Abstract

The paper presents chemical, physical, and physicochemical investigations of sewage sludge and iron-oxide pigments produced therefrom. Gravimetric, X-ray phase, and thermal analyses and scanning electron microscopy were carried out in certified laboratories. Experimental results are given for iron-containing sewage sludge produced by the water-treatment plant and taken from water collection filters of Tomsk groundwater sources. It is shown that at heating ironcontaining sewage sludge up to 800 °c, a brick-red pigment is formed having the specific surface area of 9.8 m2/g that corresponds to the theoretical particle size of 124 nm. A flow-chart is suggested for the production of iron-oxide pigments obtained from sewage sludge, and the raw material compositions are designed for construction industry applications. The suggested cementsand colored compositions of materials and products have passed the evaluation tests at OOO Akvatom (Tomsk, Russia), and their high service properties (strength, water- And frost-resistance) are experimentally supported.
