級配良好土
英文
well-graded soil-
The results of research on the workability of hbc concrete show that hbc concrete, when compared with opc concrete, has excellent compatibility with superplasticizer, in terms of better initial fluidity, less slump loss, definite saturation point and less dosage at saturation point. in addition, good mineral admixture such as i class fly ash can obviously improve the workability of hbc concrete. moreover, hbc concrete exhibits more excellent workability under the condition of low w / c ratio, which indicates hbc is more suitable for making super high strength concrete whose w / c ratio is very low
對高貝利特水泥高性能混凝土工作性能的研究結果表明,高貝利特水泥與高效減水劑具有良好的適應性,表現為初始流動度較大,經時損失較小,具有明顯的飽和點且飽和點摻量較小;此外,優質的礦物摻和料如一級粉煤灰能明顯改善hbc混凝土的工作性能;更為突出的是hbc混凝土在低水膠比的情況下表現出更為優異的工作性,這一特性預示著高貝利特水泥更適宜配製水膠比很低的超高強混凝土。It ' s also a better kind of permeation proof materials
寬級配礫質土是一種良好的防滲材料。The long period cyclic tests of four specimens near to sufficient dimension made by the master cao yunfeng prove that the reinforcement arrangement scheme can obtain favorable displacement ductility and plastic energy dissipation capacity for the coupling beams with the small aspect ratio of 1. 0. to go deep into the research further, this thesis concentrates on the two aspects following : ( 1 ) the author of this thesis carries out the long period cyclic test of five specimens near to sufficient dimension to further verify : 1 ) the probability that the upper limit of shear - resistant ability increases to vu = 0. 2fcbh0 or higher
0的位移延性,且耗能能力良好:在跨高比為0 . 8一1 . 25的范圍內,連梁都依然保持上述良好性能;配筋比例應以對角斜筋為主,一組「 l 」形斜筋用量與單向對角斜筋用量的比值宜控制在0 . 35一0 . 55的范圍內;通過對曹雲峰的試驗與本文試驗的綜合分析,表明cz于c45的混凝土強度等級都是可用的,未發現混凝土強度在這一范圍內偏高或偏低時可能帶來什麼不利影響。Well - graded soil
級配良好土Through experimental research, we have pmepared a kind of asphalt - concrete with good technical parameters
