Description

Technical Field

[0001] The present application relates to the field of construction engineering materials, and more specifically, to a fluidized solidified soil and a preparation method thereof. Background Technique

[0002] Silt has a high water content, low strength, poor permeability, and often contains harmful substances such as heavy metals. Traditional methods such as landfilling, dewatering, heat treatment, and reclamation by hydraulic filling have problems such as large land occupation, high cost, secondary pollution, and poor construction effects, which restrict the effective treatment and resource utilization of silt.

[0003] In related technologies, using a curing agent to solidify silt to prepare fluidized solidified soil is an effective way to utilize silt resources. Usually, Portland cement is used as the curing agent.

[0004] However, Portland cement lacks an expansion component and is difficult to fill in the gaps between soil aggregates to form a dense and stable structure with the soil, resulting in relatively low mechanical strength of the fluidized solidified soil. Once the amount of Portland cement is increased to enhance the strength, the fluidity of the fluidized solidified soil will decrease, restricting the wide application of the fluidized solidified soil. Summary of the Invention

[0005] In order to enable the fluidized solidified soil to have good fluidity and mechanical strength at the same time, the present application provides a fluidized solidified soil and a preparation method thereof.

[0006] In the first aspect, the present application provides a fluidized solidified soil, adopting the following technical solution:

[0007] A fluidized solidified soil includes silt and a curing agent. The water content of the silt is 100%, and the weight ratio of the silt to the curing agent is 100:(7 - 12);

[0008] The curing agent includes the following raw materials in parts by weight:

[0009] Granulated blast furnace slag 74 - 85 parts

[0010] Anhydrite 17 - 23 parts

[0011] High belite sulphoaluminate cement clinker 7 - 14 parts

[0012] Luffa cylindrica 20 - 26 parts

[0013] Bone glue 14 - 18 parts.

[0014] When Portland cement solidifies silt, it generally improves the overall stability and density of the fluidized solidified soil by generating C - S - H gel to fill the internal pores of the soil mass.

[0015] By adopting the above technical solution, due to the combination of granulated blast furnace slag, anhydrite and high belite sulphoaluminate cement clinker, when solidifying the sludge, not only C-S-H gel can be generated, but also AFt crystals that cannot be formed by Portland cement can be generated, converting a large amount of free water into crystal water, improving the cohesion between soil particles, making the overall structure of the fluidized solidified soil more dense and having fewer pores. In the formed fluidized solidified soil system, columnar AFt crystals serve as hard structure supports, while loofah sponges have a reticular framework structure and can serve as soft structure supports inside the fluidized solidified soil, intersecting and overlapping with the columnar AFt crystals to form a framework structure. C-S-H gel agglomerates soil particles, effectively filling the internal pores of the fluidized solidified soil. Bone glue can promote the re-aggregation of free colloidal particles through adsorption bridging on the loofah sponge, enabling a dense and stable structure to be formed inside the fluidized solidified soil. Each raw material cooperates with each other, enhancing the mechanical strength of the fluidized solidified soil; at the same time, the loofah sponge has many fine pores, which can effectively store water and can effectively maintain the fluidity of the fluidized solidified soil. Therefore, the fluidized solidified soil has good fluidity and mechanical strength at the same time.

[0016] Optionally, the weight ratio of the sludge to the solidifying agent is 100:9.

[0017] By adopting the above technical solution, with the solidifying agent in the above addition amount, the improvement effect on the fluidity and mechanical strength of the fluidized solidified soil is more significant.

[0018] Optionally, the loofah sponge is crushed into pieces with a diameter of 10 - 20 mm before use.

[0019] By adopting the above technical solution, with the loofah sponge of the above specification, the ability to improve the mechanical strength of the fluidized solidified soil is better.

[0020] Optionally, the particle size of the bone glue is 2 - 5 mm.

[0021] By adopting the above technical solution, with the bone glue of the above specification, the ability to improve the mechanical strength of the fluidized solidified soil is relatively good.

[0022] Optionally, the solidifying agent further includes an anti-dispersion component, and the anti-dispersion component includes kapok fiber, bagasse and konjac gum. In the solidifying agent, the added weight of kapok fiber is 7 - 9 parts, the weight of bagasse is 5 - 7 parts, and the weight of konjac gum is 4 - 6 parts.

[0023] By adopting the above technical solution, since the anti-dispersion components are kapok fiber, bagasse and konjac gum, the kapok fiber has a unique hollow structure, which can guide the flow of free water to improve the fluidity of the flowable solidified soil. However, the kapok fiber has poor cohesion. After absorbing water, the konjac gum forms a film and covers the kapok fiber, which can not only improve the cohesion of the kapok fiber, reduce the excessive dispersion of the kapok fiber, but also form an elastic gel under the action of alkaline substances in each particle of the solidified soil for the dispersion of inter-particle stress. The bagasse contains bagasse fiber, which can effectively adsorb free particles. Under the adhesion of konjac gum and combined with kapok fiber, it can promote the free particles and part of the free water guided by kapok fiber to further participate in the hydration reaction, thereby reducing the dispersion of particles and improving the mechanical strength.

