The conclusions are as follows : ( 1 ) the compose of rpc has an effect on the bond behavior between cfrp bars and rpc : the bond strength between cfrp bars and rpc will increase with the decrease of water to cement ratio, but doesn ’ t obviously ; the adding of steel fiber can improve the bond behavior between cfrp bars and rpc significantly, but steel fiber will also effect the workability of rpc, consider the bond behavior and economy, the content of steel fiber should be 2 % ;. silica fume can improve the bond strength between cfrp bar and rpc, but the bond strength isn ’ t in proportion to the content of silica fume, in this experiment, the optimal content of silica fume is 0. 25 to 0. 35
試驗研究得到如下結果: （ 1 ） rpc的材料組成對rpc與cfrp筋粘結強度的影響: cfrp筋與活性粉末混凝土的粘結強度隨著水膠比的降低而提高，但是提高的幅度並不明顯;鋼纖維的摻入，可以顯著提高cfrp筋與rpc的粘結強度，但是鋼纖維的增強效果與摻量並不是線性增加的關系，從綜合經濟性及粘結強度兩方面考慮，鋼纖維的最佳摻量為2 % ;摻入硅灰有利於改善粘結性能，但其摻量有一最佳范圍，在本次試驗中，硅灰的最佳摻量為0 . 25 0 . 35 。 -
Since the existed research has n ' t illuminated the failure form of post - embedded reinforcing steel bar bonding anchor and its mechanism, has n ' t systematic research on factors influencing the function of post - embedded reinforcing steel bar bonding anchor, and also failed to test on the long period validity of post - embedded reinforcing steel bar bonding anchor, it is very unfavorable for the spread and application of post - embedding technique. in the meantime, the fact that the present post - embedding anchoring material is of few kinds, high prices and still - to - be - improved performance has become the bottleneck of the post - embedding technique ' s development, which has restricted its further application and development. therefore, it is of great importance to develop a new type high - performance inorganic anchoring material with reasonable price and improved performance
由於已有研究對后植鋼筋粘結錨固的失效形式、破壞機理未作出明確回答，對后植鋼筋粘結錨固性能的影響因素未進行系統研究，對后植鋼筋粘結錨固的長期有效性未予以試驗證實，不利於植筋技術這種新型結構加固技術的推廣應用，同時現有植筋錨固材料存在品種少、價格高、性能需要進一步改進和提高等局限性，已成為植筋技術發展的瓶頸，制約了植筋技術的進一步應用和發展，因此開發價格合理、性能優良的新型高性能無機質類錨固材料就顯得尤為重要和迫切。
