为了解决再生细骨料性能劣化问题,采用饱和石灰水溶液预处理加速碳化法,以不同粒径再生细骨料(recycled fine aggregate,RFA)为研究对象,进行吸水率、压碎值和表观密度测试,并采用热分析(TG)、X射线衍射(XRD)和扫描电子显微镜(SEM)等对...为了解决再生细骨料性能劣化问题,采用饱和石灰水溶液预处理加速碳化法,以不同粒径再生细骨料(recycled fine aggregate,RFA)为研究对象,进行吸水率、压碎值和表观密度测试,并采用热分析(TG)、X射线衍射(XRD)和扫描电子显微镜(SEM)等对碳化产物和微观结构进行测试。结果表明,随着RFA粒径减小,吸水率逐渐变大,压碎值和表观密度变小;加速碳化生成的方解石紧密堆积并填充于RFA内部微裂缝,使其吸水率、压碎值降低,表观密度升高;小粒径RFA具有更高的CO_(2)质量吸收率,RFA粒径越小,吸水率降幅越明显;天然骨料碎屑聚集在0.3~0.6 mm的RFA中,阻碍了CO_(2)的吸收,其吸水率降幅最低。展开更多
