setting shrinkage
解釋
凝固收縮-
Comparing with the same category overseas jointless bridges, the new type bridge has more reasonable structure, more simple and convenient construction, and better use effect etc. the main work in this paper is described as follows : ( 1 ) this paper introduces phylogeny and reseach survey of the joints bridge inland and abroad, and a new jointless bridge structure ? new type semi - integral abutment bridge is based on these, which characteristic of own structure and setting of primary component are expatiated. ( 2 ) this paper analyses influence of temperature effect, creep, shrinkage and circumambient soil of run - on slab on the new type structure, and analyses the forcing performance of beam, abutment and run - on slab of the new type semi - integral abutment bridge, and constrast to the same category joints bridges
本文主要做了以下工作: （ 1 ）介紹了無縫橋梁在國內外的發展歷史、研究概況，並在此基礎上提出了一種新的無縫橋梁結構形式-新型半整體式無縫橋梁，闡述了它特有的結構形式以及主要構件的設置; （ 2 ）分析了溫度效應、徐變和收縮以及搭板周圍土體對這種新型結構的影響，對新型半整體式無縫橋主梁、橋臺以及搭板進行了受力性能分析，並和同類無縫橋梁進行了對比分析。 -
By means of comparative experiments, this paper illustrates the influences of different cements, admixtures of flash - setting agents, water cement ratios, curing temperatures and raw materials on the performances of sprayed concrete, such as the setting time, strength and shrinkage ratio, on different conditions of efflorescence and hydration, so as to present references with regularity for the practical application of sprayed concrete
摘要通過對比試驗，闡明了不同水泥、不同速凝劑摻量、水灰比、養護溫度以及原材料在不同風化和水化程度條件下，對噴射混凝土凝結時間、強度、收縮率等性能的影響，以期為噴射混凝土的實際應用提供規律性的參考資料。 -
For the walls poured by ordinary concrete, the emm and ttm obtain the same qualitative conclusion, despite of some discrepancies in the specific value. but for the walls poured by the scc, the restraining stress calculated by the emm is remarkably smaller than that by the ttm. in other words, the emm results shows that the shrinkage compensation technology can take place the measures of setting dilatation joints, while the ttm results indicates that, though the restraining stress is decreased, the decreased amplitude is inadequate
對計算結果的比較和分析表明，對普通混凝土墻，結果的具體數值有差異，但反映的定性規律相同；對補償收縮混凝土墻，結果差異巨大，等效模量法認為補償收縮技術可實現無縫設計，而時程方法在承認補償收縮技術可減小約束應力的同時，認為應力減幅還不足以實現無縫設計。 -
It can retard the setting time of the concrete. it also can be sprayed on the concrete members, and have good shrinkage reducing rate effect. it can be a kind of conserving agent
水泥對聚丙烯酸鹽類減縮劑的平均吸附率為5 %左右，聚丙烯酸鹽類減縮劑能降低水的表面張力，能使水的表面張力從75 . 7mn / m下降到43 . 5mn / m 。 -
By optimizing and controlling the technology conditions of grey yam linear density, spinning speed, stretching temperature, stretching ratio, tension - setting and shrink - setting, the polyester staple with shrinkage rate over 20 % was successfully developed with normal polyester chip
通過對原絲線密度、紡絲速度、拉伸溫度、拉伸倍率、緊張熱定型及鬆弛熱定型等工藝條件的優化和控制，採用常規聚酯切片成功開發出收縮率在20 %以上的滌綸短纖維。
