Furthermore, the mix ratio of concrete and the size of coarse aggregation have also effect on the results of test, but it seems that the effect of the fine coarse aggregation is not evident.

此外，混凝土的配合比与粗集料对测试结果也有重要影响，而细集料的影响似乎并不明显。

It shows that the modified overall calculation method is more scientific and rational and exact on mix ratio design of self-compacting concrete.

结果表明：改进的全计算法是一种科学、合理、准确的自密实混凝土配合比设计方法。

The mix design of strong concrete should follow the principles of low water-cement ratio, low sand ratio and high bone-glue ratio, thus the relatively satisfying effect can be achieved.

高强度混凝土的配合比设计应该遵循低水灰比、低砂率、高骨胶比的原则，这样才能达到比较理想的效果。
