Original Abstract

The aim of this work was to prepare alkali-activated matrices of sufficient strength based mainly on ash, to reveal the method of fixation of lead in these matrices and to determine the impact of added lead on mechanical properties. The matrices consisted mainly of ash with a mixture of blast furnace slag and sodium water glass as an activator. Five different ashes were used – four of them were from fluidized bed coal combustion and one from pulverized coal combustion. After 28 days, the strengths of the samples were measured to reveal an impact of lead doping. To determine the structure, images, element maps and elemental spectra were taken using a scanning electron microscope with energy dispersive spectroscopy, the samples were analysed on an infrared spectrometer with Fourier transform, X-ray diffraction analysis and electron spectroscopy for chemical analysis were also used. Individual measurements show that lead is accumulated in the form of hydroxide. The impact of lead doping on strength of the matrix was different for individual samples.
