Abstract: 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/cm.sup.2, and the roasting temperature is 80.degree.

Abstract: According to the invention, the raw mix for producing portland cement clinker comprises a lime component, a clay component, an iron-containing component and a modifying agent. The latter is a cake byproduct readily available at titanium and magnesium works. The percentage by weight composition of the mix is as follows:______________________________________ lime component, 88.3 to 77.8 clay component, 9.2 to 11.2 iron-containing component, 2.0 to 5.0 modifying agent, 0.5 to 6.0 ______________________________________The raw mix according to the invention possesses better properties than conventional mixes. For example, its plasticity is 140 to 160 units, and the degree of mineralization is as high as 19 percent.

Abstract: A graphitization and reducing charge intended for thermal processing of carbon and graphite products consists of 85 to 95 percent by mass of coke containing not less than 90 percent by volume of size fraction ranging from 0.5 to 2 mm and not more than 10 percent by volume of size fraction ranging from 2 to 10 mm and of 5 to 15 percent by mass of sawdust.The graphitization charge, after having been subjected to not less than 2000.degree. C. in the graphitization oven, may be used as a reducing agent in ferrous and nonferrous metallurgy. As a reducing agent it possesses greater reactivity than known reducing agents, since its oxidation capacity is 54%.The use of the aforesaid charge provides a means to economize coke which is a scarce carbon material.
