Calculation of the raw material mixture for the production of sulfoferrite clinker produced by glandular and sulfate modules and characterizing the resulting SFC mineralogical composition, namely basicity sulfoferrite calcium and its percentage with respect to belite [2, 11].
Maximum firing temperature sulfoferrite clinker based on man-made materials became the temperature to 1350[degrees]C.
The phase structure of the obtained spec clinker was investigated by X-ray analysis on the instrument ARL X'TRA.
Sulfoferrite clinker based on the pure components was presented sulfoferrite calcium and Belita (Fig.
Different blending ratios between oil shale ash and ordinary Portland cement were used in this study to determine the possible blending ratio with normal clinker raw materials for further processing without affecting the properties.
At temperatures between 1300 and 1350[degrees]C, it is clear that a blending ratio of 10 to 15% could be used in making clinker materials.
Up to 15% of oil shale ash can be used with a typical Portland cement clinker without affecting the main properties of the cement.
Compositional Analysis of the NIST Reference Material Clinkers, NIST Technical Note, in preparation.
One major achievement in the late 1920s, derived from studies on phase equilibria in cement clinker, allows calculation of potential cement clinker composition.
Klein published the paper "Properties of the Calcium Silicates and Calcium Aluminate Occurring in Normal Portland Cement" (3) which expanded on the research of Rankin and Wright at the Geophysical Laboratory on the constitution of portland cement clinker.
Research efforts of the NBS and PCA fellowship staff helped improve the general knowledge of phase equilibria among the oxides in cement clinker, and also led to additional insight to the limits of solid solution of other oxides in the primary clinker phases.
The determination of mineral phases and chemical composition of natural clinker is vital in resolving problems concerning their genesis, correlation of coal beds, characterization of the protolith and assessment of potential environmental impacts of coal combustion.
The bulk chemical composition similarity of natural clinker with the volcanic materials from which the natural zeolites are originated by post-magmatic hydrothermal activity has motivated attempts of making zeolite from this geomaterial by Rios and co-workers (Rios & Williams, 2008; Rios et al.
Although its potential application might consume only a small part of the natural clinker produced by coal combustion, end products could reach a much higher added value than that currently presenting this geomaterial in the coal industry of Colombia.
Quantitative analysis by the Rietveld method (Rietveld, 1969; Young, 1993) has huge advantages over traditional methods using integrated intensities of a small set of reflections in limited angular intervals, since the overlap of the lines of a pattern of powder diffraction, especially in mineralogically complex samples such as the natural clinker, make it virtually impossible to carry out a rigorous analysis by conventional methods.
