Aggregates 0-8
Limestone lump unsorted 0-8 mm
Unsorted lump limestone 0-8 mm is produced by quarrying and subsequent crushing and sorting to the required fraction.
Area Of Use
Due to its high purity, 0-8 mm limestone is particularly suitable for the metallurgical and chemical industries, ecology (neutralisation of acidic components), construction (preparation of asphalt mixtures) or road construction for compacting road base layers.
