摘要

The chemical-mineralogical composition and technological properties of the ceramic production wastes of Kulol JSC, used as a component of the raw mix for the production of Portland cement clinker, have been extensively studied. It was found that full or partial replacement of natural clayey raw material (loess) by ceramic production wastes during firing increases the reactivity of the raw mixes, accelerates the process of CaO absorption and promotes the completion of the mineral formation process with good clinker granulation at a relatively low temperature stage — below 1450°C. Portland cement produced from synthesized clinker is classified as additive-free Portland cement CEM I according to GOST 31108–2020.
