試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。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。There are two different constitution forms for the square tubes with ribs in the test specimens, one consists of two welded channels with stiffening lips ( channel tubes ), stiffening lips ( angle tubes )

混凝土鋼筋的工序尺寸選定彎曲和切削.規范The results show that the compressive strength, splitting tensile strength and flexural strength increase respectively with the addition of steel fibers, but the compressive strength increases little compared with the splitting tensile strength and flexural strength ; for the same kind of steel fiber reinforced concrete, the compressive strength, splitting tensile strength and flexural strength of steel fiber reinforced regenerated concrete are higher than those of steel fiber reinforced pebble concrete ; the load - bearing capacity of blended steel fiber reinforced concrete is less than that of single dimension steel fiber reinforced concrete ; the use of steel fiber reinforced regenerated concrete whose aggregate is made of regenerated concrete can not only turn waste into treasure, but also reduce environmental pollution and realize the recycle of resources, and its load - bearing capacity is far higher than that of steel
結果顯示:由於鋼纖維的加入，混凝土的抗壓強度、劈裂強度和彎曲強度都有不同程度的提高，但抗壓強度不及劈裂強度和彎曲強度提高顯著;對于同種鋼纖維混凝土，鋼纖維再生混凝土的抗壓強度、劈裂強度和彎曲強度比鋼纖維卵石混凝土的相應強度大;混雜尺寸鋼纖維混凝土的承載能力不如單一尺寸鋼纖維混凝土的承載能力;以再生混凝土作為基體的鋼纖維再生混凝土不僅可以「變廢為寶」 ，減少環境污染，實現資源的重復利用，而且其承載能力比鋼纖維卵石混凝土高很多。 3 .總結出鋼纖維混凝土抗拉強度和彎拉強度關系的計算公式。Based on experimental research and theoretical analysis, investigations on the new type of joint are made systematically, the main contents and results include the following items. 1 four specimens of new joints between cfrt columns and steel beams are designed. by low - cyclic reversed load test, skeleton curves of new joints and shearing deformation in joint core area are studied, the influence of parameters, such as concrete cores, length of stiffener, and relative dimensions of column and beam, is discussed
