Bu çalışmada, Portland kompoze çimento ile içerisine metakaolin (%5-10-15-20) ikame edilerek toplam beş farklı çimento elde edilmiş ve metakaolinin, priz başlama ve priz sonu sürelerine etkisi araştırılmıştır. Elde edilen sonuçlara göre tüm karışım oranlarında priz başlama ve priz sonu sürelerinin kısaldığı belirlenmiştir. Ayrıca metakaolinin ikame miktarına bağlı olarak deneysel çalışmaların dışında bulanık mantıkla tahmin edilebilmesi için bir model oluşturulmuştur. Oluşturulan bu modelle elde edilen korelasyon katsayısının priz başlama süresi için 0.9851, priz sonu süresi için 0.9693 olduğu tespit edilmiştir. Sonuçlar, geliştirilen bu modelin çimento ve beton endüstrisinde başarılı bir şekilde uygulanabileceğini göstermiştir.

Prediction the Effects of Metakaolin on the Setting Time of Portland Composite Cement with Fuzzy Logic

Öz

In this study, a total of five different cements were obtained by substituting Portland composite cement with metakaolin (5-10-15-20%) and the affects of metakaolin on the initial and final setting times were investigated. According to the results, it was determined that the initial and final setting times were shortened in all mixing ratios. In addition, a model was created to predict metakaolin with fuzzy logic outside of experimental studies, depending on the amount of substitution. The correlation coefficient obtained with this model was determined to be 0.9851 for the initial setting time and 0.9693 for the final setting time. The results showed that this developed model can be applied successfully in the cement and concrete industry.
