The evaluation on the effect of effective and repetitive vibration to compressive strength with the fuzzy method

Abstract

In this study, it was aimed to develop alternative prediction models for estimating the compressive strengths of concrete with different concrete classes and different slump values. An experimental study based on repetitive vibration application was performed in the laboratory environment and prediction models were developed on the basis of fuzzy logic with reference to this experimental study. In the experimental study, the concretes which are in C20 and C35 and have K3, K5 settlement values were produced and determined compressive strengths of the concretes which hides in suitable conditions after 30 minutes, 60 minutes and 90 minutes, 7 and 28 days, respectively. Other results are evaluated with considering the 28 day concrete strength of concretes which once-vibrated. The concrete pressure endurance of the vibration time and its repeated applications are predicted by the graphical representation of fuzzy logic methods. The compressive strength values obtained from the prediction models and the compressive strength values of the experimental data were compared and evaluated. As a result, it is seen that the prediction of the concrete pressure endurance with the fuzzy model is possible and the fuzzy model is predicted more accurately to the concrete pressure endurance.
