is an alternative to the method of predicting microsilica concrete compressive strength. SLONSKI [6] determined the compressive strength of high-strength concrete (HSC) using the artificial neural...] calculated the compressive strength of high-strength concrete using the fuzzy logic and the support vector machines (SVM) model. They used the adaptive neuro-fuzzy method and support vector machines......
performance of high-strength concrete (HSC), which could be used as cover of reinforcement of segment, was investigate by three-point load bending tests. Also, the flexural fatigue equations of high-strength concrete with and without polypropylene fiber were established through test analysis. The experimental results indicate that the addition of polypropylene fiber can improve the static bending......
