Embodiment 1
[0032] It is 6.8% to get organic matter content, and water content is the silty soil sample 1 of 87.1%, before test, remove soil sample impurity, take by weighing 600g soil sample, add different amount of silty soil composite curing agent (each component The weight percentages are: cement 46%, slag 34%, fly ash 15%, triethanolamine 5%), the mixture is stirred evenly to make 3 parallel cylinder samples of φ39.1×80mm, standard maintenance. The 14-day and 28-day unconfined compressive strengths are obtained as shown in Table 2:
[0033]Table 2 Soil sample 1 curing strength table
[0034]
Embodiment 2
[0036] Getting organic matter content is 7.1%, and water content is the muddy soil sample 2 of 89.5%, before test, remove soil sample impurity, take by weighing 600g soil sample, add different amount of muddy soil composite curing agent (each component The weight percentages are: cement 46%, slag 34%, fly ash 15%, triethanolamine 5%), the mixture is stirred evenly to make three φ39.1×80mm cylindrical parallel samples, standard curing. The 14-day and 28-day unconfined compressive strengths are obtained as shown in Table 3:

[0038]
Embodiment 3
[0040] It is 7.1% to get organic matter content, and water content is the muddy soil sample 3 of 91.1%, before test, remove soil sample impurity, take by weighing 600g soil sample, add different amount of muddy soil composite curing agent (each component The weight percentages are: cement 46%, slag 34%, fly ash 15%, triethanolamine 5%), the mixture is stirred evenly to make three φ39.1×80mm cylindrical parallel samples, standard curing. The 14-day and 28-day unconfined compressive strengths are obtained as shown in Table 4:
