Improvements made by Austrian Unitherm Cemcon to its M.A.S. rotary kiln burners, aimed at optimizing the combustion of solid secondary fuels with low NOx emissions, raising the burner efficiency and facilitating its maintenance, are considered. Several examples of succe...
Curved belt and pipe conveyors for cement industry developed and produced by BEUMER Group of companies (Germany) are reviewed. With these pipelines bulk materials can be quickly and efficiently transported over rough terrain. An example of the pipe conveyor belt...
Physical and chemical studies of the effect of iron oxides on the hydrolytic stability of clinker minerals and cement and the concrete obtained from them were made. The specifics of these processes in cements obtained from clinkers burned in rotary kilns together with s...

Water physical properties of chalk suspensions depending on the microstructural characteristics of the rock and the presence of thinners at OOO Polyplast Novomoskovsk were examined. It is shown that the microstructure of chalk particles occurring at the lower horizon is...
The work reviews the transformation of silica-containing additives (silica fume, metakaolin, precipitated SiO2, and low-calcium fly ash) in the cement stone and cement-sand mortar, aged in tests according to the method close to GOST 8269.0 (a method of testi...
The possibility of using sulfoferrite clinker synthesized from metallurgical wastes as an expanding component for non-shrinking and expanding cements was established. The effect of trace elements contained in the wastes on the processes of mineralization in sulfoferrite...
Pozzolanic properties of pure kaolinitic clays are widely proved, but natural clay deposits present several impurities: illite, quartz, anatase and feldspar, and the prediction of its pozzolanic properties are poorly investigated.
The purpose of this investigation is to...
An assessment of the results of the dry mixes market of Russia on the basis of data for 9–11 months in 2012 is given. The growth rate of dry mixes output in 2012 is close to its growth in 2011.
To ensure the desired application and end-product properties, dry-mortar and gypsum formulations need to be balanced multi-component systems in which each ingredient has to perform reliably. In this investigation, various commercially available gypsum retarders were tes...
On December 10–14, 2012 the 5th International Congress of Cement Producers was held at the Belgorod V.G. Shukhov State Technological University. An overview of the papers presented at the congress is provided.
