Abstract

It has been established that during heat treatment of mixtures of waste activated sludge (WAS) and Fe2O3 under the conditions of oxygen deficiency at 800–1000 °C, reactive carbon, which initiates the reduction of Fe2O3 to Fe and the formation of C–FexOy mixtures, forms. Based on these compacted mixtures, having different electrical resistivity (from ~ 10–4 up to 10–1 Ω·m), it is possible to fabricate heating elements, whose working temperature ranges from ~ 100 °C up to 600 °C. Such heating elements can be used in the construction industry to accelerate the curing of concrete and its low temperature heating.
