A Model Proposal on Results of Physical and Mechanical Properties of Trakia Region Küfeki Stone Used at Early Period Ottoman Buildings

Abstract

Küfeki, is a building material because of its porous structure, which has low vapor permeability resistance and heat conductivity. The aim of this article is analyses for the features of küfeki stone with physical experiments used frequently in restoration applications nowadays. Here, it was compared with the küfeki stone samples used in historical buildings which approximately was built before 400 years and was taken from stone quarries in Trakia region. The water absorption test by volume under atmosphere pressure experiment was made based on TS 699 standards for analyzing of küfeki stone physical features. As a result of the experiments carried out, it is seen that the samples taken from the quarries absorb less water than the other samples taken from the historical buildings. This shows that the other stones are relatively deformed in time, under load and under various external influences.
