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.
