Description
Technical Field
The invention relates to the technical field of anti-caking agents, in particular to a novel anti-caking agent for a soil body curing agent, a related soil body curing agent, and preparation and application thereof.
Background
At present, soil body curing agents are used in various aspects, such as construction of various roads, railway construction, mud flat construction, land arrangement, river and lake management, airport construction and the like; the method is suitable for pit base layer, curtain grouting, pit filling, rock slope consolidation, beach planting, rock slope greening, vegetation recovery, soil layer spraying, sha Po consolidation and the like; the method is used for landfill construction, lake and river treatment, farmland water conservancy, harbor construction and the like; the method is used for beach planting, rock slope greening, vegetation recovery, sha Po consolidation and the like; the method is used for sludge consolidation, soft foundation treatment, beach construction and the like.
The inorganic compound soil body curing agent takes cement and lime as main raw materials, but the cement production process has high energy consumption and high cost, and discharges a large amount of carbon dioxide gas to pollute the environment (about 100-DEG electricity is needed for each ton of cement production, and about 500 kg of CO is released) 2 ). Lime as curing agent is strictly neededThe grid controls the mixing amount, and the too high mixing amount often causes the problems of soil body cracking and the like. Along with the development of industrialization, various industrial wastes bring serious harm to the environment where human beings depend on and live, and industrial slag and other wastes are developed and utilized to form a soil body curing agent which becomes an important way for recycling the solid wastes.
Bulk solid wastes such as fly ash, carbide slag, gypsum, steel slag, aluminum slag, red mud, sludge incineration slag, household garbage incineration ash and various building solid wastes are used as waste residues with more and more discharge, the storage quantity is huge, a large amount of land is occupied, and serious environmental pollution is caused. The curing agent is prepared from the industrial wastes, so that the recycling of the industrial wastes can be realized, the adverse effect of the industrial wastes on the environment is eliminated, the problems of high energy consumption and high emission caused by using the traditional inorganic compound curing agent are solved, the engineering cost is saved, the curing effect is improved, and the cost is lower.
However, in the preparation process of the soil body curing agent, the curing agent has unstable performance due to various industrial solid waste sources, complex components and different water contents. The invention mainly focuses on the agglomeration problem in performance indexes. Agglomerating and caking of the curing agent materials during mixing, transporting and storing can greatly influence the use of the curing agent.
In order to avoid agglomeration and caking of solid waste, one solution thought mentioned in the prior art is to dry the solid waste such as steel slag, carbide slag, gypsum and the like, and although the problem of agglomeration of the water-containing raw materials can be solved by using a drying mode, the energy consumption is high and the production efficiency is low. Another way is to screen directly, but this would result in a loss of significant amounts of material. In yet another way, which focuses on consuming moisture from the sludge, rather than from the raw materials in the composition of the curing agent, CN111439987a, for example, discloses a beach sludge curing agent in which an enhanced activator (components of 16-23% calcium oxide, 46-66% sodium silicate, 16-27% calcium chloride and 1-7% polyacrylamide) is used, which rapidly consumes moisture from the sludge and gives off heat to increase the temperature of the sludge, thereby increasing the hydration rate of the potentially active material. As another example, KR102117552B1 discloses a curing composition for reinforcing a low cement soft soil foundation and a soft soil foundation treatment method using the same, which disclose that a circulating resource (industrial by-product) containing a large amount of calcium oxide is effective in securing early strength, thereby reducing moisture in the soft soil foundation to be reinforced. In addition, the water in the soft soil foundation can be evaporated by the heat generated by the reaction, so that the effect can be further improved. It follows that the use of cyclic resources (industrial by-products) containing a large amount of calcium oxide is mainly based on the consideration of ensuring early strength and evaporating water in soft soil foundations.
In the previous research, the problems of agglomeration and caking of the raw materials can be well solved by reasonably selecting the raw materials and combining the functional components with the dispersing components. The water-reactive raw materials such as calcium oxide are not good in effect, the problems of serious heat release, overlarge expansion rate and the like can occur, and the performance is better when the functional components are matched with inert dispersed components.
