Description

Technical Field

[0001] The present invention relates to the field of building materials, and particularly relates to a method for producing a special anti-abrasion agent for hydraulic concrete by using high-titanium heavy slag. Background Art

[0002] Hydraulic concrete is in a harsh environment such as long-term water flow scouring and sediment abrasion for a long time, and has extremely high requirements for anti-abrasion performance. Traditional anti-abrasion agents mostly use materials such as silica fume and fly ash, but these materials have limited resources, high prices, and limited performance improvement.

[0003] High-titanium heavy slag is an industrial waste residue generated during the smelting process of vanadium-titanium magnetite. It has a large discharge volume and low utilization rate, which not only occupies land resources but also pollutes the environment. Due to the lack of hydration activity of the slag in high-titanium heavy slag and the presence of a large amount of mineral components such as perovskite and glaucochroite, it has good anti-abrasion effect. However, in the prior art, its utilization is mostly limited to the field of ordinary building materials, and its anti-abrasion potential has not been fully exerted. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that there is currently no technology to apply high-titanium heavy slag fine powder as the core component as an anti-abrasion agent in hydraulic concrete. The purpose is to provide a method for producing a special anti-abrasion agent for hydraulic concrete by using high-titanium heavy slag to solve the above problems.

[0005] The present invention is achieved by the following technical solutions:

[0006] A method for producing a special anti-abrasion agent for hydraulic concrete by using high-titanium heavy slag, comprising the following steps:

[0007] S1. Raw material pretreatment: drying, crushing, and grinding high-titanium heavy slag with a titanium content greater than 20% to a specific surface area ≥ 400 m 2 / kg to obtain high-titanium heavy slag fine powder;

[0008] S2. Batching: By weight, mixing 65 - 75 parts of high-titanium heavy slag fine powder, 12 - 18 parts of silica fume, 6 - 10 parts of activator, 1.5 - 3 parts of dispersant, and anti-abrasion enhancer evenly to obtain a mixed material;

[0009] S3. Grinding: Grinding the mixed material, and controlling the grinding fineness to a specific surface area ≥ 600 m 2 / kg to obtain a special anti-abrasion agent for hydraulic concrete.

[0010] When high-titanium heavy slag fine powder is directly applied to concrete, the following technical problems exist:

[0011] Insufficient activity: The hydration activity of high-titanium heavy slag fine powder is low, and it is difficult to form a dense structure when directly incorporated into concrete;

[0012] Weak interface bonding: The bonding force between slag particles and the cementitious matrix is insufficient, making it easy to peel off under scouring.

[0013] Ductility defect: Single slag powder cannot balance both compressive strength and impact toughness, resulting in easy cracking of concrete under dynamic loads.

[0014] Although high-titanium heavy slag powder contains high-hardness TiO2, its hydration reaction activity is much lower than that of cement, making it difficult to have an effective chemical reaction with the hydration products of cement in concrete (such as C-S-H gel). If slag particles only exist in concrete through physical filling, a weak transition zone will form in the interface area between them and the cement matrix. Under scouring loads, the particles are easy to peel off from the matrix, showing weak interface bonding. For materials with weak interface bonding, when impacted, cracks will preferentially expand along the slag-cement interface (rather than through the slag particles), resulting in ductility defects such as brittle fracture of the material.

[0015] Therefore, in the case of using high-titanium heavy slag as the core component, this invention adds silica fume, activator, dispersant, and impact abrasion resistance enhancer to obtain a special impact abrasion resistant agent for hydraulic concrete with good comprehensive performance.

[0016] Furthermore, the activator includes the following components: rare earth compound, sodium sulfate, calcium nitrate, nano-metakaolin, and electrolytic manganese slag.

[0017] This invention improves the activity of slag through the dual effects of ionic excitation and nano-filling. The introduction of calcium nitrate can accelerate the early dissolution of Al2O3 in high-titanium slag and form an ettringite (AFt) skeleton with sodium sulfate, solving the problem of slow strength growth of traditional activators in the later stage; nano-metakaolin promotes the directional growth of C-S-H gel by providing nucleation sites and reduces the porosity; electrolytic manganese slag is a by-product of the manganese electrolysis industry, mainly composed of MnSO4, Mn3O4, SiO2, and a small amount of heavy metal oxides. After MnSO4 dissolves in water, it releases Mn 2+ , which reacts with Al2O3 in the slag to form manganese aluminate hydrate (Mn-Al-H phase), accelerating the depolymerization of the slag vitreous body and enhancing the early hydration activity.

[0018] Furthermore, the rare earth compound includes one of CeCl3·7H2O, La(NO3)3·6H2O, and Y2O3.

