Correlation of Compressive Strength and Other Engineering Properties of High-Performance Steel Fiber–Reinforced Concrete

In this paper, correlations among the compressive, flexural, and splitting tensile strengths of high-performance steel fiber-reinforced concrete (HPSFRC) were analyzed. For the investigation, a large amount of data was collected from the published papers with water/binder ratio in the range of 0.25-0.48, steel fiber volume fraction of 0.5-2.0% with aspect ratio of 40-80, and specimens of 150 mm Ø cylinders and 100×100×500  mm size prisms. Results on the evaluation of the published empirical relations using the collected data indicate a large variation and inapplicability to steel fiber reinforced concrete, which necessitates the determination of empirical relations between the mechanical properties of SFRC. Through a statistical analysis on the data collected, power relations for flexural and splitting tensile strengths as a function of compressive strength, and the relation between flexural and splitting tensile strengths of HPSFRC with r = 0.94, were obtained. The validity of the proposed models was examined with the experimental data of the present study and earlier researcher, and the integral absolute error obtained is 5.1.
