# Quality Control Formula

## Loss on ignition (LOI) (CO2 from Calcination)

## Silica Modulus/Ratio (SM)

## Alumina Modulus/Alumina iron ratio (AM)

Clinker with higher the Alumina modulus results in cement with high early strength

## Lime saturation factor (LSF)

When the LSF approaches unity, the clinker is hard to burn and often shows the excessive free lime contents.

## % Liquid

## Bogue’s Formula for Cement Constituents

## Degree of Calcination

## Sulphur to Alkali Ratio

Higher sulphur to alkali ratio leads to pre-heater buildups affecting the kiln operation

## Free Lime

Excess sulphur (gm SO3/ 100 kg clinker)

Above these limits, sulphur gives rise to coating problems in Pre-heater tower.

## Blending ratio

## Raw meal to clinker factor

## Kiln feed to clinker factor

## Clinker to cement factor

## Insoluble residue

Insoluble residue can be used to measure amount of adulteration or contamination of cement with sand. Cement is soluble in dilute HClwhere as sand is insoluble. The amount of insoluble material determinesthe level of adulteration. In PPC (Fly-ash) cement; insoluble residue is used to estimate the percentage of fly-ash present in the cement.

sanjuQuite informative.

Syed Ali Abidihi

my name is Ali

I ma working in cement Company as chemist

my question is about factors using in LSF ort C3S formulas

like in C3S formula 4.071CaO -7.60 SiO2 + 6.718 +…………..

From where these facotrs come from ? in detail

Thanks
