Özet
For this study; different colored pyroclastics belong to Kavak ignimbrite that widely spreads around Nevşehir were choosen. These rocks were widely used as building stone in low storeyed buildings and especially in historical building in the past. Nowadays, they have an increasing usage in outer surface covering of the buildings, stairs, floorings, banisters, pools and their surroundings, arches, columns, fireplaces, balcony decorations and restoration applications because of having decorative properties. Sampling was carried out in 6 different areas in the field because they have different color and texture characteristics that change frequently in close areas. At first petrographical and chemical properties of these samples were determined and then standard rock mechanic experiments were carried out in order to determine their geomechanical properties. According to the results, it is exposed that investigated pyroclastics are non-welded ignimbrite and there are important relationships between their geological, chemical, petrographical properties and geomechanical properties. Especially, the samples having opaque minerals, fine grained rock fragments and higher matrix ratio than grain ratio, have lower porosity and higher density and compressive strength.
