Abstract:Stabilized soil has goodcompresive,frostresistant,water-resistant,anddrywetcycleresistance properties,and is widelyused intheconstructionof infrastructuresuchaswaterconservancy,transportation,andports.Toimproveits compressive performance,commonsandysoil,loess,andclayin Hebei Province were selected asresearch objects.Through diferent mixratios ofcompresiveperformance tests,theefects ofcement,naphthalene sulfonic acid formaldehydecondensate, anhydroussodium sulfate,silica,flyash,andsodiumchlorideonthecompresivestrength of the materialswereanalyzed. Furthermore,afunctionalrelationshipbetweenthecompresivestrengthofmodifiedfluidizedbedsolidifiedloessandthe compositionratiowas established.Research hasshown that theadditionof naphthalene sulfonicacid formaldehydecondensate andanhydrous sodium sulfatecanimprove thecompressive strengthofcuredpowders;Whenincreasing thedosageofly ashand silica,thecompresive strengthof thesolidified powderfirst increasesandthenremainsunchanged,while increasingthedosage of sodiumchloridecanleadtoanincreaseandthenadecreaseinthecompressivestrengthof thesolidified powder.Theresearch results can provide reference for the application of solidified soil.
