Rock materials for construction In Sweden, we use about 85 million tonnes of aggregates every year for roads, railways and concrete. SGU compiles annual statistics on the quantity of aggregates supplied from Sweden's licensed quarries.


A rock mass is a material quite different from other structural materials used in civil engineering. It is heterogeneous and quite often discontinuous, but is one of the materials in the earth's crust, which is most used in man's construction. Ideally, a rock mass is composed of a system of rock blocks and
