Prediction of Flexural Strength of Portland–Composite Cement Mortars Substituting Metakaolin Using Fuzzy Logic

Abstract

In this study, Fuzzy Logic models have been introduced to predict flexural strength values of cement mortars. For this purpose, reference cement mortar containing only Portland–composite cement, and mixtures having metakaolin replacing 5, 10, 15 and 20% by weight of the Portland–composite cement were produced. The mortars’ flexural strength values were established at 2, 7, 28 and 56-day with standard cement test. In addition, Fuzzy Logic prediction models were created by using fuzzy triangular number coefficients and Gauss membership function to predict flexural strength of cement mortars. Subsequently, experimental with fuzzy results are compared. Accordingly, the correlation coefficient of flexural strength of cement mortars for fuzzy triangular number coefficients and Gauss membership function were found 0.84 and 0.87, respectively. These results show that between experimental and fuzzy results are a good harmony, and can be successfully applied in civil engineering applications.

Metakaolin İkameli Portland Kompoze Çimento Harçlarının Eğilme Dayanımının Bulanık Mantık Yaklaşımıyla Tahmin Edilmesi

Abstract

Bu çalışmada, çimento harçlarının eğilme dayanım değerlerini tahmin etmek için Bulanık Mantık tahmin modelleri geliştirilmiştir. Bu amaçla, referans ve %5, 10, 15 ve 20 oranında metakaolin ikameli çimento harçaları üretilmiştir. Üretilen bu harçların eğilme dayanım değerleri 2, 7, 28 ve 56. günlerde standart çimento deneyleri ile tespit edilmiştir. Ayrıca, çimento harçlarının eğilme dayanımlarını tahmin etmek için üçgen bulanık sayı katsayıları ve Gauss üyelik fonksiyonu kullanılarak, Bulanık Mantık tahmin modelleri oluşturulmuştur. Deneysel sonuçlar Bulanık Mantık sonuçlarıyla karşılaştırılmıştır. Sonuç olarak, bulanık üçgen sayı katsayıları ve Gauss üyelik fonksiyonu için çimento harçlarının eğilme mukavemeti korelasyon katsayıları sırasıyla 0,84 ve 0,87 olarak bulunmuştur. Bu sonuçlar, test sonuçları ile bulanık sonuçlar arasında iyi bir uyum olduğunu ve inşaat mühendisliği uygulamalarında başarıyla uygulanabileceğini göstermektedir.
