Compound Composition of Clinker / Cement Four major compounds formed from the oxides under high temperature in the kiln Name (Oxide Notation) Shorthand Tricalcium silicate (3 2) – C3S Dicalcium silicate (2 2) – C2S Tricalcium aluminate (3 2O 3) – C3A Tetracalcium aluminoferrite (4 2O 3. Fe 2O 3) – C4AF

Sometimes, other mineral additives such as ground limestone, fly ash, or slag, are also added during the final stages of cement manufacture, even for ordinary Portland cement. In fact, most cements in India have fly ash or ground limestone as a minor additive (BIS permits up to 5% performance improver).

In Nigeria, approximately 40 to 50 per cent of cement manufacturing cost is energy related; each tonne of ce ment requires 60 130 kg of fuel oil or its equivalent and about 105 kWh of electricity, depending on the cement variety and process type employed [10].
