This document takes saline soil in Binzhou as the research object using smelter slag as the soil stabilizer to solid saline soil in Binzhou, which has been proved achieving good performance of saline soil solidification. The results show that the soil solidification developed indoors can be used in combination with low-dose lime to achieve good performance in solidification of saline soil. The 7d strength is relatively higher than that of both ordinary lime stabilized soil and lime-fly ash stabilized soil, which completely meet the unconfined compressive strength requirements of the base layer in the current technical specifications. The soil stabilizer can improve the unconfined compressive strength of the saline soil, especially the post-14-day strength, and improve the immersion compressive strength and water stability of the cured saline soil. As the dosage of curing agent gets higher than seven percent, the 28d strength change of cured soil is no longer significant. The test result demonstrates that the dosage of curing agent should be less than seven percent.

In order to reveal the effect of type of admixture and its content on the strength of stabilized soil, this paper uses the sludge as raw soil and cement, fly ash as curing agent, and analyzes the strength characteristics of samples mixed stabilized according to certain content. Using the unconfined compressive strength test, the compressive strength of the samples is tested. The effect of curing agent type and its content on the compressive strength is investigated. From the experimental results, it can be seen that the content of cement and fly ash has much effect on the strength. The conclusions obtained can have some conference values on the foundation treatment and reuse of waste resources utilization.

Soil Stabilizer

The soil of the Loess Plateau is highly susceptible to erosion due to its distinct loess structure with poor water stability and disintegrates easily. Previous research has focused on improving soil strength without considering stability and ecological performance. Comprehensive improvements may be achieved by cross-linked polymers (CLPs), but their effect on loess structure remains unclear. In the present study, we investigate CLPs as a new organic soil stabilizer to improve soil aggregate stability. To determine the effect of CLPs on the stabilization of loess, a series of indoor tests was conducted to assess unconfined compressive strength, water stability, soil-water characteristics, and plant height. The stabilization mechanism was analyzed by comparing the microstructure, mineral composition, and features of functional groups of loess before and after treatment. The results showed that, compared with untreated loess, the unconfined compressive strength and anti-disintegration property of treated loess were significantly increased. The water retention capacity was improved, and the germination rate and growth of plants were promoted. Microscopic analysis showed that the use of CLPs did form new minerals in the loess or change the functional groups, rather, CLPs improved the microstructure, reduced the total volume of pores, and increased the degree of soil compaction. Field tests showed that the erosion of loess hillsides was effectively controlled by CLPs. Under the same erosive conditions, the slope surface treated with CLPs was more intact than the untreated slope surface. Our findings provide new strategies regarding the application of CLPs as soil stabilizers to control loess erosion and promote vegetation restoration.

The Relationship

TerraZyme as an enzymatic soil stabilizer was used in this research. The stabilized soil was mixed with TerraZyme in proper proportion to determine the relationship of unconfined compression strength and microstructure caused by the introduction of TerraZyme. The experimental results show that the unconfined compressive strength of stabilized soil with TerraZyme added is higher than that without TerraZyme. The micrographs of scanning election microscopy (SEM) indicate that the microstructure of the stabilized soil sample with TerraZyme added is denser than that without TerraZyme. This is because the particles of stabilized soil sample treated with TerraZyme are more coarse and blocky than those untreated with TerraZyme. The stabilized soil is with fewer pores than that without TerraZyme. This kind of compact microstructure should be the basis of higher unconfined compressive strength of stabilized soil with TerraZyme added.

An experimental work was conducted to study the use of factory-waste roof shingles to enhance the properties of fine-grained soil used in road works. Cement kiln dust (CKD), a cogenerated product of Portland cement manufacturing, was used as a stabilizing agent while the processed shingles were added to enhance the soil tensile strength. The effects of shingles on strength and stability were evaluated using the unconfined compressive strength, splitting tensile strength, and California Bearing Ratio (CBR) tests. The results showed that the use of CKD alone resulted in a considerable increase in the unconfined compressive strength but had a small effect on the tensile strength. The addition of shingles substantially improved the tensile strength of the stabilized soil. A significant reduction in the capillary rise and a slight decrease in the permeability were obtained as a result of shingle addition. An optimal shingle content of 10% is recommended to stabilize the soil.

There is large-area saline sludge which should be stabilized in China. However when cement is used as a stabilizer the strength and stabilization effect on the soil is relatively poor. In this paper, In this paper Portland cement PC is compared to a soft soil stabilizer A developed by the authors for use in stabilizing chloride saline soil from the Tianjin Binhai New Area. The strength of stabilized soil was tested by comparative Analysis, and XRD and SEM tests were used to analyze the hydrate types in stabilized soil. Preliminary tests results suggest that the salts present in hydraulic sludge and stabilizer A were able to react and formed a new hydrate----- Ca4Al2Cl2O6 • 10H2O which cannot be produced by cement alone, and which can greatly increase strength of stabilized soil.
