    摘要：通过在混凝土中单掺钢渣和双掺钢渣与纳米SiO2进行试验，研究其掺量与粘结应力的关系，结果表明，双掺钢渣和纳米SiO2对其粘结应力影响较为明显；当钢渣掺量为20%时粘结应力最高；粘结应力与抗拉强度呈正相关性；粘结应力随抗拉强度的变化呈线性发展；粘结应力值和普通混凝土一样，也可根据抗压强度和抗拉强度进行推导。

    Abstract：By single in the concrete with steel slag and double mixing steel slag with nano SiO2 experiment，study the relationship between the bond stress and the content. Result showed that：Double mixing steel slag and nano SiO2 had evident effects on the bond stress. When steel slag content is 20% bond stress is highest. The bond stress and tensile strength was a positive correlation. Bond stress showed a linear development along with the change of the intensity. Same as the normal concrete，the bond stress value can also be derived according to the compressive strength and tensile strength.
