The laboratory investigation on the autogenous and total shrinkage of high strength concrete, and the ways of its reduction, are presented. Such concretes demonstrate significant autogenous shrinkage, which should, however, be limited in the early stages of its developm...
In nine months of 2016 7,007 kt of cement and 4,838 kt of clinker were produced, or, respectively 7.8 % and 14.6 % more than in the same period for 2015. In September 2016 there were produced 2.8 % of cement and 1.0 % of clinker more than in September 20...
This article describes an approach to multipleoption designing of process equipment for Portland cement production lines, with a case study of ball mills. Modern software makes it possible to create digital mock-ups of items and combine different components of units to ...
The effect of additives obtained by grinding granulated slag on hydration and early compressive strength of slag Portland cement was examined. Grinding of granulated blast furnace slag with addition of sodium aluminate accelerated hydration of Portland cement component ...
The use of Portland cement in the world has grown exponentially in recent years. There is a relationship between this material and the economic and social development, especially in development countries. The predictions are that consumption will be 40 billion tons per ...
Computer study of Portlandite carbonization reaction was made using density functional theory (DFT). Also an experimental investigation of Portlandite carbonization was performed at low relative humidity (40%). Two cycles of a change of regime from c...
The article presents a review of the presentations made at Cemtech Conference held in Madrid, Spain, on September 18—21, 2016.
