Research on the influential factors of SFNMRC bond strength
GUAN Xiaojun
Abstract：Using Losberg experiment and center binding test to analyze the influence of substrate concrete strength,nano SiO2 mortar and steel fiber volume rate on the bond strength of steel fiber concrete,and the curve of bond stress-slip is received. The results show that the bond strength of SFNMRC improves with the increase of concrete strength and steel fiber volume ratio;Nano SiO2 content between 0.5%~1.0% has obvious effect in increasing the initial strength and ultimate strength of steel fiber concrete.
