The Thermal and Mechanical Properties of the Building Stones in Eskisehir - Kayseri and Kırsehir regions

Abstract

In this study, certain physical properties of Derbent (Eskisehir), Tomarza (Kayseri) and Mucur (Kırsehir) stones, which are used as building materials in the relevant regions, are subjected to analysis. For each stone, the samples were taken from two separate quarries, after which the chemical analysis, thermal conductivity, compression stress, water absorption, breathability and abrasion tests were carried out. The results obtained from the tests carried out are as follows: i) It is understood that Eskisehir Derbent tuff and Tomarza stones can be used as briquettes, bricks or aggregates as lightweight concrete thanks to their low thermal conductivity values (0.355 W/mK and 0.581 W/mK) and heat insulation properties. ii) Kırşehir Mucur stone shows that it can be used in load bearing wall material and abrasion resistant flooring with 88.46 MPa compressive strength and 0.4% volume abrasion values. iii) It has also been conferred that three stones have rich reserves and low costs. The results are compared with other building materials, especially in terms of energy saving, strength and comfort conditions.
