Özet:

In this paper, the mixture design parameters for the mixture design of concretes with and without mineral additive (silica fume) were determined by compiling 3760 concrete data for 470 concrete series with the decision tree algorithm. Comments and analyzes were made on the results obtained. When the results of the decision tree algorithm were examined, the most effective parameters on the concrete mixtures were determined. Obtained results show that the most important parameter for each compressive strength range is cement dosage and other parameters come later depending on their importance. On the other hand, if high compressive strengths are desired, the fine matter content should be chosen close to the specified values, and it can be said that the gap-filling effect of the fine aggregate and the resultant compact concrete formation/high compressive strength relationship are shown. In addition, the result of the analysis obtained provides a solution with 75% accuracy to choose which mixture content and which amounts for different strength ranges. Thus, the suggestion that which concrete content can be selected for which strength, regardless of the details in the relevant standards developed for concrete mix design (for example, TS 802), is supported by the literature data.
