Özet:

 The use of mineral additives in cement production supports an environmentally friendly production process by reducing the amount of clinker and significantly reducing CO2 emissions. Methacholine, obtained as a result of calcination of kaolin at high temperatures, is used effectively as a pozzolan. The study was carried out in two stages to determine the effect of calcination temperature and fineness on the pozzolanic activity index. In the first stage, kaolin was calcined at 3 different temperatures: 600C, 750C and 900C. Mortar samples in accordance with the standard were prepared to determine the pozzolanic activity strength index depending on the calcination temperature. When the 28-day pozzolanic activity strength index results were examined, it was seen that kaolin calcined at 600C provided the best strength value of 122. In the second part of the study, the material calcined at 600 C was ground to three different finenesses as 13800 cm2g, 15900 cm2g and 18700 cm2g, and mortar samples were prepared to determine the pozzolanic activity strength index. As the fineness increased, the pozzolanic activity strength index values also increased.

 Mineral katkıların çimento üretiminde kullanılması klinker miktarını azaltırken CO2 emisyonlarını önemli ölçüde azaltarak çevre dostu bir üretim sürecini desteklemektedir. Kaolinin yüksek sıcaklıklarda kalsinasyonu sonucu elde edilen metakolin, puzolan olarak etkili bir şekilde kullanılmaktadır. Çalışma kalsinasyon sıcaklığının ve inceliğin puzolanik aktivite indeksine etkisini belirlemek amacıyla 2 aşamada gerçekleştirilmiştir. İlk aşamada kaolin 600C, 750C ve 900C olmak üzere 3 farklı sıcaklıkta kalsine edilmiştir. Kalsinasyon sıcaklığına bağlı olarak puzolanik aktivite dayanım indeksini belirlemek için standarda uygun harç numuneleri hazırlanmıştır. 28 günlük puzolanik aktivite dayanım indeksi sonuçları incelendiğinde 122 ile en iyi dayanım değerini 600Cde kalsine edilen kaolinin sağladığı görülmüştür. Çalışmanın ikinci kısmında 600 C de kalsine edilen malzeme 13800 cm2g, 15900 cm2g ve 18700 cm2g olmak üzere 3 farklı incelikte öğütülmüş ve puzolanik aktivite dayanım indeksinin tespiti için harç numuneleri hazırlanmıştır. İnceliğin artmasıyla birlikte puzolanik aktivite dayanım indeksi değerlerin de artış görülmüştür.
