This paper presents an investigation into the bond strength of three common façade stones, namely, travertine, granite, and marble, to a concrete substrate using shear-splitting test. The effects anchorage, number curing days, presence anti-freezing agent in cement–sand mortar on were studied. results show that days had significant impact between stones substrates. accelerator increased bonding...

The purpose of this research was to compare the geotouristic potential Sub-Tatra Region, expressed in values expert assessment geosites, against preferences tourists coming area. Tourist were evaluated by a survey which assessed attractiveness types geosites that can be admired valorizations showed high and very indices for most analyzed geosites. highest these show particularly geotourism thre...

BACKGROUND A profile across 8 layers from a fossil travertine terrace from a low temperature geothermal spring located in Svalbard, Norway has been studied using both Raman spectroscopy and SEM (Scanning Electron Microscopy) techniques to identify minerals and organic life signals. RESULTS Calcite, anatase, quartz, haematite, magnetite and graphite as well as scytonemin, three different carot...
