Aggregates

Mineral aggregates are used in all fields of the construction industry to produce bituminous misture, concrete, mortars to be used in structures, fill materials, railway ballast etc. For this reason we have given particular attention to all testing methods. The EN Standards have grouped all tests on aggregates in five main subjects:

  • Tests for general properties of aggregates

  • Tests for geometrical properties of aggregates

  • Tests for mechanical and physical properties of aggregates

  • Tests for thermal and weathering properties of aggregates

  • Tests for chemical properties of aggregates

In the majority of cases the EN Standards correspond to other reference Standards as for example ASTM and AASHTO and, apart from a few exceptions there is almost no difference in the specification of test apparatus.
