TABLE 3 test results of examples 1 to 9 and comparative examples 1 to 5
As can be seen from the data in Table 3, the composite soil stabilizer prepared by the method has better strength and water resistance by adding the prepared composite modifier.
According to the detection data of the embodiments 1 to 4, the raw materials in the embodiment 3 are well proportioned, and the prepared composite soil stabilizer is higher in unconfined compressive strength, lower in water absorption rate, higher in water stability coefficient and lower in permeability coefficient after being used for soil curing for 7 days.
According to the detection data of the embodiment 3 and the embodiments 5 to 6, the compound modified material of the preparation example 2 is good in proportion, and the compound modified material prepared by the preparation example 2 is used in the preparation process of the compound soil stabilizer, so that the compound soil stabilizer obtained after being used for soil curing has high unconfined compressive strength, low water absorption, high water stability coefficient and low permeability coefficient after being used for soil curing for 7 days.
By combining the detection data of the examples 5 and 7-9, the composite soil curing agent obtained can be used for measuring that the higher the unconfined compressive strength, the lower the water absorption rate, the higher the water stability coefficient and the lower the permeability coefficient of the composite soil curing agent in 7 days after the composite modifying agent is used for soil curing.
The test data of comparative examples 4-5 show that when the addition amount of the composite modified material is lower or higher, the performance of each aspect of the composite modified material is not the same as that of the composite modified material adopted in the examples of the application, the obtained effect is good, and when the addition amount of the composite modified material is 30kg, after the composite soil curing agent is used for curing soil, the unconfined compressive strength of 7 days is 16.98MPa, the water absorption rate in water immersion is 0.82%, the water stability coefficient is 91.58%, and the permeability coefficient is 7 multiplied by 10 -9 。
It can be seen by combining the test data of comparative examples 1-3 and example 1 that when one of the acrylic acid high molecular polymer, the sulfonated oil and the hybrid fiber in the composite modified material is added in an amount of 0, the prepared composite modified material is used for a composite soil curing agent, and the unconfined compressive strength, the water absorption rate, the water stability coefficient and the permeability coefficient of the composite modified material are not as good as those of the composite soil curing agent when the acrylic acid high molecular polymer, the sulfonated oil and the hybrid fiber are added simultaneously for 7 days, which indicates that the acrylic acid high molecular polymer, the sulfonated oil and the hybrid fiber have a synergistic effect.
