Pore-Forming Additives for Ceramic Gravel Production Made of Technogenic Materials

Abstract:

The purpose of the research is to determine the possibility of producing claydite gravel using the technogenic waste - wastewater treatment sludge – as the raw material. In this paper the titrimetric, spectrophotometrical, atomic absorption methods of research are used, the chemical composition of clay and wastewater treatment sludge has been determined. The possibility of using this waste material as an additive for claydite gravel production has been proved. The optimal amount of the wastewater treatment sludge being added to the basic raw stuff has been identified. The negligible extent of heavy metals leaching from the obtained building material has been researched and experimentally proved. The article can be of interest for the specialists in the sphere of obtaining new building materials based on industrial waste and wastewater treatment.
