...混凝土(self-compacting concrete,简称SCC),又称自流平混凝土(self-leveling con-crete)或免振捣混凝土(vibration free concrete),是一种浇筑时不需要振捣,仅通过自重即能充满配筋密集的模板,并且保持良好均匀性的混凝土。

Free vibration method is employed to measure the damping ratio. A great deal of fundamental data for the damping ratio of rubber powder concrete in small deformation is obtained.
采用自由振动法测试得到了一批橡胶混凝土小变形阻尼比的基础性数据。
For every vibrating point, the vibration shall go on till free mortar appears on the concrete surface and not sinks any more, normally 20 ~ 30s.
每一振点的振捣延续时间应使混凝土表面呈现浮浆和不再沉落为止，约20 ~ 30s。
A 5 tonne block of concrete sits in the ground, detached from the rest of the building, to make some LABS vibration-free.
5公吨的混凝土块坐落于地面，与建筑的其余部分分离，使得一些实验室免震。
