The density of cement plays a significant role both in its
production and performance. The raw minerals are heated in
huge ovens to promote chemical changes and this
produces “clinker”. The final steps in cement manufacturing
involve grinding (milling) and blending that produce the
fine powder that is recognizable as cement. Every step in
the manufacture of cement is checked by frequent physical
tests, as is finished product, to ensure that it complies
with all necessary specifications.
The density of cement should be known in connection with
the design and control of concrete mixtures.
Density
Whether needed for the Blaine, or as a value in its own
right, density has historically been determined by liquid
displacement using, for example, kerosene or naptha. It is
necessary to thermostat the liquid to within +/- 0.2oC.
Disposal of used, wet sample is not usually considered in
standard methods and multiple measurements necessarily
incur a great deal of operator effort. Not so with
automatic gas pycnometers. Samples as large as 135 cc bulk
volume can be accommodated (thereby improving sampling
statistics), purged of air automatically, run multiple
times automatically and a printed report generated within
minutes. The sample is recovered unharmed and dry, and the
very same aliquot can be used for a subsequent Blaine
analysis or other test. This method has already been
adopted by a number of cement companies worldwide, and is
standard in applications such as petroleum coke, pitch,
coatings, carbon, cellular plastics, soils, ceramics,
catalysts, etc.
