement Matrix

Abstract:

This paper deals with the solidification/stabilization of selected type of hazardous waste with use of cementation. Different solidification formulas for this chosen waste were proposed with use of two types of cements and classic and fluid fly ashes. Then according to these formulas testing specimens were produced and after maturing process were subjected to laboratory tests - compressive strength after 28 and 60 days maturing testing and leachability testing. This paper presents results of this laboratory tests.
