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...
Magnesia in clinker Premium
Magnesia is often present in clinker as periclase, which is formed of free MgO. However, periclase does not always provide a welcome part of the clinker’s composition and can le...
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...
Construction and demolition waste as clinker raw material Premium
The concept of the circular economy encourages the reuse of waste products as raw materials in the production of cement. Arthur Harrisson looks at the use of construction and de...
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...
Alternative clinkers Premium
The drive to lower the carbon footprint of cement has led to the development of alternative cement clinkers to replace Portland cement clinker. Arthur Harrisson examines the pot...
Aluminium and iron in clinker Premium
Aluminium and iron are two of the key components in Portland cement clinker. Varying their presence in clinker can have significant effects on the final clinker. Arthur Harrisso...
