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: 600°C, 750°C and 900°C. 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 600°C 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 cm2/g, 15900 cm2/g and 18700 cm2/g, and mortar samples were prepared to determine the pozzolanic activity strength index. As the fineness increased, the pozzolanic activity strength index values also increased.}, number={2}, publisher={Süleyman Demirel Üniversitesi}
