On lab research of free-vibration and self-compaction concrete and its practice

The paper indicates the technique demand of the free-vibration and self-compaction concrete,introduces the production research on the free-vibration and self-compaction concrete from the material selection,the checking indexes,and the optimized proportional ratio,and points out the application of the concrete can save resources and energy whiling reducing noise pollution,so it can be further applied in urban reconstruction.
