Bu çalışmada, 550, 650, 750 ve 850 Co sıcaklıklarında pişirilmiş kil malzeme ile üretilmiş kireç bağlayıcılı
harçların puzolanik özellikleriyle ultrases hızları arasındaki ilişkiler incelenmektedir. Bu amaçla, yukarıda
belirtilen sıcaklıklar arasında kalsine edilen killer pişirme işlemi sonrası uygun granülometrik boyutlara
getirilerek XRD analizleri yapılmış daha sonra bu malzemelerle ASTM C 593-95 standardına göre kireç
bağlayıcılı harçlar hazırlanmıştır. Yapılan mekanik ve ultrases hızı ölçüm testleri sonucunda, çeşitli
sıcaklıklarda kalsine edilmiş killerle üretilmiş harçların ultrases hızları ile puzolanik ve mekanik özellikleri
arasında anlamlı ilişkilerin bulunduğu tespit edilmiştir. Elde edilen sonuçlar puzolanik aktivitenin
değerlendirilmesinde söz konusu tahribatsız yönteminin yardımcı bir metot olarak uygulanabileceğini
göstermektedir.
