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 。Products and systems for the protection and repair of concrete structures - test methods - determination of the adhesion of injection products, with or without thermal cycling - slant shear method
