The article considers the possibilities and effectiveness of application of the calorimetric analysis method for studying the technological process characteristics of cement, concrete mix and concrete. Calorimetric data formed the basis of the thermokinetic classificati...
The cohesion of cement grains is caused by surface forces acting between calcium silicate hydrate (C-SH) nanoparticles in interstitial electrolytic solution. The influence of pH, cations valency and concentration on the stability of the final concrete constructi...
In spite of the fact that hundreds of publications are devoted to the problem of alkali-silicate reactions (ASR) in concretes, and practical recommendations have already been worked out for reducing the risk of their origination and development, one nevertheless...
The article cites the results of the works on using gypsum-anhydrite-type rock as cement setting time regulators, the anhydrite differing by the presence of changing, within wide limits, water-soluble and insoluble forms of calcium sulphate. For an additional controllab...
The article cites the results of a study on the efficiency of using artificial gypsum stone obtained on the base of phosphogypsum in the process of Portland cement manufacture. It is shown that, in order to ensure high results, phosphogypsum should be moulded under a fo...
The article considers the possibility of managing the mineral formation process at burning of Portland cement raw charges by dosed thermal action with the use of a new ceramic heat exchanger.
In order to develop a technology of electroconducting composite materials based on cement and graphite, a study was made of the structural-rheological characteristics of graphite dispersions in cement pastes. The article demonstrates the connection between structural-rh...
The article considers the situation in the Russian market of dry construction mixes (DCM) in 2008 and in the first three quarters of 2009. The DCM market growth observed in 2008, in its last quarter and the first half of 2009 was replaced by a slower growth and ...
The article reviews the NPP Dneproenergostal experience in the matter of introducing the specially developed bag filters with pulse regeneration, as well as the results of obsolete electrostatic precipitators reconstruction.
The article presents information on the seminar organised by KHD Humboldt Wedag International — one of the largest suppliers of equipment for the cement sector — for its Russian customers on the island of Tenerife, Spain between September 30 and October 2, 2009.
