Title: Process for obtaining health- and environment acceptable construction materials from the soil containing water soluble compounds of heavy metals
Description: The invention refers to a process for obtaining health- and environment acceptable construction materials from the soil containing water soluble compounds of heavy metals, which are harmful for health and environment and the content of which essentially exceeds still acceptable border values. During the first step such contaminated soil is prepared, upon which a dispersion of Fe nanoparticles is admixed to said soil, which is then followed by adding of bentonite clay in powder form and homogenization. Upon that, calcareous fly ash is added, which is optionally followed by adding water and mixing.
