摘要
由于再生骨料存在密度低、吸水率大、压碎指标大、坚固性差、离散性大等不足,且再生粗骨料与其表面附着砂浆间存在薄弱界面区,影响了再生粗骨料混凝土的性能、限制了其工程应用。对再生骨料进行强化处理可改善再生粗骨料的性能,满足各项技术要求,成功应用于实体工程。
Due to the shortcomings of recycled aggregate,such as low density,high water absorption,large crushing index,poor firmness and large dispersion,with the weak interface between recycled coarse aggregate and mortar attached to the surface,which affected the performance of recycled coarse aggregate concrete and limited its engineering application.Strengthening treatment of recycled aggregate can improve its performance,make it meet the technical requirements and be successfully applied in solid engineering.
