In this study, physicochemical, petrographic and mechanical properties of original lime mortars from a Roman Period basilica in Amasra dated to the 1 st or 2 nd centuries are examined. The study of mortar samples has been performed through polarising and stereo microscope observations, mineralogical (XRD) analyses, chemical (ICP-ES), physical and mechanical analyses. The micro structure and semi-quantitative chemical composition of the binding media and aggregate phases were determined by Scanning Electron Microscope with Energy Dispersive (SEM-EDS) analysis. This mortar possessed its hydraulic characteristic is due to the addition of volcanic rock with pozzolanic nature. Mechanical tests revealed that the average compressive strength of mortars is 6,1 N/mm 2 and flexural strength is about 3,3 N/mm 2 . Pull-off tests for determining the adhesion properties proved that a good adhesion is established between mortar and andesite stone owing to its pozzolanic nature.

Kosova’ nın Prizren ili, Mamuşa ilçesi’nde bulunan saat kulesi, Osmanlı döneminde, 1815 (H.1230) yılında Prizren Mutasarrıfı (Kaymakamı) Mahmut Paşa tarafından yaptırılmıştır. Yapı, bazı özgün olmayan değişikliklere ve statik problemlere karşın, günümüze kadar ayakta kalabilmeyi başarmış ve uzun yıllar hizmet vermiştir. Mamuşa Saat Kulesi’nin çanı, Mahmut Paşa tarafından, savaştan sonra Semendire’deki bir kiliseden alınarak Mamuşa Köyü’ne getirilmiştir. Moloz taştan yapılan dikdörtgen prizma gövdeli saat kulesi kırma çatıyla örtülmüştür. Çatı üzerinden yükselen ve çanı taşıyan bir çıkıntı daha bulunmakta olup, saat kulesinin yüksekliği, 14.40 metredir. Saat Kulesi’nin korunması, sürekliliği için hazırlanmış olan restorasyon projesinin önemi büyüktür. Bu nedenle yapılacak olan restorasyon projesinin, sürekliliğin ve korumanın ikinci en önemli aşaması olacağı rahatlıkla söylenebilir. Makalemizde, saat kulesinin tanımı, projelerinin oluşturulması süreci anlatılmıştır.The clock tower in...

The relationship between ultrasound pulse velocity (UPV) with pozzolanic activity of lime mortars produced with clays calcined at different temperatures were examined. Three different types of clay samples were calcined at 550, 650, 750 and 850 o C. All the calcined clays were ground in proper granulometric sizes and with them, a series of 12 batches of lime mortars were mixed. From three per mix, a total of 36 samples were prepared in accordance with TS 25 standard. Two extra batches of mortars were prepared for comparison purposes; pure lime mortar and a pozzolanic lime mortar mixed with rock powder. All the samples were cured in accordance with ASTM C593-95 standard. There is a close and good relationship between the UPV with pozzolanic activity and mechanical properties of lime mortars produced with clays calcined at different temperatures. Hence, pozzolanic activity can be predicted also by non-destructive methods. Keywords : Lime/Clay Mortar; Calcination; Ultrasound Pulse Velo...
