    Dec 11, 2018 路 Higher silica content of clinker might lead to harder to grind to clinker due to higher C2S content in clinker. It also depends on the lime saturation and combination degree. Low alumina modulus would not be expected to cause dustry clinker. That is more.

    Dec 04, 2013 路 re how to increase C3S & reduce freelime in clinker To increase C3S the options are increase LSF, decrease free lime, increase silica ratio. With 14% residue on 90 microns you probably dont wish to increase the silica ratio so increasing the LSF seems a good idea, but if you cant reduce free lime below 1.5% with less than 93% LSF (after ash is added from fuel) then this may just make things more.

    The C3S that forms in a cement clinker contains about 3-4% of oxides other than CaO and SiO2. Strictly speaking, this mineral should therefore be called alite rather than C3S. However, as discussed in Section 3.2, we will avoid using mineral names in this monograph.

    Higher the AM, lighter the colour of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.

    Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. The basic, egg-cup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker. For nearly half a century, this design, and minor.
