Aggregates 8-16
Limestone lump graded 8-16 mm
Limestone lumps of 8-16 mm are produced by quarrying followed by crushing and sorting to the required fraction.
Area Of Use
Limestone chippings 8-16 mm are mainly used in the production of concrete mixes. It is also suitable for use in road construction as a base course for road and civil engineering projects.