For the anti-caking agent, it is used in other fields such as foods, fertilizers, cosmetics, synthetic detergents, etc. Currently, commonly used anticaking agents in China include potassium ferrocyanide, sodium aluminosilicate, tricalcium phosphate, silicon dioxide and microcrystalline cellulose. Worldwide, there are also anti-agglomerating agents such as aluminum silicate, calcium alumino silicate, calcium stearate, magnesium carbonate, magnesium oxide, magnesium stearate, magnesium phosphate, magnesium silicate, kaolin, talc and sodium ferrocyanide.
US9873637B2 relates to a process for preparing an anhydrite mortar composition, wherein an anti-caking agent is used, which is calcium carbonate, kaolin, alumina or silica, mineral or organic colorant (average particle size advantageously being of the order of 0.1 to 100 μm, preferably 0.5 to 5 μm, more preferably 1 μm). The anti-caking agent of the system is mixed with fatty alcohol, defoamer and the like to prepare an additive, the addition amount is small, and the problem to be solved is to reduce the film formation on the horizontal surface of the hydraulic composition, but not the caking and caking problems of raw materials.
US20180297897A1 discloses a solid particulate calcium nitrate composition comprising a solid particulate silicate in which an anti-caking agent is added in order to prevent caking caused by hygroscopicity of the calcium nitrate powder, the anti-caking agent consisting of a solid particulate silicate having an average particle size of between 0.05 μm and 750 μm, wherein the solid particulate silicate is present in an amount of from 0.01 to 2% by weight.
US20090320645A1 discloses a granulated blast furnace slag anticaking agent comprising component a: gluconic acid and/or salts thereof; component B: copolymers of C5-6 alkenes and one or more monomers selected from maleic anhydride, maleic acid or esterification products thereof, (meth) acrylic acid or esterification products thereof and/or salts thereof.

JPH0824819a discloses waste treatment materials and waste treatment methods, mentioning that anti-caking agents include silica gel, diatomaceous earth, bentonite, activated clay, stearate, alkyl amine acetate, palm oil, acid clay, activated bauxite, activated alumina, etc., but the application area is far from soil curing agents.
JP6183020B2 discloses an anti-caking method and an anti-caking agent which is composed of ash and fly ash and is selected from one or two or more of a higher fatty acid metal salt having 10 or more carbon atoms and hydrophobic fumed silica. The average particle diameter of the hydrophobic particles isThis patent deals mainly with the problem of anti-caking of open air powders.
JP2015054807A uses an anti-consolidation component selected from phosphonic acid, gluconic acid and salts thereof in preventing consolidation of blast furnace slag. The anti-caking agent of this patent is an aqueous solution.

The anti-caking agent is silicon dioxide.
CN111094511a discloses an anti-caking agent for soil, which comprises lignin and diatomaceous earth as active ingredients, wherein the lignin has a molecular weight peak in the range of a molecular weight 10,000 ~ 40,000 at a wavelength of 254nm in GPC molecular weight analysis using a UV detector. The addition of the anti-caking agent in this patent is mainly aimed at improving the caking of soil and the poor growth effect of plants.
CN108191322a discloses a dry-mixed mortar and a preparation method thereof, and the mixed anti-caking agent used comprises phosphorous slag and an exciting agent, so that the dry-mixed mortar is mainly prevented from being dried and knotted in the storage process, and the quality guarantee period is prolonged.

From the prior art, no special anti-caking agent is available for the soil curing agent field.
Disclosure of Invention
The concept of an anti-caking agent is well studied in the fields of foods, fertilizers, cosmetics and the like, but no related research is available in the field of soil curing agents. The inventor has carried out series of attempts to form an anti-caking agent by using a functional component and a dispersing component, and the invention continues to carry out further deep mechanism and effect researches. On the one hand, the invention aims to provide a novel anti-caking agent which is suitable for the field of soil solidifying agents, and preparation and application thereof. The invention adopts specific disperse components and tries light porous material and mesoporous material by reasonably selecting and matching raw materials, thereby well solving the anti-caking problem of the curing agent.
On the other hand, the invention aims to provide a premix and preparation and application thereof, and not every raw material can cause agglomeration and caking in the field of soil curing agents and in the fields of concrete, filling materials, backfilling materials and roadbed materials. According to the analysis of the present invention, the wet solid waste with the water content of above 0.5%, especially with the water content of above 1%, and the solid waste with the water content of above 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14% or 15% are easy to cause agglomeration and caking. The problem of agglomeration and caking can be well solved by premixing the solid waste with the water content and the anti-caking agent.
