This study was carried out to predict the setting times of silica fume substituted cement pastes using ANFIS. In the first part of the study, the initial and final setting time of cement pastes obtained by substituting silica fume into Portland cement at 0%, 2.5%, 5%, 7.5% and 10% were determined. In the second part, two models with Triangular and Gaussian membership functions were created with the experimental results and the initial and final setting time were predicted. In the third part, R2, MAPE and RMSE statistical methods were utilized to indicate the reliability of the prediction results. As a presentation, R2, MAPE and RMSE values were determined as 0.9882-0.9778, 0.015156-0.018960 and 3.8027-5.8689 for Triangular membership function and 0.9882-0.9778, 0.015226-0.018956 and 3.8006-5.8689 for Gaussian membership function, respectively. According to these results, it can be stated that both initial setting time and final setting time can be predicted "very well" or "with a high degree of accuracy" with the models constructed with Triangle and Gaussian membership functions.
