clinker

1. n. a mistake; (in music) a misplayed note. Look at the score, man! That series of clinkers just isn’t there.
2. n. a worthless person or thing. (From the term for a cinder.) Ralph has turned out to be a real clinker. We’ll have to pink slip him.

Engineered cements from the raw materials to finished products are only possible given an improved understanding of the structure and properties of clinker phases, the influences of the calcium sulfate forms, and the effects of supplementary cementitious materials.

Sulfoferrite clinker based on the pure components was presented sulfoferrite calcium and Belita (Fig.
Thus in this clinker is present in a large amount is not metabolized anhydrite (d = 3,50; 2,85 [Angstrom]).
Sulfoferrite clinker based on man-made materials are also designed to receive sulfoferrite calcium and Belita was presented single phase (Fig.
Anhydrite in the clinker at the same temperature and aging present in much smaller amount in comparison with the clinker based on the pure components.
Based on the fact that the phase structure of clinker based technogenic materials differed sharply from the phase structure of clinker on the basis of pure components to study the laws of phase formation in the synthesis of SFC based on secondary raw materials made a series of isothermal sintering in the temperature range 600- 1500[degrees]C in steps of 50[degrees]C.
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.
The purpose of this study was to conduct a petrographic characterization of the natural clinker produced by spontaneous combustion of coal beds Cerrejon Formation and to apply the Rietveld method to the quantitative phase analysis of this geological material.
Petrographic analysis of different samples of natural clinker were carried out to establish their textural and structural features as well as their mineralogy, using the following analytical techniques: transmitted light microscopy (Nikon triocular microscope, model Labophot2-POL) of the School of Geology and image analyzer Leica of the School of Metallurgical Engineering and Materials Science at the Universidad Industrial de Santander, and scanning electron microscope ZEISS EVO50 of the Research Center of Applied Sciences at the University of Wolverhampton (analytical conditions: EHT = 20.
The preparation and assembly of natural clinker samples for X-ray diffraction (XRD) was carried out at the Laboratory of Structural Chemistry of the School of Chemistry at the Universidad Industrial de Santander.
One of the most remarkable features in the areas of Cerrejon coal mining complex is the occurrence of natural clinker as an indicator of ancient fires produced by spontaneous combustion of coal seams (Candela & Quintero, 2004; Quintero et al.
