Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 C 1500 C The nodules are ground up to a fine powder to produce cement with a small amount of gypsum added to control the setting properties SR NO PARAMETER UNIT RANGE TEST METHOD TEST RESULT A Chemical Parameters 1 Silicon Dioxide SiO 2000 2160 ASTM C1142012 2 Aluminium Oxide AlO 500 640 ASTM C1142012 3 Ferric Oxide FeO 340 450 ASTM C1142012 4 Calcium Oxide CaO 6500 ASTM C1142012 5 Magnesium Oxide MgO 190 ASTM C1142012 6 Sulphur Trioxide SO 155 ASTM C1142012 7 Total Alkali Na2O 065K20 080 ASTM C1142012 8 Chloride Cl 003 ASTM C1142012 9 Loss On Ignition LOI 050 ASTM C1142012 10 Free CaO 180 ASTM C1142012 11 Insoluble Residue IR 050 ASTM C1142012 B Chemical Modules 1 Lime Saturation Factor LSF 9300 Bogue Formula 2 Silica Modulus SM 250 Bogue Formula 3 Alumina Modulus AM 170 Bogue Formula 4 Tri Calcium Silicate CS 55 Bogue Formula 5 Di Calcium Silicate CS 1000 2000 Bogue Formula 6 Tri Calcium Aluminate CA 700 Bogue Formula 7 Tetra Calcium Alumino Ferrite CAF 1000 1400 Bogue Formula Formula for arriving C3S is 4071x CaO Free CaO 760 x SiO2 6718 x Al2O3 143 x Fe2O3
Clinker consists of various calcium silicates including alite and belite. Tricalcium aluminate and calcium aluminoferrite are other common components. These components are often generated in situ by heating various clays and limestone. Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature. The products of the chemical reaction aggregate together at their sintering temperature, about 1,450 C (2,640 F). Aluminum oxide and iron oxide are present only as a flux to reduce the sintering temperature and contribute little to the cement strength. For special cements, such as low heat (LH) and sulfate resistant (SR) types, it is necessary to limit the amount of tricalcium aluminate formed. The major raw material for the clinker-making is usually limestone mixed with a second material containing clay as source of alumino-silicate. Normally, an impure limestone which contains clay or silicon dioxide (SiO2) is used. The calcium carbonate (CaCO3) content of these limestones can be as low as 80%. Second raw materials (materials in the rawmix other than limestone) depend on the purity of the limestone. Some of the second raw materials used are: clay, shale, sand, iron ore, bauxite, fly ash and slag. The clinker surface and its reactions in different electrolytic solutions are investigated by scanning electron microscope and atomic force microscopy. Portland cement clinker is ground to a fine powder and used as the binder in many cement products. A little gypsum is sometimes added. It may also be combined with other active ingredients or chemical admixtures to produce other types of cement including: ground granulated blast furnace slag cement.
