2020-6-4 Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...

Belite (dicalcium silicate, Ca 2 SiO 4) forms 15–45% of a clinker, and displays a rounded habit with crystal sizes ranging from 5 to 40 μm.Normally the β polymorph is found in clinkers, although smaller amounts of, α, α ′ H, and α ′ l polymorphs may occur with minor oxides comprising up to 5%. Light microscopy of lamellar structures on etched specimens and X-ray powder diffraction ...
CEMENT CLINKER CHARACTERIZATION BY SCANNING ELECTRON MICROSCOPY. Scanning electron microscopy technology combines the advantages of the more widely used optical microscopy and X-ray fluorescence techniques with chemical and image analysis capabilities.
First cement is a binary system with 30% replacement of clinker by Fly Ash (Portland pozzolana cement, PPC) and the second cement is a ternary system with 50% clinker replacement by limestone and calcined clay (LC 3). The results of blended cements are compared with that of Ordinary Portland cement
2020-5-23 Cement microscopy has been around since LeChatelier first analyzed a portland cement clinker using a microscope in . Building materials The mineral stock of clinkers is often determined in last time by the calculation by the chemical analysis through that the thin pulps of clinkers under the microscope are counted.

5.1 This test method provides a relatively simple and reliable microscopical means of measuring the phase abundance of portland cement clinker (Note 1).Microscopical point counting provides a direct measure of the clinker phase composition in contrast to the calculated Bogue phase composition (Note 2).
Thin sections of Portland cement clinker have been prepared by ion-beam thinning and examined in the electron microscope. The three most abundant phases, alite, belite and tricalcium aluminate have been identified. Features of interest include unexplained reflections in the diffraction patterns from alite and internally twinned or faulted martensite plates in belite.
The scanning electron microscope (SEM) is becoming increasingly recognized as an important instrument for the study of portland cement clinker, cement, and concrete. Images of clinker surface topography are used to study particle size and shape, as well as fracture surface features.