[0024] Optionally, the length of the kapok fiber is 5-8 mm.

[0025] By adopting the above technical solution, using the kapok fiber of the above specifications can play a better role in improving the fluidity of the solidified soil.

[0026] Optionally, the length of the bagasse is 3-5 mm.

[0027] By adopting the above technical solution, using the bagasse of the above specifications can play a better role in improving the mechanical strength of the solidified soil.

[0028] In the second aspect, the present application provides a preparation method of flowable solidified soil, adopting the following technical solution:

[0029] A preparation method of flowable solidified soil includes the following steps:

[0030] (1) Prepare each raw material in the curing agent according to the above ratio, mix evenly to obtain the curing agent;

[0031] (2) Measure the initial moisture content of the original silt, then calculate the mass of tap water required according to the requirement that the preset moisture content of the silt is 100%, and then add the corresponding amount of water to soften the sticky and hard components in the silt, and evenly mix each component in the silt to achieve homogenization;

[0032] (3) Add the curing agent to the homogenized silt according to the ratio and mix evenly.

[0033] By adopting the above technical solution, the prepared flowable solidified soil has good fluidity and mechanical strength.

[0034] In the third aspect, the present application provides a preparation method of flowable solidified soil, adopting the following technical solution:

[0035] A preparation method of flowable solidified soil includes the following steps:

[0036] (1) Prepare each raw material in the curing agent according to the above ratio. First, mix the raw materials in the anti-dispersion component evenly, and then mix them with other raw materials in the curing agent evenly to obtain the curing agent.

[0037] (2) Measure the initial moisture content of the original sludge, then calculate the mass of tap water required according to the requirement that the preset moisture content of the sludge is 100%, and then add the corresponding amount of water to soften the sticky and hard components in the sludge, and mix the components in the sludge evenly to achieve homogenization.

[0038] (3) Add the curing agent to the homogenized sludge and mix evenly.

[0039] By adopting the above technical solution, the anti-dispersion component is prepared first, which can effectively exert the maximum effect of the anti-dispersion component, and the prepared fluidized solidified soil has good fluidity and mechanical strength.

[0040] In summary, the present application has the following beneficial effects:

[0041] 1. Since the present application adopts a combination of granulated blast furnace slag, anhydrite and high belite sulphoaluminate cement clinker, and adds loofah sponge and bone glue, when solidifying the sludge, C-S-H gel and AFt crystals are generated. The loofah sponge and columnar AFt crystals intersect and overlap to form a framework structure. The C-S-H gel agglomerates soil particles, effectively filling the internal pores of the fluidized solidified soil. The bone glue can promote the re-aggregation of free colloidal particles through adsorption bridging on the loofah sponge, so that a dense and stable structure is formed inside the fluidized solidified soil. The raw materials cooperate with each other to enhance the mechanical strength of the fluidized solidified soil; at the same time, the loofah sponge has many fine pores, which can effectively store water and can effectively maintain the fluidity of the fluidized solidified soil. Therefore, the fluidized solidified soil has good fluidity and mechanical strength at the same time.

[0042] 2. In the present application, an anti-dispersion component is added to the curing agent, using kapok fiber, bagasse and konjac gum. The kapok fiber has a unique hollow structure, which can guide the flow of free water to improve the fluidity of the fluidized solidified soil. After absorbing water, the konjac gum forms a film and covers the kapok fiber, which can not only improve the cohesion of the kapok fiber, reduce the excessive dispersion of the kapok fiber, but also form an elastic gel under the action of alkaline substances in each particle of the solidified soil for the dispersion of inter-particle stress. The bagasse contains bagasse fiber, which can effectively adsorb free particles. Under the adhesion of konjac gum, it combines with kapok fiber, which can promote the further participation of free particles and part of the free water guided by kapok fiber in the hydration reaction, thereby reducing the dispersion of particles and improving the mechanical strength.

[0130] Performance detection test

[0131] Test method

[0132] 1. Fluidity:

[0133] Measurement of fluidity: Refer to the "Test Method for Air-Entrained Mortar and Air-Entrained Grout" formulated by the Japan Road Association. Use a hollow acrylic glass cylinder with an inner diameter of 80 mm and a height of 80 mm to measure the fluidity of the fluid-solidified soil. The specific test method is to place the test cylinder on a smooth glass plate. After the fluid-solidified soil is mixed, slowly pour it into the cylinder until it is full. After slowly and evenly lifting the cylinder, measure its maximum slump expansion diameter and its vertical diameter, and take the average of the two as the fluidity of the solidified soil. See Table 3 for the test results.

