EXPERIMENTAL RESEARCH ON STABILIZATION OF RED CLAY WITH CEMENT AND FLYASH
-
摘要: 单纯用水泥加固某些红黏土地基会存在一些问题,因此考虑采用水泥外加粉煤灰加固红黏土。通过室内试验,测试了具有不同水泥及粉煤灰掺入比、不同龄期的红黏土试块的抗压强度,分析并探讨了水泥和粉煤灰加固红黏土的机理。研究结果表明,固化土试块强度随水泥、粉煤灰掺入比的增大、龄期的延长而提高,并且粉煤灰和水泥对试块早期、中期和后期强度的影响是不同的。Abstract: There are some questions of stabilizing some red clay foundations with only cement.The method of utilizing cement and additional flyash is considered to stabilize red clay.Through the laboratory experiment compressive strength of red clay sample with different mixing ratio of cement and flyash is tested at different ages,and the reinforced mechanism of cement and flyash on red clay is analyzed and probed.The results show that the strength of stabilized soil is increased with the increase of cement and flyash mixing ratio and curing age.Furthermore,cement and flyash affect the sample strength differently at early,middle and later curing ages.
