- Abstract
Through splitting tensile strength test on the cubic specimens of mill-cut steel fiber reinforced concrete(SFRC), effects of influencing factors including the fiber volume fraction (φi), the maximum coarse aggregate size(dmax) and the water-cement ratio (mw/mc) upon the splitting tensile strength of millcut SFRC(fft) were studied. The results show that steel fibers are able to improve the splitting tensile strength of concrete when the average length of steel fiber is 35 mm. fft and its increment ratio tend to increase as φf or dmax(≤ 20 mm) increases. However fft and its increment ratio tend to decrease as mw/mc increases. fft is related to the characteristics of the cross section of the specimen. Based on the experimental results, a computational model is proposed to calculate the splitting tensile strength of mill-cut SFRC. The splitting tensile strength of mill-cut SFRC is then predicted by means of BP neural network.
