Belite size distribution Premium
Belite size is affected by several factors ranging from raw materials, the length of the burning zone, the fuels used in the production process as well as the conditions in the ...
Process, mineralogy and cement quality Premium
This month Arthur Harrisson looks at the relationship between temperature differences in the clinker manufacturing process, the composition of clinker produced and the quality o...
Belite-based low-carbon clinker cements Premium
While Portland cement is expected to remain the most-used cement type in concrete production, alternative cements are gaining importance. This has seen the continued development...
Belite in Portland clinker Premium
While belite is often represented as a pure dicalcium silicate, in practice the phase contains a range of impurities. Arthur Harrisson highlights the differences in belite compo...
Belite appearance in clinkers Premium
This month Arthur Harrisson looks at the second-most abundant constituent of cement – belite – and its appearance in clinkers. Figure 1: Type I belite with multiple sets of para...
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...
