Portland cement clinker: the Bogue calculation

In practice, the above process of allocating the oxides can be reduced to the following equations, in which the oxides represent the weight percentages of the oxides in the clinker: BOGUE CALCULATION. C 3 S = 4.0710CaO-7.6024SiO 2-1.4297Fe 2 O 3-6.7187Al 2 O 3. C 2 S = 8.6024SiO 2 +1.0785Fe 2 O 3 +5.0683Al 2 O 3-3.0710CaO C 3 A = 2.6504Al 2 O 3

Question: How Do You Calculate Clinker Factor? Ceramics

Lime Saturation Factor (LSF) The Lime Saturation Factor is a ratio of CaO to the other three main oxides. Applied to clinker, it is calculated as: LSF=CaO/(2.8SiO2 + 1.2Al2O3 + 0.65Fe2O3) Often, this is referred to as a percentage and therefore multiplied by 100.

Analysis of clinker phases with the ARL 9900 Total Cement

Table 1 shows the results of chemical analysis (total oxide concentration) obtained by the XRF part of the instrument. These concentrations are used to calculate the equivalent concentrations of clinker phases using Bogue formulæ: %C 3 S = (%CaO %CaO free) x 4.07 (%SiO 2 x 7.6 + %Fe 2 O 3 x 1.43 + %Al 2 O 3 x 6.72) %C 2 S = %SiO 2 x 2.87

Developments in the Measurement and Estimation Methods

From this analysis, concentrations for the major oxides are derived. Since mineralogical information is not available from XRF spectra [4], these measured compositions are further used to calculate the hypothetical compositions of clinker phase minerals using the Bogue equations [5]. However, the

This calculation is based on the hypothesis that the main oxides in clinker are four (s,a,f,c) and that they combine in four phases (c3s,c2s,c3a,c4af). (the intitial assumption) If you have a certain mix of the four main oxides (s,a,f,c), you can calculate how much of the four clinker phases you can get from that: (c3s,c2s,c3a,c4af).

Clinkerization Cement Plant Optimization

Raw meal, Hot meal and Clinker Parameters: Lime Saturation Factor (LSF) is the ratio of the actual amount of lime in raw meal/clinker to the theoretical lime required by the major oxides (SiO 2, Al 2 O 3 and Fe 2 O 3) in the raw mix or clinker.

Calculating CO2 process emissions from Cement Production

resulting lime reacts in the kiln with silica, aluminum, and iron oxides present in the raw material to produce clinker. Clinker, an intermediate product, is mixed with a small amount of gypsum and/or anhydrite to make Portland cement. Some varieties of masonry cement require additional lime, and thus may additional CO 2 emissions. CO

Calculation of the C 3 A Percentage in High Sulfur Clinker

Jun 27, 2010· The correlation between the amount of C 3 A (Ca 3 Al 2 O 6) and the total percentages of clinker SO 3 was linear till the clinker SO 3 reached just 2%. Over that the influence of the clinker SO 3 becomes indistinguishable since the standard deviation of the results according to ASTM C1365:06 is 0.47.. The results in Table 1 show that the ratio of the aluminium oxide and SO 3 in the silicate

CO2 produced per kg of clinker Page 1 of 1

Apr 03, 2011· Re: CO2 produced per kg of clinker. When calculating CO2 emissions from raw material chemistry, certain assumptions have to be made. eg you can calculate the CO2 given off by the limestone component if you assume all of the CaO comes from limestone. (some CO2 is also often associated with MgCO3 but let's concentrate on the CaCO3 for now) In

Cement Clinker: the Bogue Calculation • Aggregate Research

Jul 01, 2010· Clinker is made by combining lime and silica and also lime with alumina and iron. If some of the lime remains uncombined, (which it almost certainly will) we need to subtract this from the total lime content before we do the calculation. For this reason, a clinker analysis normally gives a figure for uncombined free lime.

Re: Raw meal to clinker ratio Page 2 of 5

In a kiln which is being fed with raw meal at 350t/h and has a 'raw meal to clinker ratio' of 1.55 (calculated without respect to bypass), the actual amount of clinker produced with say 10t/h bypass dust removal will be;-(350 / 1.55) 10 = 215.8t. Therefore the 'raw meal to clinker factor' ,allowing for removal of this bypass dust, will be;-

Thermodynamics of Clinker Formation

The obvious difference is that, if free lime remains un-reacted until a high temperature, the entire calcium oxide of the clinker will be free before that temperature is reached. On the other hand, in Model 2, although decarbonation begins at a lower temperature, no free lime appears until the calcium carbonate is 70% decomposed, and the final

Cement Kilns: Clinker Thermochemistry

The oxide percentages are those in the loss-free clinker, normalised to 100.00%. If not all oxide values are available, then the calculation can be performed on the reduced set, again normalised, but bear in mind that in a typical clinker, the contributions of Ti, P and Mn lower the value by about 15 kJ/kg.

Clinker: Cement chemistry notation Understanding Cement

Clinker: Cement chemistry notation. Cement chemists use a form of notation which, at first sight and maybe second or third sight may seem a little odd. Oxides are referred to by their first letter: 'C' represents CaO; 'M' is MgO and so on, for all the oxides likely to be encountered in cementitious systems, as shown below.
