Abstract

Ashes of the oil shales burned at different temperatures reach optimum pozzolanic activity at around 700 °C and also possess binding properties. Studies performed over the oil shale ash and cements containing 15 % and 30 % ash have been supported by microstructure investigations X-ray diffraction and electron microscope studies and thermal analyses have also indicated that the ash had some pozzolanic activity in addition to its cementitious property and 15 % addition of 700 °C ash would give satisfactory results.

Özet

Farklı sıcaklıklarda yakılan bitümlü şistlerin külleri 700 °C'da optimum puzolonik aktiviteye ulaşmakta, aynı zamanda bağlayıcı özelliğe sahip olmaktadır. Kül ve külün % 15 ile % 30 oranlarında katıldığı çimentolar üzerinde yapılan çalışmalar mikroyapı incelemeleri ile desteklenmiştir. X-ışını difraksiyonu, elektron mikroskop ve termal analiz incelemeleri de külün bağlayıcı özelliğine ilâveten zayıf da olsa puzolanik aktivitesi bulunduğunu, 700 °C lık külün % 15 oranında katılması ile uygun sonuçlar alınabileceğini göstermiştir.
