In the quarry lab, all the necessary test are carried out, according to the requirements for the CE, on a weekly basis for the production materials:
- Grain-metric analysis (EN 933-1) – Testing the geometrical qualities of the aggregated. Definition of the grain metrics. Screener method.
- Grain-metric analysis (EN 933-1) – Testing the geometrical qualities of the aggregated. Definition of the grain metrics. Screener method.
- Methylene blue anhydrous (EN 933-9) – Tests for geometrical properties of aggregates. Quality assessment of fines. Testing of methylene blue anhydrous.
In addition, the following tests are undertaken in an external certified lab, on an annual basis.
- Density of silica flour with a densitometer (ΕΝ 1097-7)
- Bulk density and void measures of aggregates (ΕΝ 1097-3)
- Density and humidity absorption of aggregates (ΕΝ 1097-6)
- Flow coefficient of fine aggregates (ΕΝ 933-6)
- Test of Sulphur Magnesium (ΕΝ 1367-2)
- Density on lightweight additives (ΕΝ 1744-1)
- Chemical attributes of aggregates: Density in humic components (ΕΝ 1744-1)
- Chemical analysis: Total sulphuric, soluble sulpuric in acids, soluble chlorides (ΕΝ 1744-1)
