Abstract
Marble exposed to temperature cycles at high relative humidity (RH) under laboratory conditions loose strength similar to loss of strength for the same marble exposed to natural climate. Two marble types from three different building facades in Copenhagen are studied. From each building a marble cladding panel exposed for the south facing natural climate during 29, 60 and 61 years, respectively, and a cladding panel of each of the marble types only exposed for indoor climate are cut in bars of size 30x30x300 mm. The bars from indoor are exposed to temperature cycles between 10 °C and 60 °C at nearly 100% RH and at nearly 0% RH. The strength of the natural exposed marble as well as the laboratory-exposed marble are measured as flexural strength under concentrated load using four-point loading. Analysis of the strength test show that it is possible to transfer test results for laboratory exposed marble to results for natural exposed marble.
