This data sheet was compiled by the Building Research Establishment (BRE). Where possible, data collected in earlier surveys has been used to help interpret the test results. The data sheet was compiled in July 1997 using the results of tests carried out to the proposed European Standards. The work was carried out by BRE as part of a Partners in Technology Programme funded by the Department of the Environment and Stancliffe Stone Co Ltd and does not represent an endorsement of the stone by BRE. 

General
The quarry is on the southern outskirts of the village of Stanton-in-Peak off the Birchover Road. The quarry was reopened in 1983 and has good reserves of stone. 

Petrography
Stanton moor is from the Millstone Grit of Carboniferous age. Stone from the quarry is fine-grained to slightly medium grained, buff in colour, some pink stone is also available. The depths of the beds vary from about 1.5m up to 3.6m and the lengths vary from 700mm up to 1.8m. 

Expected Durability and Performance
It is important that the results from the from 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. Sandstones from the Millstone Grit series are traditionally acknowledged as generally being a very durable building and paving stone and have been used extensively in many towns and cities in the UK. Stanton Moor sandstone appears to be a durable stone that is not effected by acid rain or air pollution. The weight lost in the harsh saturated sodium sulphate crystallisation test indicates limited resistance to salt damage in very severe environments (for example in coastal locations or from de-icing salts); the results suggest that the stone would have good frost resistance. The compressive strength of the stone is typical of the range for comparable with sandstone. The flexural strength is towards the lower end of the range for sandstones and if used for paving then the units may need to be thicker than those for some other sandstones. The abrasion resistance is comparable with York paving stones and should be suitable for use in heavily trafficed areas. 

Overall, should be suitable for use in most aspects of construction including flooring, paving, load bearing masonry and cladding.
