自密实混凝土与钢筋的粘结锚固性能试验研究

Bond properties between reinforcement and self-compacting concrete

由于自密实混凝土在材料配合比及施工方法存在的差异,其硬化后与钢筋的粘结锚固性能成为人们关心的问题.本文对不同强度、不同粉煤灰掺量、不同外加剂组合的自密实混凝土与变形钢筋的粘结锚固性能进行了系列研究,并与同等强度普通混凝土进行比较.通过试验,明确了自密实混凝土与钢筋的粘结锚固性能,为工程设计提供依据.

The differences between self-compacting concrete and normal concrete are notable. To ensure the safety of reinforced self-compacting concrete structures in the engineering application, bond behaviors of self-compacting concrete was carried out in this paper. The testing results supply reference to enginering designs of self-compacting concrete structures.
