粘度溫度指數
英文
viscosity-temperature index-
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。Compared with the experiment data, the temperature field and the thermal stress field are discussed. the spacing, the time of sealing and the plane form of the later joint - filled slots are discussed especially, and it is found that the spacing, the time of sealing and the plane form of the later joint - filled slots are comprehensive indexes which are relevant to material, design and construction. the theory value of the spacing and the time sealing of the later joint - filled slots and some proposals on the plane form are presented on the basis of numerical calculation
本文在綜合前輩的研究成果的基礎上，推導了粘彈性場的三維有限元解，對比實際工程實驗數據，對大體積混凝土結構內部的溫度場和應力場進行了分項研究，重點討論了后澆帶的留置間距、封閉時間和平面形狀，發現其留置間距、封閉時間和平面形狀都是綜合指標，是和材料、設計、施工有關的。
