煤矸石质固土材料固化土的耐久性试验研究

Study on durability experiment of stabilized soil of gangue sialite soil material

  • 摘要: 为评价煤矸石质固土材料固化土的耐久性能,研究了煤矸石质固土材料固化土的耐水性能、耐干湿循环性能、抗冻融性能以及耐酸、碱、盐腐蚀性能,通过与普通硅酸盐水泥固化土的性能对比,对煤矸石质固土材料固化土的耐久性能进行了试验研究。结果表明,煤矸石质固土材料固化土14 d耐水稳定系数为0.94,耐干湿循环交替系数为0.898,抗冻系数为0.9,煤矸石质固土材料固化土在这3项性能上均优于水泥加固土。耐酸碱盐性能方面,煤矸石质固土材料固化土耐酸性略逊于水泥固化土,而耐碱和盐腐蚀性能明显优于水泥固化土。
