In this paper the test results were presented through which some physical and mechanical and also
environmental properties were identified. The presented results are just a part of number of the tests which were
carried out in order to certificate the solidification products and its future use as technological material to landfill.
All tested solidification products were prepared on the basis of chosen solidification formulas while each formula
contained 50 wt. % NS, two types of fly ash (FA, CA), cement and the solidification product (SP) with designation
7B contained carbide lime instead of the cement.
