Broken stones and rubble stones made of limestone are used as decorative stones, in retaining walls, and in water and landscape construction. In this ...

Limestone is primarily composed of calcium carbonate (or calcite). It is a sedimentary rock. Over millions of years, deposits from ancient seas have s...

A portion of the lump lime is further processed into white fine lime. For this, the material is pre-crushed in a impact mill to grain sizes below 20 m...

Limestone, which is not suitable for the production of quicklime due to its relatively low calcium carbonate content, is processed into various limest...

Washed limestone sand 0-4 mm wet and limestone sand 0-2 mm dry are used for plastering, artificial stone products, stairs, window sills, and fountain ...

Limestone flour is produced by grinding limestone in a roller bowl mill. nekafill® 15 is used as a limestone filler for concrete and asphalt. nekafor®...

Similar to KFN Netstaler® 0-15 mm, Bergschotter 0-30 mm is also used for special natural surfaces. Bergschotter is used in road and civil engineering ...

A product certified according to the standard SN 670119-NA is made from natural and locally sourced materials, primarily used in engineering and road ...

KFN gravel sand 0-63 mm is a good base material for load-bearing subgrade. In general, this gravel sand is well-suited as an unbound mixture.

The unwashed KFN drainage gravel 30-50 mm is used as drainage gravel, filter gravel, and for gravel terraces. Railway connection tracks are also laid ...

When limestone is heated, quicklime (calcium oxide) is produced in the form of lump lime: CaCO3 + heat => CaO + CO2 The reaction occurs at approximate...

Calcium oxide reacts with water, generating significant heat, to form calcium hydroxide. CaO + H2O => Ca(OH)2 + heat One kilogram of calcium oxide thu...

For use in steel production, grain sizes of 5-15 mm are primarily required (nekafer® 15). The transport of lump lime is mostly done in bulk by rail.

KFN Netstaler® 0-15 mm is a very pure limestone gravel. Due to its high calcium carbonate content, this gravel is fundamentally suitable for lime burn...
