Cement kiln - Wikipedia

If the reaction is incomplete excessive amounts of free calcium oxide remain in the clinker. Regular measurement of the free CaO content is used as a means of tracking the clinker quality. As a parameter in kiln control free CaO data is somewhat ineffective because even with fast automated sampling and analysis the data when it arrives may be 10 minutes "out of date" and more immediate data must be used for minute-to-minute control.

M-CZ composites from Egyptian magnesite as a clinker to RCK ...

Calcium zirconate (CZ) increased from M1 (12.86 wt%) to M2 (25.12 wt%) as zirconia increased then decreased as the available free calcium oxide decreased from M3 to M5. The appearance of merwinite (C 3 MS 2 ) and disappearance of tricalcium silicates (C 3 S) in the XRD patterns in Fig. 3 confirms lower value of calcium/silica ratio (C/S < 2).

Calculation of the C 3 A Percentage in High Sulfur Clinker

The lime reacts with the silicate oxide (SiO 2) to form two calcium silicates phases the dicalcium silicate (Belite C 2 S or Ca 2 SiO 4) and tricalcium silicate (Alite C 3 S or Ca 3 SiO 5). Based on the above approach Bogue proposed four formulae for the calculation of the clinker phase concentrations.

Portland cement clinker: the Bogue calculation

Combined CaO = (66.6% - 1.0% free lime) = 65.6%. This is the figure we use for CaO in the calculation. From the analysis we have: CaO=65.6%; SiO 2 =21.5%; Al 2 O 3 =5.2% and Fe 2 O 3 =2.8%. The Bogue calculation is therefore: C 3 S = 4.0710CaO-7.6024SiO 2 -1.4297Fe 2 O 3 -6.7187Al 2 O 3.
