Clay is a term used to describe a group of phyllosilicates. The “pure” clay is rare in nature and usually mixed not only with other clays but with microscopic crystals of carbonates, feldspars, micas and quartz. In the sedimentary term, it is typically less than 2 μm in diameter. Plasticity, sintering and absorption of water form the important characteristics of the clay minerals. Clays constitute the majority of the presence mineral that occur as the alteration product of building Stones. The carbonate rocks using in various historical constructions are mainly composed of calcite. Dolomite, silica and clay minerals of alteration product accompany with this mineral. Mineralogical studies show that the clay minerals in traditional building stones are the feldspar type of clay mineral which occur as an alteration product of feldspar. The feldspar is found small amount in the structure of these stones. The presence of clay in the carbonate rocks such as marl and limestones causes to the various decomposition in the building stones. For this reason, it is not recommended the presence of clay minerals in the carbonate rocks. In this study, the clay minerals in the structure of the carbonate rocks using in the traditional structure restoration in the Edirne region have been described and the effects of clay minerals on the spoiling of the building stones has been discussed. For this purpose, the clay type and their characteristics that cause the decrease of life of the buildings are first examineted and than visual front spoil have been discussed. In the regional scale, the common usage of the carbonate stones containing clay such as marl in the building stones increases the front spoil indensity in visual.
