“…As electroplating sludge refers to 2-3 hazard class [2], and boric acid to the 3-d class the research has been carried out for the assessment of environmental safety of the produced ceramics according to determination method of Daphnia magna Straus mortality under the impact of toxic substances in the daily aqueous extract from the researched samples [5].…”

“…The report authors previously conducted research for the developing the charge compositions on the basis of low-plasticity clay from the Vladimir region, using galvanic sludge for producing environmentally safe construction ceramics [1][2][3][4], thus allowing to expand the regional raw material base and to solve the toxic waste disposal problem. In the current research ceramics ecologic safety, endurance and frost resistance were provided by the introduction of boric acid together with the galvanic sludge into the charge, which forms an amorphous vitreous phase, filling the pores and voids in the material during its firing.…”

“…In the current research ceramics ecologic safety, endurance and frost resistance were provided by the introduction of boric acid together with the galvanic sludge into the charge, which forms an amorphous vitreous phase, filling the pores and voids in the material during its firing. Vitreous phase prevents heavy metals migration when ceramics is contacting water and simultaneously binds the particles of the material [2]. To increase ceramics endurance and frost-resistance the amount of the formed vitreous phase was increased and self-glazing effect on ceramics surface due to additional introduction of glass crash [3] or titanium dioxide [4] at firing temperature of 1050 о С enhanced.…”

Abstract. The paper presents research results concerning charge composition development to produce environmentally safe acid-resistant ceramics on the basis of low-plastic clay of the Vladimir region possessing self-glazing effect. 5 wt. % boric acid, 5 wt. % lanthanum oxide and up to 5 wt. % electroplating sludge have been introduced into the charge composition as functional additives. Boric acid serves as a flux and a source acid-resistant and heat-resistant vitreous phase based on borosilicates, but compositions contained in the electroplating sludge are decomposed in the process of ceramics firing causing the formation of calcium oxide and heavy metal oxides, which additionally increase material acid-resistance and heatresistance like lanthanum oxide. To receive the developed material, semidry pressing technology has been applied under the charge forming moisture of 8 wt. %, specific pressure of 15 МPа and one-stage firing at max temperature of 1050 о С. The research presents the testing results of ceramics principal operating properties and environmental safety. The developed material can be used in clinker and acid-resistant bricks and tiles production for masonry and tiling in aggressive environment like buildings foundations and bases, premises with high moisture, as well as in sewerage systems, chimneys and ventilation ducts.

Abstract. The research presents the results of the charge development for producing ceramic composite material, where ceramic particles of the crystalline structure serve as filler, and vitreous amorphous phase obtained by the introduction of the cullet and the flux into the charge at different firing temperatures serve as a binder. Herewith the cullet is used as a fluxstrengthening additive, which is a source of vitreous phase, and the flux reduces the amount of the formed vitreous phase. Boric acid, feldspar, and dolomite separately have been used as fluxes in the current research. In the conducted experiments, the charge basic component was low-plasticity clay, which can be used for producing high quality products only with the introduction of functional additives. Basing on the obtained data, it has been stated that higher values of strength and lower values of water absorption for the developed material can be achieved at the introduction of 30 wt. % of the cullet and 2.5 wt.% of boric acid as a flux at the highest firing temperature of 1050 o C. The developed charge composition facilitates broadening the construction materials production resource base due to the usage of low-demand low-plasticity clay and glass works waste. The material produced on the basis of this charge corresponds to the requirements for the construction materials used for indoor and outdoor facing of facades, socles of the buildings and facilities.
