New hydraulic additive as a clinker substitute

Nov 13, 2013 · A cost saving arises from the fact that during the production of Portland cement clinker, about 1.65t of raw meal is used to make 1t of clinker. Only about 1.21t of raw meal is needed to make 1t of the new clinker substitute, meaning that about 25 - 27% less raw meal needs to be used.

3.5 Properties of the major cement minerals

The C 3 A in portland cement clinker, which typically contains about 13% oxide substitution, is primarily cubic, with smaller amounts of orthorhombic C 3 A. The C 3 A and C 4 AF minerals form by simultaneous precipitation as the liquid phase formed during the clinkering process cools, and thus they are closely intermixed. This makes it difficult to ascertain the exact compositions of the two phases.

This product is a type of blended cement obtained by grinding portland cement clinker with a little amount of limestone as a mineral additive and a setting regulating agent. It can be used in areas where portland cement is used. As it contains additives, its heat of hydration is lower in comparison with portland cement.

3.4 Burning in a kiln – formation of cement clinker

Cooling zone: As the clinker moves past the bottom of the kiln the temperature drops rapidly and the liquid phase solidifies, forming the other two cement minerals C 3 A (aluminate) and C 4 AF (ferrite). In addition, alkalis (primarily K) and sulfate dissolved in the liquid combine to form K 2 SO 4 and Na 2 SO 4. The nodules formed in the clinkering zone are now hard, and the resulting product is called cement .

These materials are blended together, either wet or dry, and fed into a rotary kiln, which fuses the limestone slurry at temperatures ranging from 2,600 to 3,000°F into a material called cement clinker. After it cools, the clinker is pulverized and blended with a small amount of gypsum to control the setting time of the finished cement.
