This paper probes into the influence of compaction effort on gradation based on gyration compaction and sieving analysis test.
通过旋转压实试验和筛分试验，探讨压实功对混合料级配的影响。
Each of these systems has its trade-offs, but generally the compaction phase is an expensive one in terms of time and effort.
每个这样的系统都有自己的平衡方法，但一般说来压缩阶段在时间和工作上都耗费颇多。
The effort spent on careful grading, mixing and compaction of concrete will be largely wasted if the concrete is badly cured .
如果混凝土养护得很差，那么在精心选定混凝土的级配、拌和和密实成型上所耗费的精力将是徒劳无益的。
