Abstract：With Hanzhong soil as raw material,the natural waste slag powder and natural agricultural wastes sisal fiber resources as modifiers,the modified soil samples were prepared respectively by different modifier types and proportions of activators,and fiexural and compressive experiments of sixteen sets of specimens were contrasted,and the alkali-activated effects of different types of activator improving the strength of raw soil material were studied by experiments.The results showed that the total amount of activated agent should not be too much and 5％ is appropriate,and the previous activated effect of Na2SiO4 was poor,and the late activated effect of Na2,SiO4 improved obviously,and the activated effect is (Na2,SiO3∶NaOH=1∶1)＞(Na2SiO3∶NaOH=1∶2)＞NaOH＞ Na2SiO4＞Na2CO3.Sisal fiber added can improve the flexural strength significantly,but decrease the compressive strength.The research results can provide effective reference for modified rammed earth materials in Hanzhong rural traditional houses.
