| 摘 要： | 高抛免振捣混凝土是在自密实混凝土基础上发展起来的依靠从高处抛落产生的动能实现流动密实,并不离析、泌水的高性能混凝土。为使高抛免振捣混凝土技术得到广泛应用,并为规程应用提供数据支持,该文就高抛免振捣混凝土几个方面的问题进行了研究。

Discussion on Several Problems in Technical Specification for Application of High-dropping Non-vibration Concrete |
| |
| Abstract: | High-dropping non-vibration concrete is developed on the basis of self-compacting concrete, relying on kinetic energy obtained by dropping, and it is a kind of high performance concrete with the property of self-leveling and compaction and without separation of the aggregate and bleeding. This paper studies on some problems of high-dropping non-vibration concrete to make it widely applied in constructions and it also to provides data support for relative standards and criterions. |

| Keywords: | dropping height non-vibration performance index testing coarse and fine aggregate SVB slump cone method |
