Thermal and Mechanical Properties of Building Stones Used in Some provinces in the Marmara Region

Abstract

In this study, some physical properties of Lefke (Bilecik), Keşan (Edirne), Çan (Çanakkale) and Küfeki (Istanbul) stones, which are used as building materials in their regions, were investigated. Samples were taken from two separate quarries for each stone, and after chemical analysis, thermal conductivity, compressive strength, water absorption, respiration ability and abrasion tests were performed. As a result of the tests, it has been revealed that i) Çan, Tüfekî and Lefke stones, among the ones examined, with low thermal conductivity coefficient values (0.342 W/mK, 0.564, 0.860 W/mK), can be used as briquettes, bricks or wall covering materials for thermal insulation and decoration purposes, ii) Keşan stone can be used in load-bearing wall material and wear-resistant flooring with 81.3 MPa compressive stress and 4.83% wear rate values and iii) four stones have rich reserves and low costs. The results were compared with other building materials especially in terms of energy saving, strength and comfort conditions.