[0134] 2. Mechanical strength

[0135] Molding and curing of specimens: Pour the mixed fluid-solidified soil into a prism with dimensions of 40 mm * 40 mm * 160 mm to make it naturally dense. Use a spatula to scrape the surface of the steel mold flat and stick on plastic wrap, and cure it at room temperature for 24 - 36 h. After demolding, place it in a standard curing box (temperature 20 ± 2 °C, relative humidity above 95%), and use it after curing to the required age for the test.

[0136] Referring to "10.1 Determination of flexural strength", "10.2 Determination of compressive strength" and "11 Test results" in "Test Method for Strength of Cement Mortar (ISO Method)" (GB / T 17671-2021), an electronic pressure testing machine was used to conduct a flexural strength test on the specimens at a rate of (50±10) N / s and a compressive strength test on the specimens at a rate of (2400±200) N / s to obtain the test results, as shown in Table 3 for details.

[0140]

[0141]

[0142] Combining Example 2 and Comparative Example 1 and referring to Table 3, it can be seen that compared with using portland cement as the curing agent, the fluid-solidified soil prepared with the curing agent of the present application has better mechanical strength and fluidity.

[0143] The reasons are analyzed as follows: The combination of granulated blast furnace slag, anhydrite and high belite sulphoaluminate cement clinker generates C-S-H gel and AFt crystals when solidifying silt, converting a large amount of free water into crystal water and improving the cohesion between soil particles; after adding loofah sponge and bone glue, the columnar AFt crystals act as a hard structure support and the loofah sponge acts as a soft structure support, and the two intersect and overlap to form a framework structure. The C-S-H gel agglomerates the soil particles and effectively fills the internal pores of the fluid-solidified soil; the bone glue promotes the re-aggregation of free colloidal particles through adsorption bridging on the loofah sponge, making the internal structure of the fluid-solidified soil dense and stable. Each raw material cooperates with each other to enhance the compressive strength and flexural strength of the fluid-solidified soil. At the same time, the loofah sponge has many fine pores, which can effectively store water and can effectively maintain the fluidity of the fluid-solidified soil. Therefore, the prepared fluid-solidified soil has both good fluidity and mechanical strength.

[0144] Combining Example 2, Comparative Examples 1-10 and referring to Table 3, it can be seen that when using the compound of granulated blast furnace slag, anhydrite, high belite sulphoaluminate cement clinker, loofah sponge and bone glue, the effect can be maximized, and the fluidity and mechanical strength of the prepared solidified soil are significantly improved.

[0145] Combining Examples 1-3, Examples 6-9 and referring to Table 3, it can be seen that limiting the diameter of the loofah sponge and the particle size of the bone glue helps to improve the fluidity and mechanical strength of the solidified soil, especially with a large upward trend in terms of mechanical strength.

[0146] Combining Examples 2, 4, and 5 and referring to Table 3, it can be seen that when the weight ratio of silt to the curing agent is 100:9, the improvement effect on the fluidity and mechanical strength of the fluidized solidified soil is more significant.

[0147] Combining Example 2, Example 11 and referring to Table 3, it can be seen that after adding an anti-dispersion component to the curing agent, the fluidity and mechanical strength of the fluidized solidified soil are further significantly improved.

[0148] The reasons are analyzed as follows: The anti-dispersion component uses kapok fiber, bagasse and konjac gum. Kapok fiber has a unique hollow structure, which can guide the flow of free water to improve the fluidity of the fluidized solidified soil. However, the kapok fiber has poor cohesion. After konjac gum absorbs water, it forms a film and covers the kapok fiber, which can not only improve the cohesion of the kapok fiber, reduce the excessive dispersion of the kapok fiber, but also form an elastic gel under the action of alkaline substances in each particle of the solidified soil for the dispersion of inter-particle stress. Bagasse contains bagasse fiber. The transverse section of the bagasse fiber shows an irregular multi-layer wall hollow tube cavity structure, and multiple hollow microtubes are bundled together to form a bundled structure; the longitudinal surface of the bagasse fiber is a corrugated structure arranged in parallel at equal intervals, which can effectively adsorb free particles. Under the adhesion of konjac gum, combined with kapok fiber, it can promote the free particles and part of the free water guided by kapok fiber to further participate in the hydration reaction, thereby reducing the dispersion of particles and improving the mechanical strength.

[0149] Combining Examples 10 - 16 and referring to Table 3, it can be seen that limiting the lengths of kapok fiber and bagasse can effectively improve the fluidity and mechanical strength of the fluidized solidified soil.

[0150] Combining Example 2, Example 11, Examples 18 - 23 and referring to Table 3, it can be seen that only when the three substances in the anti-dispersion component are compounded and combined with other raw materials in the curing agent, can the fluidized solidified soil with the best performance in both fluidity and mechanical strength be obtained.

[0151] Combining Example 11 and Example 17 and referring to Table 3, it can be seen that when the anti-dispersion component is not premixed, the performance of the prepared fluidized solidified soil is far inferior to that of the step-by-step premixed fluidized solidified soil.

[0152] This specific embodiment is only an explanation of the present application, and it is not a limitation of the present application. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
