The use of high performance concretes (high strength and high durability) is becoming more and more common. At the same time there is a tendency towards concrete mixtures which need only minor compaction energy for optimal filling of the formwork. These concretes have a high slump and must therefore be very stable in order to assure homogeneity (see figure 2).

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.
