    Abstract: This research presents the application of the Box-Benken design method to develop a model for predicting contour slump flow and its desirability in self-compacting concrete (SCC) with partial replacement of cement with bentonite. The slump flow has been measured for 15 mixtures prepared at the laboratories of Al Hussien Bin Talal University and Ajloun National University. The use of Bentonite as filler materials in self-compacting concrete can add many benefits that are directly related to the workability and consistency of various cementitious materials, besides the fact that it is possible to reduce the quantities of cement and optimize the percentage in the composite. The performance of the model can be judged by the Correlation Coefficient (R2), Mean Absolute Error (MAE) and Root Mean Square Error (MSE) which have been adopted as the comparative measures against the experimental results obtained from the mixtures, and found the best percentage of Mennonite in SCC.
