The article provides a description of the work of OAO “GiproCement" on the development of the dry process for cement production, the completed projects and those under development. Specifics of the design work on cement production facilities using equipment of West...
The structure of the laboratory at the OOO Krasnoyarsk Cement, fitted with modern equipment is described along with methods and instruments for testing, current and future challenges, and changes in the organization of control in the enterprise.
Increasingly the cement industry is adopting laser diffraction particle size analysis. Unlike Blaine analysis, laser diffraction delivers a size distribution for the sample, rather than a single averaged figure. This makes it the more sensitive technique for characteriz...
In the article the issue of applicability and relevance of use of foreign standards in the domestic practice of construction, engineering and construction materials production is raised. Trends and possible consequences of mandatory introduction of European standards ar...
A better understanding of the cement hydration evolution and of the development of cementitious materials microstructure at early age is very important for improving concrete durability. The microstructure, which depends on various factors (water-cement ratio, curin...
The article presents the results of a study of cement hydration, using ESEM electronic microscopy, quantitative X-ray phase analysis and other experimental methods, and a qualitative pattern of hydration developed from experimental data.
It was established that the addition of 1% of the electrolytes with highly charged cations and anions (Fe2(SO4)3, Al2(SO4)3) helps to increase the activity of Portland cement stored for 23 months in an unheated room. In this case, the compres...
In paper technical-economical analysis of energo-saving up provisions is resulted at reception of the cement clinker, not connected with considerable holdings on manufacture modernisation. Methods of decrease in moisture content of a raw sludge, a heading of the equipme...
The Cinar company has provided technical assistance to many cement plants in issues related to making better use of different fuels, examining aerodynamic simulation of processes occurring in kilns and calciners during fuel combustion. The article examines the factors a...
The article discusses the influence of the characteristics of white Portland cement, aluminous and high-alumina cement on the properties of mixed compositions and materials on their base.
