| Abstract: | Binding properties of big recycled aggregates and self-compacting concrete are analyzed systematically, and the numerical simulation model of binding properties is also discussed. It shows that the low water-cement ratio of SCC effectively improves the cohesive force between big recycled aggregates and self-compacting concrete; binding strength gets higher with the strength of big recycled aggregates higher and the surface rougher. |

| Keywords: | big recycled aggregates self-compacting concrete binding properties |
