1) concrete impervious grade number
混凝土抗渗标号
2) Impermeable concrete
抗渗混凝土
1.
Waterproof and impermeable abilities are very important to keep the normal state of an engineering project, and the key method to increase impermeability is to use impermeable concrete.
地下工程的防水抗渗能力对于保证工程项目的正常使用至关重要,使用抗渗混凝土是提高抗渗能力的关键。
3) anti-seepage concrete
抗渗混凝土
1.
New workmanships, new materials and new technologies were applied in the construction to ensure the project quality, including anti-seepage concrete, suspended scaffolding, platform formwork, multi-point jacking and accumulated sliding at high altitude, unit glass curtain wall with vertical rib, PRC light compound partition board, siphon collecting system of roof rainwater and etc.
施工中采用抗渗混凝土、倒挂脚手架、台车模板、多点顶推高空累积滑移、单元式立肋玻璃幕墙、PRC轻质复合隔墙板、虹吸式屋面雨水回收利用系统等新工艺、新材料、新技术,保证了工程质量,满足了使用要求。
5) concrete mark
混凝土标号
1.
The concrete mark beased on 90d or 180d age of concrete is more appropriate for concrete dams than the concrete strength class based on 28d age of concrete.
《混凝土重力坝设计规范》DL5108-1999[1]放弃过去长期采用的基于90d龄期的混凝土标号R,改用基于28d龄期的混凝土强度等级C,由于水坝施工期长达数年,这一改变是不合适的。
2.
The concrete mark is the compressive strengthof 15 cm cubic specimens at 90 d age of concrete with 80% rate of security and the strength class is the compressive strength at 28 d age of concrete with 95% rate of security.
我国水坝工程过去一直采用混凝土标号,1997年《水工混凝土结构设计规范》提出改用混凝土强度等级,目前已经出版和正在编制的坝工设计规范,有的继续采用混凝土标号,有的已改用强度等级,颇为混乱。
6) concrete grade
混凝土标号
1.
In view of the different regulations from the new and old standards for the shear torsion checking of the box section of the curved girder bridge, the article tests and verifies the sectional shear torsion of box girder of the curved girder bridge by many methods of increasing the girder height and girder thickness, and enhancing the concrete grade.
该文针对新旧规范对曲线梁桥箱形截面剪扭验算的不同规定,通过增加梁高、梁厚和提高混凝土标号等多种方法验证曲线梁桥的箱梁截面剪扭。
