砂與粘土界面
英文
sand-clay interface-
The bond effect of various bond material is also researched by use of the test of pored - drilled drawing bond between new and old concretes. this paper also makes a contrast with the effect of mortars " bond, which offers a meaningful reference on how to choose bond materials and to appraise the bond effect
並通過新老混凝土鉆芯拉拔粘結試驗，研究了不同界面粘結材料的新老混凝土粘結效果，並與其砂漿粘結試驗結果進行了對比，對實際工程應用中正確選用界面粘結材料及評價粘結效果具有一定的指導意義。The result of macro - quality experiments show : mineral admixtures markedly slow the hydrating velocity of cement slurry, decrease and delay the hydrating max - temperature, in which steel slag is more effective ; expansive agents compensate concrete shrinkage, enhance the concrete dense degree, strengthen the interfacial layer between fiber and cement matrix and improve the physical mechanics qualities of acic ; minimal admixtures markedly improve the concrete workability property, increase the concrete later intensity & density and the capability of anti - chemical attack and anti - permeability ; hybrid fiber reinforces the toughness of obviously acic by the means of anti - cracking effect of fiber with different sizes and different properties in the corresponding construction levels
實驗結果顯示：鋼渣摻合料能顯著減緩水泥漿體水化速率，降低砂漿的水化溫升並延遲最高溫升時間；補償混凝土收縮，提高混凝土密實度，加強纖維與水泥石的界面粘結，增強混凝土力學性能，但不能明顯改善混凝土韌性。混雜纖維通過纖維的不同尺度與不同性質在相應的結構層次上產生阻裂效應，增韌鋼渣防滲抗裂混凝土；增加混凝土的破壞極限能，極大提高混凝土抗彎曲能力和韌性指數，改善混凝土脆性。Durability ' s of the material such as permeability, heat - resistance, carbonation and steel bar - protection were tested. the bonding characters between anchoring material matrix and post - embedding steel bar, the matrix and the concrete structures were studied
在植筋錨固長度足夠的條件下，混凝土與錨固砂漿的界面粘結強度大小直接決定了植筋錨固的控制荷載，粘結界面成為受力的薄弱環節。
