different recycled aggregate diameter的用法和样例：
- This article system research concrete mechanics performance in same water-cement ratio situation and different recycled coarse aggregate replacement percentage.
- In an examination recycled aggregate used instead of a normal macadam and sand 1...
- The percentages of recycled aggregate are 0,30%,50%,70% and 100%. The same slump of each concrete was obtained by adjusting the quantity of water.
- Regardless of the age, compressive strength of recycled aggregate precoating is around 11% higher than that of recycled concrete.
- The result indicates pre-wetted aggregate can improve workability and decrease slump loss due to large water absorption of recycled aggregate.
