Aggregates testing equipment Matest

Mineral aggregates are a component of composite materials such as concrete and asphalt used to add strength to the overall composite material. For this reason, International Standards require several and precise tests on their properties. Like aggregates, rocks need special cares too: a rock stratum undergoes several alterations in case of excavations and handlings.
