Formation of ordinary Portland cement?
Ordinary Portland cement is form from materials of limestone or chalk and clay in proportion of 78and 22% respectively. The limestone and the clay are crushed and water is added to form slurry. The slurry is the heated at a high temperature in a klin to form clinker. The clinker is grinded into a powder and a range of gypsum is added which generate setting or hardening when water is added.
What reason of brown core in clinker?
burning clinker in reducing condition,cooler and longe flame
What is the function of the cement of a tooth?
so your tooth stays in place. If the cement wasn't there your tooth would fall out pretty easily
What is the standard density of clinker?
1400kg/m3
What is the meaning of clinkerisation temperature?
temperature at which clinker nodules are produced with the optimum composition
Do you have a good knowledge about cement clinker crusher?
no
Free lime of Portland cement?
Determination of Free Lime in Clinker and Cement?
How much clinker is used to make one ton of cement?
0,74 tons of clinker (depending on the quality tho)
What is clinker role in cement production?
Clinker is ground (usually with the addition of a little gypsum, that is, calcium sulfate dihydrate) to become Portland cement. It may also be combined with other active ingredients or chemical admixtures to produce:
What is Opc and ppc grade of cement?
OPC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and high reactive silica. High reactive silica improves the quality of cement by reducing liberated lime.
What changes in the Raw meal composition are needed to increase 28 days compressive strength of cement clinker of opc cement at clinker manufacturing stage?
You should increase the LSF (lime saturated factor). Normal the LSF is around 95. If you increase the LSF you will proberly get a worse burnability.
How do you increase secondary air temperature in cement kiln?
Slow down the stroke of the grates of the cooler.. Increase the clinker abundance and pressure in cooler.. So, you can increase the temperature by taking advantage of the hot clinker.
What are the manufacturing steps of cement?
Cement is a powdered mineral, which when added to water reacts to form an element that glues sand, gravel and stones. Its produced by propositioning of different elements that include, calcium oxide, silicon oxide, aluminum oxide and iron oxide, and burning them in a clinker at a temperature about 1450 to form clinker which is then grounded to form cement.

Aim of le chatelier soundness test?
Le- chatelier test is being done to see expansion, caused by cement due to excess free lime in clinker.
