Abstract：
The nano SiO2, nano CaCO3, steel fiber and concrete were analyzed, through the Losberg bond test of the pull test. The effects of steel fiber volume ratio, nano SiO2 content, nano CaCO3 content and nano materials on the bond properties were discussed. The research shows that the bond strength can be improved by increasing the matrix concrete strength, the optimum value of steel fiber volume ratio is 1.5%, the best content of nano SiO2 is 0.5%~1%, and the best content of nano CaCO3 is 2%.
