Abstract

Iron (III) arsenate and some other arsenates have a much lower solubility in an alkaline environment, that is, it is advisable to store and use these wastes together with compounds that provide an alkaline reaction. Cement is characterized by high pH values, and the content of arsenic in cement is not normalized, because the human body does not directly contact with cement. The experimental results proved that utilization of arsenic-containing adsorbents in the form of concrete products was safe in case of arsenic content from 53.3-142.2 μg/g and had perspectives in colouring of concrete products.
