The　cement　composite　calcium　lignosulfonate　is　used　to　enhance　the　mechanical　properties　and　the　freeze-thaw　resistance　of　loess.　Based　on　an　unconfined　compressive　test　under　different　freeze-thaw　cycles,　the　influence　of　cement　dosage,　curing　age,　and　freeze-thaw　cycles　on　compressive　strength　are　discussed.　The　results　indicate　that　the　strength　of　loess　can　increase　by　up　to　13　times,　and　the　loss　of　strength　is　reduced　from　72%　to　28%　under　the　reinforcement　of　cement　dosage　and　curing　age.　The　loss　of　strength　is　mainly　concentrated　in　the　initial　5　freeze-thaw　cycles,　and　the　structure　gradually　stabilizes　after　10　freeze-thaw　cycles.　In　addition,　according　to　the　X-ray　diffraction　test,　it　is　found　that　the　stabilized　loess　exhibits　a　comparatively　more　stable　mineral　composition.　The　scanning　electron　microscope　results　reveal　that　hydration　products　enveloped　the　soil　particles,　forming　a　mesh　structure　that　strengthens　the　connection　between　the　soil　particles.　The　freeze-thaw　damage　makes　the　small　and　medium　pores　turn　into　large　pores　in　loess,　while　the　stabilized　loess　changes　micro　and　small　pores　into　small　and　medium　pores,　with　no　large　pores　found.　It　is　feasible　to　improve　loess　with　the　cement　composite　calcium　lignosulfonate,　which　can　provide　references　for　the　reinforcement　treatment　of　loess.
