混凝土的流动性试验

Through the slump test of steel fiber reinforced concrete mixture, factors which can influence on the fluidity of SFRC such as the quantity of steel fiber volume rate, sand percentage and fly ash quantity were analyzed and the corresponding empirical formula was given.

sand percentage ； fluidity ；通过对钢纤维混凝土拌合物的坍落度试验，分析了在一定条件下，钢纤维掺量、砂率及粉煤灰等因素对大掺量混凝土拌合物流动性的影响，给出了相应的经验公式。

A lot of experimental results and theoretical analysis of the thesis indicate that X FLOUR has at the same time important roles of fluidizing, water reducing, strength increasing, service life lengthening and so on.

论文大量的试验结果与理论分析表明：X粉在混凝土中同时具有流化与减水、增强、延寿等重要作用，用它可以实现混凝土高强高性能，配制高流动性、高强度、高耐久性的&三高&混凝土，以及用于耐化学腐蚀的环境等，可以实现施工工艺的更新，可以获得经济、环保、生态等多种效益。

This solves contradiction about fluidity capability and segregation capability. Through SCC"s tests on flowing property, filling performance, passing ability and segregation are done by adopting slump test tube, V funnel and L fluidity instrument, the results of SCC"s flowing property are gotten under the case whose water gel ratio and coarse aggregate are changed.

通过采用坍落度筒、V漏斗和L型混凝土流动仪实验仪器对不同骨料的自密实混凝土的流动性、混凝土的填充性和钢筋通过性、混凝土的抗离析性等系统试验，得出了在改变水胶比和粗骨料的情况下自密实混凝土流动性能的变化结果。

The experiment results show that the recycled concrete with high fluidity, high durability or high strength can be produced by using low water-bind ratio, employing good quality super-plasticizer; adding of fly ash and colloidal silica and controlling the maximum size of recycled aggregate.

试验表明采取低水胶比、高效减水剂、粉煤灰和硅灰作为掺合料、控制再生骨料的最大粒径，可以制备出高流动性、高耐久性、高抗折强度的高性能路用再生混凝土。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
