Ключевые слова:clinker, gypsum, phosphoric slags, mineral additives,, Portland cement, strength, surfactants
This research work is aimed at introducing surfactants into the cement grinding process that contribute to improving the strength characteristics of cement and increasing the productivity of cement mills. In order to fully manifest the hidden astringent properties of granular electrothermophosphoric slags, they need special additives-activators (some alkalis, sulfates, Portland cement or a mixture of these substances). Depending on the type of additive, alkaline, sulfate and combined methods of slag excitation are distinguished. Modern knowledge and experience of construction, observation of cement hardening processes allow us to assert that it is impossible to create universal cement suitable for service in any conditions. In this paper, the issue of increasing the productivity of the mill, increasing the strength characteristics and utilization of chemical industry slags is solved.
