Description
COTTAER SANDSTEIN -gwg- is an extremely fine-grained gray-white to yellow Elbsandstone without the possibility of colour selection. The colour alterations may correspond to the stratifications or be cloudy-nodular, lively and irregular. Its typical marbled structure arises from the stored undulating clay films in the stratum.
Finished architectural elements from this material are used in exteriors as well as interiors.
Special Aptitude:
Façades, including column and pillar coverings, window and door frames, split-faced and column blocks including roofing slabs, interior architectural elements, prominent masonry work in restoration and new buildings.
Geological Formation:
cretacious, early turonian Labiatussandstone
Petrophysical Characteristics:
flexural tensile strength: 5,5 - 5,8 Mpa DIN EN 12 372
Resistance to breaking the anchor with plate thickness of 4 cm: 1.100 - 1.250 N
5 cm: 1.850 - 1.950 N DIN EN 13 364
Rough-hewn density 2.020 kg/m³ DIN EN 1936
total porosity 24% DIN EN 1936
Water absorption 14,2 Vol.-%; 7,1 Mass.-% DIN EN 13 755
Compression stability 42,5 Mpa DIN EN 1926
Frost resistance frost resistant DIN 52 104-A
anti-slip property Schliff C60 = Rutschhemmung R 13 DIN 51 130
