Collecting Samples
At al levels of the production process, samples are collected
in line with the Quality Plan. Quarries, purchased raw
materials, raw material crushing, raw material grinding,
clinkerization, cement grinding and product shipment points
are sample collection points that represent the main production
processes. After the raw materials are crushed and before
they are fed into the kilns automatic sampling methods
are in effect. At the product shipment points, spot sampling
and product control compliant with EN norms are implemented.
Preparation of Specimens
Samples undergo a preparation process before analysis. These
processes consist of the reduction of the sample to a representative
amount, drying, grinding, etc.
Analyses
and guidance of production
The specimens are held subject to physical and chemical analyses. Analysis
methods are implemented according to the EN standards. Data obtained from these
analyses is used to provide that it is shared by the production workforce and
the management in its most general sense so as to increase the performance
of the production processes and to increase the quality of the end product.
All phases of the analysis methods and the guidance and implementation of the
production processes have been documented; transparency and straightforwardness
is the fundamental factor.
Analyses carried out in the laboratories;
Physical analyses: fineness, specific surface area, grain
size distribution, liter weight, density.
Wet chemical analyses: Aluminum oxide, silicon dioxide,
iron oxide, calcium oxide, alkalis, magnesium oxide, sulfur
trioxide, free lime analyses in cement and raw materials
and also X-ray spectrophotometer tests and all tests that
can be made by wet chemical analyses.
Mortar and concrete tests: ASTM and TS EN concrete durability
tests, initial and final set times, expansion of concrete,
false set, pack set index, autoclave expansion tests are
conducted.
Fuel analyses: Humidity, sulfur, volatile matter, calorimetric
tests; Na2O, K2O determination with Flame Photometer apparatus
and soluble Cr 6+ analysis with chromium determination apparatus.
