阿契奇
  1. 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。
  2. The impermeability experiment under the conditions of high hydraulic pressure in long time shows that the impermeability grade of acic is further beyond p40 and that the steel slag series of acic is better than the fly ash ones

    高水壓滲透實驗表明中低標號鋼渣防滲抗裂混凝土抗滲標號高於p40 ,優于同摻量粉煤灰混凝土,滿足深水條件下混凝土的抗滲要求。
  3. The process of structure formation of acic is studied by means of xrd, sem and so on. meanwhile, the cause and mechanism of the acic compensating shrinkage have been analyzed, and the composition, structure and the rule of durability influence of acic have also been proved up

    通過xrd 、 sem等微觀測試手段研究了鋼渣防滲抗裂混凝土的結構形成過程,分析其補償收縮原因及機理,探明了鋼渣防滲抗裂混凝土相組成、結構及其對耐久性的影響規律。
  4. This paper analyses the problem of concrete cracking and leakage, and set up the model of the middle or low - strength steel slag anti - cracking and impermeable concrete ( acic ) on the base of the analysis. the four principles of water permeable resistance character, volume stability character, toughness and anti - chemical corroded character have been put forward for raw materials selection and durability design of acic, acic is designed by the theory of composite material and the theory of fiber - reinforced, and two series of acic, such as fly ash series and steel slag series, have been manufactured by means of mineral admixture, hybrid fiber and chemical admixture. hydrating heat, macro - mechanics quality, durability and microstructure of the acic have been researched

    本文對中低標號大體積混凝土滲透開裂問題進行了研究,從混凝土自身結構形成與經濟角度指出大摻量粉煤灰與膨脹劑復合配製大體積混凝土的問題所在,提出採用鋼渣微細礦粉配製中低標號防滲抗裂混凝土的思路,運用復合材料理論設計中低標號防滲抗裂混凝土,提出了低水化熱、抗滲性能、體積穩定性、韌性和抗沖磨性能是中低標號防滲抗裂混凝土材料選擇和耐久性設計的主要原則,採用鋼渣微細粉復合混雜纖維、化學外加劑的技術路線,配製了適合於深水等特殊環境中的大體積中低標號鋼渣系列防滲抗裂混凝土,對其進行水化特性、宏觀物理力學性能、耐久性和微觀結構研究。
