Progress in quantification of clinker phases Premium
The quantification of clinker phases is not always straightforward and often raises a number of questions. However, there has recently been significant progress in this area, as...
Crystal clusters in clinker Premium
With increasing use of alternative fuels, short homogenisation times in precalciner kiln systems and the requirement for high alite cement, the presence of crystal clusters is n...
C2S solid solution reactivity in high-belite cement Premium
The key cause of the high energy intensity in the cement production process is the high heat required to form alite, the main constituent of Portland cement. One option is to lo...
Crystal inclusions in Portland cement clinker Premium
The nature of inclusions in clinker crystals provides clues about the burning environment and are therefore important indicators of clinker quality. Figure 1: blue belite inclus...
How much alite? Premium
The content of alite and other cement phases such as belite, aluminate and ferrite can have significant effects on the strength of the final mortar. This article looks at the co...
Alite size Premium
The practical implications following microscopic examination discussed in the April 2013 issue of ICR showed that the interpretation of alite size is not a simple matter. We tak...
A is for alite Premium
The characteristics of clinker minerals when viewed under the microscope reveal key information about the cement production process. Arthur Harrisson explains their importance, ...
