The present research has contributed to an improved knowledge on the incorporation of Al in the C-S-H phase in cement hydration products.The manner in which chain lengths in the C-S-H phase depend on substitution rate of cement by metakaolin has been determined. It has...
The results of rheological analysis of the raw slurry for cement production are given. The examination was carried out using a modern rotary viscometer Rheotest RN4.1. It was found that in the presence of new generation diluents all the rheological properties change: th...
The influence of slag aging during storage in natural conditions, under water and in open air with varying relative humidity on its reactivity is investigated. It is shown that its changes as compared with a fresh sample are negligible.
The article describes the use of a metallic apron extractor from French firm Walter Materials Handling supplying shredded tires for burning in the calciner at the Holcim Apasco plant in Hermosillo, Mexico. Also, the design of the storage facility with an automated orang...
The article contains recommendations for a long-term operation of gas cleaning plants, their reconstruction and modernization in view of modern technical solutions, in order to significantly improve the efficiency of cleaning plants at lower building and operating costs...
This paper describes the progress of the program to reduce dust emissions of the cement plant within the Polar Division of OAO MMC Norilsk Nickel. As part of the program, the outdated electrostatic precipitator was replaced by a modern bag filter, which significantly re...
In this paper the influence of particle size distri¬bution of metakaolin on its ability to prevent the reaction between the cement alkali and silica filler is investigated. Following the procedure of ac¬celerated tests the linear strains in the samples of fine-grained c...
The influence of plasticizers of different chemical nature on the processes of structure formation of alkali Portland cement in the system "Portland ce¬ment clinker - sodium metasilicate - calcium sulfate hemihydrate" was examined, in order to determine the pr...
On April 13—17, 2014 in Washington, District of Columbia (US), under the auspices of IEEE-IAS PCA the 56th International Technical Conference on cement was held. The conference was attended by more than 980 participants from 27 countries. An overview of the pape...
In May 2014 the Nevyanskiy cementnik plant of EUROCEMENT group celebrated its centenary. On May 7, 1914 clinker kilns were launched at the com¬pany, and soon the first barrels of Portland cement were shipped to the consumers of the Ekaterinburg province. For 100 years, ...
