新混凝土 meaning in Chinese
as placed concrete
Examples
- That new concrete building is an abomination
那座新混凝土建筑是个讨厌的东西。 - The test results show that , the fracture properties of adherence of new and old concrete are evidence lower than the new concrete itself
试验结果表明，新老混凝土粘结断裂性能明显低于新混凝土整体试件的断裂性能。 - The design strength of the new concrete is c40 , which adopts 525 # common portland cement , the sand is middle wide river - sand , the radius of coarse aggregate is 10 - 30mm . the surfaces of the old concrete which are harnessed are divided into i , ii , iii three type faces
Znfl ， ao新混凝土设计强度等级选用c40 ，采用525 ’普通硅酸盐水泥，砂是中粗河砂，粗骨料的粒径为川30mm 。老混凝土表面处理后的表面分为1型面、 11型面、 ill型面三种类型。 - 6 with the optimization of the mix proportion of hprrc and with the old concrete was repaired with hprrc whose strength is close with that of the old concrete , the stress - strain curves of new - old concrete is tested on ordinary testing machine and mts . the results show that under equal stress conditions , the ratios of the strain of old concrete , hprrc to new - old concrete are 82 . 4 - 105 % on ordinary testing machine and 90 - 121 . 3 % on mts respectively
6 、通过优化hprrc的配比，用与老混凝土强度接近的新混凝土对老混凝土进行修补后，在普通试验机和mts试验机上对新老混凝土的本构关系进行了试验研究，结果表明：在等应力条件下老砼、 hprrc博士学位论文.中文摘要的应变与新一老硷的相比，应变的比率在普通试验机上为82 . 4一105 % ，在川、 s上为90一121 . 3 % ，即三者变形是基本接近的。 - ( 2 ) interfacial agents this experiment adopts three types of interfacial agents : no interfacial agent , neat cement paste which has the same water - cement ratio with the new concrete , cement paste mixed with 10 % expanding agent which has the same ratio with the new concrete ( which is called cement paste mixed with expanding agent for short ) . the thickness of the interfacial agent is 2 ~ 3mm
（ 2 ）粘结剂本试验采用三种粘结剂：无粘结剂、同新混凝土相同水灰比的水泥净浆、掺10 u型膨胀剂的同新混凝土相同水灰比的水泥净浆（以下简称水泥膨浆） 。界面剂的厚度一般为2 3mm 。
