The study presents the research results confirming environmental safety of the ceramic material used for construction purposes, produced basing on low-plasticity clay from the Vladimir region with the introduction of 2.5 wt. % boric acid, 5 wt. % of electroplating sludge and 30 wt. % of cullet. The material environmental safety has been previously confirmed by Daphnia mortality method in diurnal water extracts from the chipped ceramic material samples, including possible mechanical damage and deterioration during the operation. The experimental studies embraced the determination of heavy metal ions concentration in diurnal extracts from the chipped ceramic material samples in neutral and acidic media. Additional studies dealing with the heavy metals migration into the extracts were carried out in static mode during 20 days. The research results confirm the environmental safety of ceramic material in neutral and acidic media during the heavy metals immobilization, caused by ceramics self-glazing and vitrification. The research results proved that the production of the developed material will expand the regional raw material base, will contribute to the utilization of large-capacity and toxic waste with simultaneous manufacturing of high-quality and environmentally friendly construction products for new buildings construction or existing buildings and structures reconstruction.
