摘要：Self-compacting rock-fill concrete with natural and recycled aggregate can be applied in large structural components'production. According to the deep analysis of material's mechanical properties test data, the author makes a study on the strength mechanism of the concrete material. The results show that the concrete material essentially is concrete, and the concrete strength of large-sized natural aggregate and recycled aggregate are basically the same. However, due to the varieties in material production process and material shape as well as the influence of the mechanical properties and aggregate size, the strength mechanism of them is different. Effective control on mechanical properties of self-compacting rock-fill concrete and aggregate's appearances and shapes is helpful to the strength design of the self-compacting rock-fill concrete with large aggregate.
