A conveyor analyzer AGP-K is described, which operates by the tagged neutron method and makes it possible to obtain data on the elemental composition of the material on the conveyor every 40 seconds. Technical characteristics of the analyzer are given and its advantages...
The article is focused on the current problem of recycling phosphogypsum, one of the many types of industrial wastes generated in large amounts at OAO Gomel Chemical Plant. The authors present the results of studies of artificial gypsum rock production by neutralizing v...
The aim of the research was to study the influence of high calcium ash (HCA) of thermal power plants of different composition and properties on deformation of cement-ash stone hardening in the autoclave with steaming under a pressure of 2.1 MPa. Statistically si...
The article describes Sinoma's experience in mod-ernizing production at the Martes Tolosane cement plant in France, owned by the Holcim group. In spite of all the difficulties, such as cramped space, con-struction in the conditions of the running production, limitat...
A brief analysis of grinding equipment used for grind-ing materials in the cement industry is presented. It is expected that in the coming years ball drum mills will remain the main grinding unit in large-tonnage pro-duction. One of the main directions of improvement in...

The purpose of the research was to determine the effect of limestone as a mineral additive in cement on frost resistance of hardened cement. The structure and properties of materials have been studied us-ing methods of X-ray phase and differential thermal analysis, scan...
Concrete road pavements have an increased dura-bility. In Russia and many other countries the share of roads with such pavements in the total length of the highways under construction is increasing. The main disadvantage of concrete pavements is limited maintainability....
Portland cement and blast furnace slag compositions for cementing medium and low activity liquid radioactive waste concentrates in large volume receptacles have been investigated. The possibility of cementation of both high-salt solutions and concentrated suspensions is...
It has been established that granulated blast-furnace slag improves the structure of the problem cohesive soils increasing their density and strength. It was shown that the use of fine ground granulated blast furnace slag (GGBFS) in combination with Portland cem...
