Characterization of magnesium potassium phosphate mortars blended with fly ash and diatomite
Original language description
As the amount of municipal solid waste incinerated increases, so does the output from the combustion process. This includes also ash from flue gas scrubbing, which may pose a risk to the environment and human health if improperly managed due to the heavy metals (HMs) and chlorine (Cl) which it often contains. To utilize the increasing amount of municipal solid waste incineration fly ash (MSWIFA) and simultaneously reduce its environmental impact by immobilizing the present pollutants, a new matrix based on magnesium potassium phosphate cement (MKPC) and diatomite was investigated in this paper. MSWIFA and diatomite were first characterized and then added to MKPC in the amounts of 10 wt.% and 20 wt.%. The basic structural and mechanical parameters of the hardened mortars were determined. Atomic absorption spectroscopy (AAS) was used to analyze the leachates from the hardened mortars to assess the immobilization of As, Pb and Zn. For all the HMs studied, the results showed excellent immobilization capability of the developed mortars, although a decrease in their mechanical properties was observed. Nevertheless, the MKPC-diatomite based mortars formulated with MSWIFA exhibit promising properties for use in the construction industry.
