    The amount of total silicates in the clinker is controlled by cement chemists via the silica ratio or modulus: Silica Modulus = %SiO2/ (%Al2O3 + %Fe2O3) The higher the silica modulus the more silicates, C3S and C2S, will be present in the clinker at the expense of the aluminate, C3A, and aluminoferrite, C4AF.10 Basic Facts on Clinker Clinker and Cement Clinker,This conclusion was also reached in the Delta-free lime study carried out by LCR: the decrease in setting time through an increase in free lime is most effective when the degree of lime saturation in the raw mix is high. 5 Clinker C3S content Increasing clinker C3S (to the detriment of C2SClinkerization Cement Plant Optimization,Higher the AM, lighter the color 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.

  • What is Cement Clinker? Composition, Types & Uses Civil

    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.how to increase C3S & reduce freelime in clinker Page 1 of 4,Dec 04, 2013· re how to increase C3S & reduce freelime in clinker. Dear All. I am thinking to increase the % of Petcoke to 90% instead of 80% in the fuel mix.

    It imparts resistance to chemical attack. Rising of C2S content renders clinker harder to grind, reduces early strength, decreases resistance to freezing and thawing at early ages and decreases the heat of hydration. The hydrolysis of C2S proceeds slowly. At early ages, less than a month, C 2S has little influence on strength and hardness.Breakthrough Innovation in Producing Green Clinker,Clinker Increase in Clinker Production at Ultratech Cement ltd.
