Beschreibung
Zusammenfassung:	A raw mix for the production of portland cement mix consists of a lime component, a clay component, an iron-containing component, and a modifying additive comprising hydrolysis and yeast production waste liquors and products of neutralization of chlorine-containing off-gas from titanium and magnesium production, with the following proportioning of the components (% by weight): lime component 50-52 clay 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 from titanium and magnesium production 1-9. The raw mix according to the invention exhibits improved physico-chemical 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 of from 550 to 560 kgf/cm2, and the roasting temperature is 80 DEG -140 DEG C. lower.
