Aggregates 0-4
Limestone lump unsorted 0-4 mm
Unsorted lump limestone 0-4 mm is produced by quarrying and subsequent crushing and sorting to the required fraction.
Area Of Use
Due to its high purity, 0-4 mm chunky limestone is particularly suitable for the metallurgical and chemical industries, ecology (for neutralising acidic components), construction (for preparing asphalt mixtures) or road construction (for compacting road base layers).
