Yapý Malzemesi Olarak Denizli Civarýnda Çýkartýlan Kayraktaþlarýnýn Özellikleri

Denizli ili çevresinde iþletilen doðaltaþ ocaklarýnda, farklý yapýtaþlarý çýkarýlmaktadýr. Bunlardan en yaygýn olanlar, traverten, kireçtaþý ve kayrak taþý (þist) ocaklarýdýr. Denizli ilinin kuzey doðusunda, Çal, Bekilli ve Baklan üçgeninde, Mendere masifinin bir üyesi olan kayraktaþlarý bölgenin önemli doðaltaþ kaynaklarýndandýr. Bu çalýþmanýn amacý, bölgede iþletilen kayrak taþlarýnýn yapýtaþý olarak kullanýlabilirliklerinin araþtýrýlmasýdýr. Amacý gerçekleþtirmek için, bölgede bulunan taþ ocaklarý ve sahalarda jeolojik çalýþmalar yapýlarak, kayaçlarýn özelliklerini temsil eden örnekler alýnmýþtýr. Kayaç örneklerinde, petrografik, mineralojik (XRD), kimyasal (XRF) analizler ve jeomekanik deneyler (tek eksenli sýkýþma dayanýmý, Schmidt sertlik deðeri, aðýrlýkca su emme, etkili gözeneklilik, doluluk oraný, eðilme dayanýmý, sonik hýzý, elastisite modülü, doðal ve doygun birim hacim aðýrlýk) yapýlarak elde edilen bulgular kayaçlarýn yapýtaþý olabilirlikleri açýsýndan deðerlendirilmiþtir. Kayaçlarda yapýlan deney ve analizler, uluslararasý doðal taþ standard ve metotlarýna uygun olarak gerçekleþtirilmiþtir. Sonuç olarak, iþletilen kayrak taþlarý özelikleri itibariyle, binalarýn iç ve dýþ cephelerinde, açýk mekanlarda ve çevre düzenlemelerinde yapýtaþý ve kaplama malzemesi olarak kullanýlabilirler.

Properties of Schist Extracted in the City of Denizli Surroundings as Construction Material

There are various type of building stone extracted at stone quarries in the city of Denizli surroundings. Travertine, limestone and schist quarries are the most common in the area. Schist that is one of the units of Menderes massive is the main natural stone sources in Çal, Bekilli and Baklan Triangle in the northeast of the City. The aim of this study is to investigate the usability of schist stone as building stone quarried in the area. To obtain the aim, geological investigations were conducted in the field and representative samples were collected from the quarries. On the samples, petrograpical, mineralogical (XRD), chemical (XRF) analysis and geomechanical test (i.e., uniaxial compressive strength, Schmidt hardness, water absorption by weight, effective porosity, fullness ratio, flexural strength, sonic wave velocity, modulus of elasticity, natural and saturated unit weight) were conducted and the usability of schist stone as building stone have been studied by evaluating obtained findings. Analysis and relevant tests were conducted in accordance with international standards and procedures. Concluding remark is that quarried schist stone in the area are acceptably good as building stone to be used for both interior and exterior of construction building and outdoors as coverage material.