The wet solid waste according to the present invention is, unless otherwise specified, solid waste containing a certain amount of water/adhering water, particularly solid waste that tends to agglomerate or agglomerate during use, and specifically solid waste having a water content of 0.5% or more, particularly solid waste having a water content of 1% or more, and the above-defined water content of 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14% or 15% or more falls within this range. The water content is calculated: the wet solid waste weight is a, the weight after drying to constant weight at low temperature is b, and the water content is = (a-b)/b (the result is converted into percentage).
It should be emphasized here that the type of the solid waste is not particularly limited, as long as it is suitable for applications in the field of soil hardening agents and in the fields of concrete, filling materials, backfill materials, roadbed materials, and the like, for example. Meanwhile, even the same solid waste has quite different water contents due to different sources, and only the water contents of more than 0.5%, especially more than 1%, and further more than 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14% and 15% are needed to be treated. In addition, if the wet solid waste having a water content of 1% or more is dehydrated by a treatment such as drying, it is not necessary to additionally mix the wet solid waste with the anti-caking agent, and it is permissible to add the anti-caking agent in this case.
In another aspect, the invention aims to provide a soil body curing agent with excellent performance, and preparation and application thereof, wherein the agglomeration and agglomeration problems of the soil body curing agent in the processes of material mixing, transportation and storage can be well solved by adding the anti-agglomeration agent or the premix containing the anti-agglomeration agent, and meanwhile, the stability of the performance of the soil body curing agent can be ensured.
Finally, the invention aims to provide construction powder for stirring piles, construction slurry for stirring piles, solidified soil, concrete, filling materials, backfilling materials, roadbed materials and the like which use related anti-caking agents or premixes containing the anti-caking agents and soil curing agents, and the related products have stable performances and meet performance indexes in practical application.
In the prior series of researches of the inventor, the anti-caking agent is prepared by matching water reactive components such as calcium oxide, magnesium oxide, anhydrous gypsum, semi-hydrated gypsum and the like with dispersing components, so that the caking and caking problems are greatly improved, and the screen residue of raw materials is less. However, previous studies have considered that a water reactive component is necessary, which removes water from the raw material by reaction with water, thereby achieving the effect of improving caking and agglomeration. As the inventors have continued their studies, they have unexpectedly found that the anti-caking effect is essentially due to two aspects, on the one hand the reaction of the water-reactive component with water; on the other hand, the physical dispersion of the dispersed components is also of critical importance. The aqueous materials are susceptible to agglomeration into clumps/clusters due to the presence of water, but when inert dispersing components are added, the dispersing components prevent agglomeration of the materials.
Based on the foregoing important findings, the inventors have devised a novel anti-agglomerating agent that can solve the agglomeration problem by relying only on inert dispersing components.
Specifically, the invention provides the following technical scheme:
an anti-caking agent for a soil body curing agent only comprises a dispersing component and does not comprise a functional component, wherein the dispersing component is an inert component and does not react with water; the functional component is a water reactive component. Further, the anti-caking agent according to the present invention does not comprise free calcium oxide and free magnesium oxide.
In one embodiment, the dispersing component is selected from one or more of a lightweight porous material, a mesoporous material. Further, the lightweight porous material is selected from diatomaceous earth. The mesoporous material is selected from mesoporous carbon or mesoporous silicon. Further, the fineness of the lightweight porous material is 500 mesh or more, preferably 600 mesh, 800 mesh, 900 mesh or 1000 mesh or more. The fineness of the mesoporous material is more than 500 meshes, preferably more than 600 meshes, 800 meshes, 900 meshes or 1000 meshes.
In one embodiment, the dispersing component is selected from one or more of quartz powder, bentonite, kaolin, heavy calcium carbonate, light calcium carbonate, and silica fume. The above components of the present invention may be prepared by themselves or may be obtained from commercial sources, such as by the chemical industry of the ridge, ke Mi Ou, guo Yao, shengmai, etc.
Further, the fineness of the dispersed component is 200 mesh or more, preferably 300 mesh or more.

