Study on the Solidification of Clay with Sodium Dodecyl Sulfonate and Polyvinyl Alcohol
The suitability test of the local clay in Lu'an was carried out by using sodium dodecyl sulfonate(SDS)as the ionic activator and polyvinyl alcohol(PVA)as the binder.The mixture of SDS and PVA with mass ratio of 1∶4,1∶2,1∶1,2∶1 and 4∶1 was diluted to 1∶50,1∶100,1∶200 and 1∶300,respectively,and each concentration diluent was solidified and compacted with Lu'an clay.The unconfined compressive strength(UCS)test was conduc-ted on the solidified soil at each age.The test results showed that the UCS value of Lu'an clay first gradually in-creased and then gradually decreased with the increase of curing agent concentration.Finally,the physical and chemical properties of Lu 'an clay solidified by SDS and PVA were studied by electrochemical,colloidal and physi-cochemical reaction mechanism.The results showed that SDS and PVA were suitable for curing local clay in Lu'an and could meet the requirements of local roadbed engineering.
