Fluoride mineralizers such as CaF2 are increasingly used in modern Portland cement (Pc) production. Although the bulk fluoride content in the kiln feed is typically only about 0.2%w, it has an important impact on the formation as well as the hydration proper...
On the base of their analysis of the well-known and the present paper authors’ own researches, scientific concepts about the structure of the stones of various binders with physically and chemically active microfillers were developed and the general and particular model...
A method for finding the kinetic parameters of the clinker grinding process in closed-circuit ball mills is proposed, which allows construction of several theoretical curves from one kinetic curve, to obtain characteristics of the disperse state along the barrel of the ...
An experimental setup for studying the processes of heat exchange in the layer of the clinker grains with forced air filtration system is defined allowing to study heat transfer between the granular material and air at high temperatures and characterized by a low loss o...
The article deals with preconditions for optimal designing of building blends compositions in order to obtain concrete on the cement binding based on polydisperse structures formation regularity including microlevel. The choice of methods for modeling granular loose sys...
The process of clinker production at the Chełm cement plant of Cemex Co. located in Poland is described. Alternative types of fuel used in clinker production and their burning are discussed. The amount of heat produced by the company from alternative fuels is about...
The use of alternative fuels at cement plants in Russia and the CIS countries is an issue of the near future. The article outlines possible ways of implementing projects to use alternative fuels on the basis of long experience of MHC Engineering Foerdertechnik GmbH, Ger...
The laboratory studies demonstrated the possibility of using wastes from iron-vanadium production as an iron-containing component of the cement raw mix. The effect of iron-containing wastes on the formation of clinker phases, microstructure of clinker, the hydraulic act...
Rapid destruction of pavement concretes is due to a combination of mechanical and environmental impacts, exacerbated by the use of defrosting agents. Freeze-thaw resistance of concrete in aqueous solutions of defrosters is dependent not only on the parameters of porosit...
The production technology of metakaolin to be used as a cement replacement material complying with the European and Egyptian standard specifications is being studied in Egypt. Kaolin quarried from different locations was characterized chemically, mineralogically and its...
