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 compressivestrengths of concrete with different concrete classes and different slump values. An experimentalstudy based on repetitive vibration application was performed in the laboratory environment andprediction models were developed on the basis of fuzzy logic with reference to this experimentalstudy. In the experimental study, the concretes which are in C20 and C35 and have K3, K5settlement values were produced and determined compressive strengths of the concretes whichhides 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 concreteswhich once-vibrated. The concrete pressure endurance of the vibration time and its repeatedapplications are predicted by the graphical representation of fuzzy logic methods. The compressivestrength values obtained from the prediction models and the compressive strength values of theexperimental data were compared and evaluated. As a result, it is seen that the prediction of theconcrete pressure endurance with the fuzzy model is possible and the fuzzy model is predictedmore accurately to the concrete pressure endurance.
