摘要： 为解决砖混再生粗集料(brick-concrete recycled coarse aggregate, BCRCA)性能不足问题,采用自主研发的负压强化设备研究强化工艺参数。基于X射线衍射分析技术分析钛石膏-矿渣(titanium gypsum-slag slurry, T-S)浆体的强化作用机理,提出灌入饱和度评价指标。将强化后BCRCA用于水泥稳定碎石中,研究其强度变化规律。试验结果发现:选择负压压力为-75 kPa、负压温度为70 ℃、负压时间为14 min作为负压强化最优工艺参数;经过T-S浆体负压强化后,BCRCA的压碎值和吸水率分别降低到27.3%和6.8%,与水泥浆浸泡的BCRCA相比,压碎值和吸水率分别降低了6.83%和23.59%,表观密度从2.615 g/cm3提高至2.678 g/cm3,开口孔隙的灌入饱和度从22.5%提升至35.1%;将强化骨料用于水泥稳定碎石时,无侧限抗压强度和劈裂强度较浸泡强化时提高了40.7%、22.9%。负压强化方式下T-S浆体可以有效强化砖混再生粗集料。
