RAW MIX FOR PRODUCING PORTLAND CEMENT CLINKER

摘要

RAW MIX FOR PRODUCING PORTLAND CEMENT CLINKER 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.
