Based on the agreement with a customer, it is possible to produce grained limestone of different graining than those mentioned in the cited standard.
The moisture of grained limestone cannot exceed 1% on the day of dispatch from the supplier.
It is necessary to agree on other special requirements between the customer and the supplier. These can be bulk weight of grained limestone, ph of water extract, whiteness, determination of hydrophility ratio or increase of retention on 0,55 mm sieve to 1,5% of type No. 8 including the way of control.
