In addition, the ultimate bond strength decreases with the increase of anchorage length and bar diameter.
此外，极限粘结强度也随着锚固长度、钢筋直径的增大而减小。
Results indicate that the ultimate bond stress between bars and RPC decreases with the increase of bar diameter or with anchorage length when bar diameter is the same.
研究表明：活性粉末混凝土与钢筋的极限粘结应力随着钢筋直径的增加而下降，钢筋直径相同时随着锚固长度的增加而降低。
