“…Ancak artan çamur oranıyla birlikte seramik ürünlerdeki gözeneklilik de artmış, bu durum da fiziksel ve mekanik özelliklerin azalmasına neden olmuştur. Ham yüke ağırlıkça %5'e kadar yapılan çamur ilavesinin fiziksel ve mekanik özellikleri olumsuz yönde etkilemediği ve elde edilen ürünlerin ısı yalıtım malzemesi olarak kullanılabileceği sonucuna varılmıştır [39].…”

Endüstriyel faaliyetler sonucu oluşan arıtma çamurlarının geri kazanımı, arıtımı veya bertarafı tüm dünyada en önemli çevresel sorunlar arasındadır. Atık çamurların yönetiminde yaygın olarak kullanılan yakma, depolama, susuzlaştırma veya tarım alanlarında kullanma gibi yöntemler bu atıkların içerisindeki ağır metallerin uzaklaştırılmasında yetersiz kalmaktadır. Bu atıkların çevre için risk oluşturması ve arıtma maliyetleri gibi sorunların yanı sıra doğal kaynakların da her geçen yıl azaldığı düşünüldüğünde, oluşan atık çamurların değerlendirilerek ikincil malzemelere dönüştürülmesinin önemi artmaktadır. Bu bağlamda vitirifikasyon yöntemi, atıklardan yapı malzemeleri (cam-seramik, tuğla, pigment vb.) üretmenin yanı sıra atıkların içerisindeki ağır metallerin stabilizasyonunu da sağlayan, döngüsel ekonomi yaklaşımıyla örtüşen bir yöntem olarak dikkati çekmektedir. Bu makalede, endüstriyel artıma çamurlarının katma değeri olan ürünlere dönüştürülmesi noktasında, arıtma çamurlarının vitrifikasyonu ve vitrifiye ürünlerin kullanım alanları ile ilgili çalışmalar incelenmiştir.

“…At the same time, the volume coloring of the product, especially in the case of obtaining saturated color tones, requires an increased consumption of coloring additives, which increases its cost. Reducing the cost of the product in this case is possible due to the use in the compositions of the masses of man-made wastes containing in enough quantity color-forming oxides necessary to give the material the desired color [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The choice of pigments is determined by the properties of the pigment and material, the nature of their interaction, as well as the processing parameters and operating conditions of the products.…”

The paper presents the results of investigation concerning using a high-temperature pigment based on synthetic tri-manganese tetra-oxide (Mn3O4) in the production of volume-colored bricks using red-burning clay. It is established that the introduction of a pigment in the amount of 2–4% results in a rich dark brown brick. At the same time, the intensity of the color increases with an increase in the pigment concentration from 2 to 4% and a brick firing temperature from 800 to 950°C. It has been established that with the introduction of pigment the strength of the obtained brick samples decreases, as well as the frost resistance.

The paper considers the ecological problems of water conditioning systems at heat power industry facilities. It is noted that the stable operation of water-heating equipment is provided with the quality of feed water. Various water-soluble salts, which can incrust the inner walls of boilers or pipelines, are removed from the natural water. For desalination of natural water the physical-chemical methods are mostly used. The by-product of desalination or chemical water-conditioning systems is the sludge waste. This work presents the results of using chemical water conditioning sludge from JSC Verofarm in the raw charge for wall ceramics production. The sludge is a finely-divided powder, the mineral composition of which is presented with calcium and magnesium carbonates, brucite and iron compounds, which make the sludge pink. It has been determined that the baking of sludge-containing ceramic samples at temperature 1000°C results in dissociation of calcium and magnesium carbonates with the formation of gaseous products H2O and CO2, which make the structure of ceramic materials porous. The presence of iron compounds in the raw charge promotes the formation of low-temperature silicate melt, which intensifies the baking process of ceramic samples. The optimal sludge content in the charge that doesn’t reduce the strength characteristics of wall ceramics is 10%. Such sludge content forms the liquid phase on the surface of the raw mix’s particles, which solidifies the forming pores. The increase of sludge content up to 20% intensifies gas generation; the amount of the formed liquid phase is not sufficient, which increases porosity and reduces the density and strength of ceramic materials. At that, the engobe layer is formed on the surface of the obtained wall ceramics samples. The wall ceramics products, obtained with the use of chemical water conditioning sludge, can be used as structural heat-insulation materials in making building envelopes or interior partitions.
