Evaluation of the potential of Microwave Plasma–Atomic Emission Spectrometry for trace elements leaching assessment from the concrete matrix with sewage sludge ash additives

Abstrakt

The management of ash generated during the thermal utilization of sewage sludge is a significant environmental problem requiring an effective technological solution. One alternative way to dispose of sewage sludge is to bind it in concrete as a substitute for part of the aggregate. The properties of the C-S-H phase enable effective immobilization of harmful substances that sewage sludge contains. The amount of individual compounds and elements is variable and fully dependent on the characteristics of the wastewater flowing into the sewage sludge treatment plant. The research investigated the effect of the addition of sewage sludge as a replacement for part of the sand, on the fresh concrete mix and the characteristics of the hardened concrete. The behavior of heavy metals were subjected to observation using microwave plasma–atomic emission spectrometer in three environments, such as nitric acid (pH ≈ 3), artificial ground-water and seawater solutions. The validity of using advanced spectroscopic methods, such as mentioned microwave plasma–ato-mic emission spectrometer, for improving the assessment of the danger of using waste materials in modern building materials was considered.
