tough index
toughness index
toughness number
Examples
- In addition , woven fiber grid can overcome the shortcoming of steel " s easy corrosion and high density . so it is also a new researchful tendency to substitute woven fiber grid for steel in concrete
在混凝土梁中铺设编织纤维格栅后，其抗弯强度与抗弯韧性指数得到大大提高，另外纤维格栅还克服了钢筋易锈蚀和容重大的缺陷。 - The influence factors of brittleness of hslc such as w / b ratio , sand percentage , type of aggregate and binder constitution are analyzed by the experiment : in order to improve the toughness of hslc , we study the function of fiber , polymer , aggregate and low - layer steel fiber on improving toughness , and explain the mechanism of improving toughness of them
最后采用这四种技术复合增韧，得到了和理想结构模型相符的高强高韧性轻集料混凝土，较基准轻集料混凝土抗压强度增加16 . 3 ，抗弯强度增加97 ，冲击韧性提高171 . 9 ；劈裂抗拉强度增加52 . 6 ，韧性指数提高19 . 2倍，并且具有耐久、经济等优良性能。 - 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
实验结果显示：钢渣掺合料能显著减缓水泥浆体水化速率，降低砂浆的水化温升并延迟最高温升时间；补偿混凝土收缩，提高混凝土密实度，加强纤维与水泥石的界面粘结，增强混凝土力学性能，但不能明显改善混凝土韧性。混杂纤维通过纤维的不同尺度与不同性质在相应的结构层次上产生阻裂效应，增韧钢渣防渗抗裂混凝土；增加混凝土的破坏极限能，极大提高混凝土抗弯曲能力和韧性指数，改善混凝土脆性。 - Based on these test results , the effect of the kind of fiber on the reinforcing and toughening state of sfrc is analyzed the experimental results show that the kind of fiber affect the reinforcing and toughness state of sfrc greatly . the experimental results are analyzed using fracture - cmod toughness method , flexural toughness index isjiojao and toughness index design value
在试验的基础上，分析了纤维种类对钢纤维混凝土增强、增韧性能的影响；运用断裂cmod韧度法、 《钢纤维混凝土试验方法标准》 cecs13 : 89推荐的弯曲韧性指数评价方法和美国astmc1018 - 89标准推荐的韧度设计值分析本文中的试验结果。
