摘要
根据正交设计选择的配合比制作自密实混凝土振捣与免振捣两组试件,进行同步对比研究。结果表明,在用水量和高效减水剂含量适宜时,振捣对混凝土强度影响较小。
In this study, a new kind of Self-compacting High Performacne Concrete, with no-vibration, was expected to be developed, according to the selected mix ratios, two groups of concrete specimens, one of which was made with no vibration, were made, in order to do parallel studies. The comparing of the ratio of the strength of the group with no vibration to its corresponding group, would help us to see that, whether the reducing effect of no vibration on the compressive strength of cubes and the splittign tensile strength is evident.
