混凝土塌落度 的英文怎麼說
中文拼音 [húnníngtǔtālàdù]
混凝土塌落度
英文
slump constant of concrete-
L & t is required to control the quality of supplied concrete to ensure the qualified slump and workability of concrete during casting
要求l & t注意控制混凝土的質量，保證供到施工現場的混凝土塌落度及和易性。The result of experiment states hpc which initial slump is more than 230mm, after 120min is still above 190mm ; the 7d and 28d hydration, the compression strength of concrete is more than vompa and 90mpa can be made from the ground high - ti bfs instead of 10 - 30 percent of equal p. o. 525r, with the aid of superplasticizer and additive on the water cement ratio is 0. 26
利用磨細的高鈦礦渣等量取代10 - 30的硅酸鹽水泥，並摻入高效減水劑b和外加劑ua ，在水灰比為0 . 26時，可以配置出初始塌落度大於230mm ， 120min后，塌落度仍大於190mm ， 7天強度大於70mpa ， 28天強度大於80mpa的高性能混凝土。The study on the control of slump of commercial concrete
商品混凝土塌落度控制的研究Method of test for slump of concrete
混凝土塌落度的試驗方法In this paper, the confecting technique on many ingredients " hpc was studied, and the optimum ratio of many ingredients in hpc was confirmed by regression method in spss and optimizing method in matlib, considering mechanics performance of high performance concrete and collapsing slump of hpc mixture. c : bf : fa : sf : uea = 3 : 1 : 1 : 0. 2 : 0. 02. we confected out hpc with the ratio
用這一比例關系我們配製出塌落度達130mm 、早期強度高、後期強度增長幅度大的高性能混凝土，其7d 、 28d和56d的抗壓強度分別為47 . 55mpa 、 71 . 05mpa和88 . 8mpa ，後期強度增長率可達到25 。When 20 percent cement is replaced by finely ground ti bfs in equal quantity, the hpc which initial flow ability can be improved greatly and its loss has been down. after 120min, the slump is 190mm, the spreading is 415mm, and the issue time is 15 seconds, which is absolutely applied to the pumping concrete
摻入20高鈦礦渣微粉，採用1 . 2的高效減水劑b可以得到塌落度、擴展度較大且損失較小的高性能混凝土， 120分鐘時，塌落度為190mm 、擴展度為415mm ，流出時間為15s ，符合泵送混凝土的要求。分享友人
