ABSTRACT: Sıcak Çermik, Sankaya and Uyuz Çermik travertine deposits around Sivas are among the most importanttravertine deposits in Turkey. Travertine deposits consist of nearly pure caleite, and. show stratifonn and veintype depositional styles, Banded and spongy structure and micritic texturtfis dominated within the stratifonn typetravertines, while albatr structure and sparitic texture is dominant within the vein type travertine occurences .In this study; industrial characteristics such as; block size, color and ornament sliding, polishing., mohs-hardness, slake durability index, schmidt hardness, transparancy, unit volume mass; specific mass, compactness ratio,water suction relative to mass and volume, porosity, abrasion, uniaxial compressive strength, uniaxial compress ive strength lifter the frost, bending strength, blowing strength,, durability lo the frost, frost lost durability toatmospheric influences, resistance to rusting and acids were investigated and evaluated.The results of these investigations and évaluations show that all these characteristics ofihe travertines inthese deposits range in the Iimites what should be in travertines and they are well qualified materials, suitable touse as facing stone