Advantageous effects
Compared with the prior art, the technical scheme provided by the invention has the following remarkable effects:
(1) Before the research of the inventor, the soil body curing agent field and the concrete field have no special anti-caking agent to solve the caking and caking problems of raw materials. The invention well solves the problems of agglomeration and caking of raw materials by reasonably selecting and matching the raw materials.
(2) The present invention has for the first time found that the anti-caking effect comes substantially from two aspects, on the one hand the reaction of the water-reactive component with water; on the other hand, physical dispersion of the dispersed components; by carefully screening the raw materials, a very good anti-caking effect is achieved by only relying on the dispersing components.
(3) The porous material and the mesoporous material have physical water absorption effect and can show good anti-caking effect.
Drawings
Fig. 1 shows the appearance of the premix of example 2 after sieving, wherein the anti-caking agent is 200 meshes of quartz powder, 400 meshes of quartz powder, 200 meshes of heavy calcium carbonate (namely heavy calcium carbonate), 200 meshes of light calcium carbonate (namely light calcium carbonate) and 800 meshes of diatomite in sequence from left to right.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Example 1:
the anti-caking agent was mixed with gypsum (water content 6.2%) in the weight ratio shown in Table 1 to obtain a premix, and the premix state was observed and recorded in Table 1. The state is mainly to observe whether the material is hardened or not, whether all the screened residues are soft or not, whether the materials can be manually crushed or not, and the amount of the screened residues.
As can be seen from table 1, for quartz powder, fineness is required to be more than 400 meshes to obtain a good anti-caking effect; for diatomite, the anti-caking effect is very good (only 800-mesh and 1250-mesh diatomite is purchased, and the qualitative experiment adopts 800 meshes here); the light calcium carbonate with 200 meshes has better anti-caking effect; however, for heavy calcium carbonate, the anti-caking effect of 200 meshes of heavy calcium carbonate still needs to be improved, and the anti-caking effect can be better achieved by more than 300 meshes.
TABLE 1 premix status
Example 2:
further experiments were carried out according to the preferred fineness of the material obtained from the qualitative experiments of example 1. The anti-caking agent and gypsum (water content 6.2%) were mixed according to the weight ratio of Table 2 to obtain a premix, 10 kg/phi 15cm weight pressure was applied, and after 5 days, the premix was sieved through a 2.36mm standard sieve, the conditions after sieving were shown in FIG. 1, and the screen residue data were shown in Table 2. From experimental data, the screened inert material with specific fineness can meet the anti-caking effect.
TABLE 2 premix run out test results
In previous studies, pre-mix samples spiked with calcium oxide alone showed significant caking with a sieve balance of 60.0%; when calcium oxide is blended with inert components (quartz powder), the agglomeration phenomenon of the curing agent can be greatly reduced, and the screen allowance is only 4.5 percent (specifically shown in table 3). The addition of the inert component alone also reduces the caking of the curative/premix, but the inert component does not absorb water and is slightly less effective than the re-addition of calcium oxide to the inert component.
TABLE 3 test results of the screen residue test of the calcium oxide-containing premix
Example 3:
the anti-caking agent was mixed with gypsum (water content 6.2%) according to the weight ratio of Table 4 to give a premix, 10 kg/15 cm weight, and after 5 days, passed through a 2.36mm standard sieve, the screen residue data are shown in Table 4.
After further expanding the range of experimental materials, it was found that the selection of poorly water-soluble substances generally has a certain anti-agglomerating effect when the particle size is small, but different materials have different properties and preferred fineness.
TABLE 4 premix run out test results
Example 4:
according to the weight ratio of the raw materials in Table 5, the anti-caking agent and gypsum are firstly mixed to obtain a premix, and then the premix is mixed with cement (PO 42.5 in the south of Pinghu) and slag powder to prepare the soil body curing agent. According to the water: soil body curing agent is 1.5:1, soil body curing agent: the engineering soil was tested at 1:5 and the results are reported in Table 5.
TABLE 5 results of curative compressive strength test
Table 6 shows the relationship between the holding time and the strength, and the strength was decreased with the increase of the holding time, probably due to the higher moisture content and the lack of calcium oxide. It can be seen that the individual incorporation of inert components is more suitable for ready-to-use scenarios.
