| Abstract [eng] |
The stabilisation of aggressive technogenic waste in cement systems is a reliable technology to reduce toxicity and mobility of waste. Although this method is effective, it is rarely used in the Republic of Lithuania's waste management system. The objective of this project is to analytically and experimentally assess the mechanism and effectiveness of aggressive technogenic waste stabilisation in cement systems. The objective was achieved by determining the mechanical, physical and chemical properties of the stabilized system. The compressive strength and density of the system is investigated to be increased, while concentration of technogenic waste in cement system is increasing up to 10%. After completing the (Fe, P, Cr, Cu, Mn, Ni, Zn) leaching experiment, we found that wastes are the most stable, while containing 5% concentration in the system. The dispersion of the experiment data obtained was best matched by the parabolic dependence, with corresponding second-degree plural equations. The bondage and results can be adapted by tentatively assessing the potential for the stabilisation of aggressive technogenic waste in cement systems. |
