Abstract

It was tested the physical and mechanical properties of recycled coarse aggregate under the different gradation,and designed three kind recycled concrete specimens of different maximum particle sizes,and the concluded by analyzing data: Recycled coarse aggregate,regardless of the continuous gradation or the single gradation,its apparent density,bulk density were all lower than the natural crushed stone,but the moisture content,the crush indicators and water-absorptivity are greater;but the continuous gradation and the single gradation performances were also different.The recycled concrete workability increases with the water consumption and addition of mixture,but the intensity was reduced.
- gradation,
- recycled coarse aggregate,
- preparation of recycled
