Abstract

In this research, the chemical properties and pozzolanic activity of Karamursel-Kaytazdere volcanic tuffs were studied. The main aim of this study is to reproduce traditional lime based mortars with local materials for the restoration of historical buildings. With this goal in mind, first of all pozzolana which can be used in repair mortar was researched and then mortars that have similar properties with original mortar were produced in the laboratory by using this pozzolana material. Together with the physical and mechanical properties of the mortars produced in the laboratory were determined with experimental studies. According to the evaluation of the test results of the physical and mechanical properties of the repair mortars, it was seen that the repair mortar samples were compatible with the original samples. It can be concluded that the pozzolanic activity of the volcanic tuff quarried from Karamursel region was found satisfactory.

Key words: Volcanic tuffs, pozzolana, experimental methods, repair mortars, historical buildings.
