Beschreibung
Zusammenfassung:	A raw mix for the production of portland cement mix consists of a limey component, a clayey component, an ironcontaining component, and a modifying additive comprising hydrolysis and yeast production waste liquors and products of neutralization of chlorine-containing off-gas of the titanium and magnesium production, with the following proportioning of the components (% by weight): limey component 50-52 clayey component 7.5-10 iron-containing component 1-1.5 hydrolysis and yeast production waste liquors 30-38 products of neutralization of chlorine-containing off-gas of the titanium and magnesium production 1-9 The raw mix according to the invention exhibits improved physicochemical and mechanical properties. Fluidity of the mix is from 58 to 60 mm, the degree of decarbonization is as high as 18%. Clinker prepared from the mix according to the invention has a strength from 550 to 560 kgf/cm2 and the roasting temperature is 80-140.degree.C lower.
