Compiled May 2000
This data sheet was compiled by the Building Research
Establishment (BRE). It is based on data from current tests at BRE (2000). The
data sheet was compiled in May 2000. The work was carried out by BRE as part of
a Partners in Technology Programme funded by the Department of the Environment,
Transport and the Regions and Marshalls

General
Petrography
Scout Moor is a blue green, fine grained sandstone
from the Millstone Grit series of Carboniferous age.
Expected Durability
and Performance
It is important that the results from the individual tests
are not viewed in isolation. They should be considered together and compared to
the performance of the stone in existing buildings and other uses. Sandstone is
traditionally acknowledged as generally being a very durable building and paving
stone and has been used extensively in many towns and cities in the UK. Scout
Moor sandstone appears to be a durable stone that will have limited resistance
to acid rain or air pollution. The negligible weight loss in the sodium sulphate
crystallisation test indicates high resistance to salt damage (for example in
coastal locations or from de-icing salts). From the frost test the stone should
also have good frost resistance. The compressive and flexural strength of the
stone is very high for a sandstone. The high density and compressive strength
indicate that the stone should be suitable for use in heavily trafficked areas.
Overall, Scout Moor should be suitable for use in most aspects of
construction including flooring, paving, load bearing masonry and cladding.
Special consideration is required for areas where a long service life is needed
in acidic environments. The stone is traditionally used for walling and paving.