[0019] Among them, CeCl3 can advance the early hydration heat release peak of high-titanium slag and increase the hydration degree at 72 h; Y 3+ forms a complex with SO4 2- , delaying the transformation of ettringite (AFt) to the monosulfate type and stabilizing the early skeleton; La 3+ adsorbs on the surface of nano-SiO2 to form "La-Si-O" active sites, promoting the secondary hydration reaction.

[0020] Further, the activator comprises components in the following mass fractions, based on the total amount of the activator: 0.1-1.2% of rare earth compound, 30-35% of sodium sulfate, 25-30% of calcium nitrate, 10-15% of nano-metakaolin, and 15-20% of electrolytic manganese slag.

[0021] Further, the impact and abrasion resistance enhancer comprises a linkage auxiliary agent and a toughening agent;

[0022] The toughening agent comprises polyacrylonitrile fiber modified by titanate;

[0023] The polyacrylonitrile fiber modified by titanate is prepared by the following method: immersing the polyacrylonitrile fiber in an NaOH solution for alkali treatment, then ultrasonically cleaning until neutral and drying for standby; diluting isopropoxytris(dioctylphosphate acyloxy)titanate and absolute ethanol according to a volume ratio of 1:5, stirring until clarified, then immersing the alkali-treated solid polyacrylonitrile fiber, with a liquid-solid ratio of 15:1, carrying out a constant-temperature water bath reaction at 60°C for 2-2.5 hours, then dropping acetic acid, continuing the reaction for 20-30 minutes, then filtering and drying to obtain the polyacrylonitrile fiber modified by titanate;

[0024] The linkage auxiliary agent comprises the following components: titanate coupling agent, zirconium phosphate, and polyvinyl butyral.

[0025] The polyacrylonitrile fiber modified by titanate is graft-modified by alkali treatment and titanate coupling agent, enhancing the fiber-matrix interface bonding. The modified polyacrylonitrile fiber bridges cracks, and the impact toughness is significantly improved compared with traditional slag concrete;

[0026] The titanate coupling agent forms Ti-O-Ti bonds with TiO2 in the high-titanium slag, bridging the slag and other components; zirconium phosphate releases Zr 4+ , promoting the depolymerization of the slag; polyvinyl butyral forms a flexible interfacial transition layer to buffer the impact stress.

[0027] Further, based on the mass of the high-titanium heavy slag, the addition amount of the titanate coupling agent is 3-5% of the mass of the high-titanium heavy slag, the addition amount of zirconium phosphate is 2-3% of the mass of the high-titanium heavy slag, the addition amount of polyvinyl butyral is 1-2% of the mass of the high-titanium heavy slag, and the addition amount of the polyacrylonitrile fiber modified by titanate is 1-2% of the mass of the high-titanium heavy slag.

[0028] Further, the impact and abrasion resistance enhancer further comprises an anti-wear phase, and the anti-wear phase comprises one or more mixtures of silicon carbide, corundum micropowder, and nano-silica sol.

[0029] Silicon carbide, corundum micropowder, and nano-silica sol directly improve the surface hardness of the material.

[0030] Further, the addition amount of the anti-wear phase is 5-6% of the mass of the high-titanium heavy slag.

[0031] Further, the dispersant is one or more of polycarboxylate water-reducing agents and naphthalene water-reducing agents.

[0032] The method for producing a special anti-abrasion and erosion agent for hydraulic concrete using high-titanium heavy slag includes the following specific steps:

[0033] S1. Raw material pretreatment: Dry, crush, and grind high-titanium heavy slag with a titanium content greater than 20% to a specific surface area of 450 m 2 / kg to obtain high-titanium heavy slag micropowder;

[0034] S2. Batching: By weight, mix 65 parts of high-titanium heavy slag micropowder, 18 parts of silica fume, 6 parts of activator, 1.5 parts of dispersant, and anti-abrasion and erosion enhancer evenly to obtain a mixed material;

[0035] S3. Grinding: Grind the mixed material, and control the grinding fineness to a specific surface area of 650 m 2 / kg to obtain a special anti-abrasion and erosion agent for hydraulic concrete.

[0036] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0037] 1. The method for producing a special anti-abrasion and erosion agent for hydraulic concrete using high-titanium heavy slag in the present invention takes high-titanium heavy slag as the core substance, and coordinates with silica fume, activator, dispersant, and anti-abrasion and erosion enhancer to obtain a special anti-abrasion and erosion agent for hydraulic concrete with good comprehensive performance;

[0038] 2. The method for producing a special anti-abrasion and erosion agent for hydraulic concrete using high-titanium heavy slag in the present invention designs a new activator, which solves the problem that the hydration activity of high-titanium heavy slag micropowder is low and it is difficult to form a dense structure when directly incorporated into concrete;

[0039] 3. The method for producing a special anti-abrasion and erosion agent for hydraulic concrete using high-titanium heavy slag in the present invention adds an anti-abrasion and erosion enhancer, which solves the problem that a single slag micropowder cannot balance the compressive strength and impact toughness.
