  • Effect Of P2O5 And Chloride on Clinkering Reaction

    Sep 23, 20050.5 wt% ~ 2.0 wt% of P 2 O 5 and Cl were added to the composite sample using a P 2 O 5 and NH 4 Cl and sintered at 1450C for 20 min to form a clinker mineral. The level of the free lime was determined by the ethylene glycol extraction method. Results of free lime and Cl content of the clinker samples with varying P 2 O 5 and Cl contents are summarized in Fig ure 1.

  • Cement Types, Composition, Uses and Advantages of

    Apr 04, 2018We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.

  • Morphological Analysis of White Cement Clinker Minerals

    The paper deals with a formation of artificial rock (clinker). Temperature plays the capital role in the manufacturing process. So, it is useful to analyze a poor clinker to identify the different phases and defects associated with their crystallization. X-ray fluorescence spectroscopy was used to determine the clinker#x2019;s chemical composition. The amounts of the mineralogical phases are
