本发明公开了种再生骨料的改性方法及改性再生骨料混凝土，改性方法包括以下步骤：将再生骨料放入质量浓度5-8%的磷酸溶液浸泡15-24h,用水清洗再生骨料2-4遍，然后取与再生骨料重量比为0.2-0.6%的十二氟庚基丙基笼型倍半硅氧烷，用有机溶剂将十二氟庚基丙基笼型倍半硅氧烷溶解，得到十二氟庚基丙基笼型倍半硅氧烷溶液，然后用十二氟庚基丙基笼型倍半硅氧烷溶液充分湿润再生骨料，晾干后密封保存，即可得到改性再生骨料。本发明改性方法的特点是改性效果好，成本低，环保。经过本发明方法处理过的再生骨料制备的改性再生骨料混凝土，与现有再生骨料混凝土相比，抗压强度、劈拉强度、抗渗性能、抗碳化性能及抗冻性能均有显著提高。
