For the expansion of the production Fauji Cement Company built a second kiln line. At this occasion Fauji Cement Company also invested in a SpectraFlow online analyzer and a pre-blending software to optimize its stockpile blending as in the expanded operation both lines...
The «acceleration by retardation» concept is to make an admixture composition that will accelerate the setting of Portland cement by retarding two other processes; dissolution of gypsum and retardation of C3A hydration by another admixture than gypsum. Small dosages of ...
Composite cements consisting of CEM I Portland cement and 30 % replacement by mixtures of calcined clays and limestone have been studied. The calcined clays were prepared from kaolinite and smectitic clay by heating to the minimum temperature needed for complete deh...
The processes that take place during the heat treatment of secondary kaolins from three deposits were examined. It is shown that the temperature required for metakaolin production depends on the chemical and mineralogical composition of the source kaolin and the degree ...
The paper deals with issues of suction in closed cycle cement ball mills, and its effect on the kinetics of the process of grinding. A computational model predicting the particle size distribution of powders along the mill barrel depending on the suction mode is propose...
The results of the study of structural and rheological properties of suspensions prepared from monomineral clayey and carbonate raw materials, forming the raw cement slurry. The selective action of the lignin-alkaline agent on the clayey components of the cement slurry ...
Particle size of cement powder is a key factor that affects the properties of cement. In this paper chemical and mineral compositions of narrow particle size fractions are investigated, and the strength of cement pastes of different specific surface area and narrow part...
Using thermogravimetric analysis and IR transmission spectroscopy the influence of highly disperse amorphous aluminium hydroxide on the hydration of Portland cement. It was found that the reduction of setting time of cement paste with the addition of Al(OH)3 is ...
The education of qualified personnel is a permanent challenge among the cement manufacturers. The need to reduce production costs and at the same time maintain a good product quality requires permanent training. Especially young co-workers joining the cement industry ne...
