Abstract:
The use of pullout strength of steel fiber reinforced concrete (SFRC) to evaluate the shear flexural and compressive strength of SFRC containing a condensed silica fume is discussed. First, the effect of fiber reinforcement and silica fume addition on pullout strength was investigated with different apex angles of the concrete frustrum. Then the correlations between the pullout strength of steel fiber reinforced concrete and shear strengths were obtained for three types of shear test methods. In addition, compressive strength and flexural strength were also correlated with the pullout strength. The test results show the addition of fiber reinforcement and silica fume significantly improves the pullout strength. The regression analysis of the test data shows that a close correlation exists between the shear strengths and the pullout strength of the steel fiber reinforced concrete. The magnitude of pullout strength is found to be approximately the same order as that of indirect shear strength.
