Description
Technical Field
The invention relates to the field of cement processing aids, in particular to a steel slag hydration-promoting modified composition and a preparation method thereof.
Background
The steel slag is solid waste generated in the process of smelting crude iron. The data of the national statistical bureau show that about 1 ton of steel slag is discharged when 3 tons of crude steel are produced in China, and the discharge amount of the steel slag is about 3 hundred million tons. Although the steel slag has higher compactness and hardness, the engine oil is used as the potential of coarse and fine aggregates for concrete, but the hidden danger of volume stability exists because the engine oil contains a certain amount of free calcium oxide and free magnesium oxide. Therefore, at present, steel slag has not been largely used as a substitute for natural aggregate for concrete. The blood components of the steel slag are very similar to those of silicate cement clinker, and the steel slag has the name of 'inferior cement clinker'. Grinding the steel slag to prepare the steel slag mineral admixture to replace part of cement is a main technical approach for realizing high added value application of the steel slag. Because the steel slag has a mineral phase with higher hardness and a simple substance with stronger toughness, the steel slag is difficult to grind and activate, the particle size of the traditional steel slag mineral admixture is 15-60 um, and the cement substitution amount is usually lower than 10%.
Free calcium oxide and free magnesium oxide in the steel slag powder can be hydrated to generate expansion in the construction service process, although the concrete member is not cracked, the porosity of the concrete member can be increased, the strength of the concrete member can be reduced, and the service performance of the concrete member can be influenced. With the improvement of environmental protection requirements, in order to meet the requirements of environmental protection treatment and product utilization of steel slag, the problems of steel slag in cement and concrete application are urgently needed to be solved.
Therefore, the application provides a steel slag hydration-promoting modified composition which can effectively promote the steel slag hydration.
Disclosure of Invention
In order to solve the above problems, the first aspect of the present invention provides a steel slag hydration-promoting modified composition, which comprises the following raw materials by mass: 10-30% of metal silicate, 5-20% of carbon material slurry, 12-35% of organic amine agent, 1-5% of auxiliary agent and the balance of deionized water.
Preferably, the metal silicate is at least one of sodium silicate, aluminum silicate, lithium silicate, potassium silicate and magnesium silicate.
Preferably, the metal silicate is sodium silicate.
Preferably, the carbon material slurry is at least one of graphene slurry, graphite slurry, graphene oxide slurry, carbon powder slurry, carbon quantum dot slurry and carbon nanotube slurry.
As a preferable scheme, the carbon material slurry is graphene slurry.
As a preferred scheme, the preparation method of the graphene slurry comprises the following steps: weighing 0.2-3 g of polycarboxylate to dissolve in 50g of water until the polycarboxylate is completely dissolved; and adding 0.5-5 g of solid graphene into the aqueous solution, stirring for 30-70 min, mixing, adding the rest water to make the total amount of the water be 100g, emulsifying for 0.2-2 h by using a shearing emulsifying machine, and standing to make the graphene not delaminated.
As a preferred embodiment, the polycarboxylate is sodium polycarboxylate.
As a preferable mode, the mass ratio of the polycarboxylate to the graphene is 1.
As a preferable scheme, the organic amine is at least one of diisopropanolamine, triisopropanolamine, diethanolamine, triethanolamine, tetrahydroxypropylethylenediamine and tetrahydroxyethylethylenediamine.
As a preferable scheme, the steel slag hydration-promoting modified composition also comprises modified oxide nano particles with the content of 10-15 wt%; the preparation method of the modified oxide nanoparticles comprises the following steps: (1) Dissolving succinic anhydride in a DMF solution, adding a certain amount of (3-aminopropyl) triethoxysilane, heating and stirring for 1-2 hours at the water bath temperature of 60-80 ℃; (2) Then, dropwise adding a DMF solution containing zinc oxide into the reaction solution, and continuously stirring for reaction for 1-1.5 hours to obtain pretreated zinc oxide particles; (3) Mixing the pretreated zinc oxide particles with 2-methylimidazole and zinc nitrate, adding an ethanol solvent, carrying out ultrasonic polymerization for 10-15 hours in a water bath ultrasonic device of 300-500W, washing and drying the obtained product, and obtaining the modified oxide nanoparticles.
In a preferred embodiment, the mass ratio of the succinic anhydride to the (3-aminopropyl) triethoxysilane is 3-5.
As a preferable scheme, the ultrasonic polymerization reaction time under the water bath ultrasonic device is 11 to 13 hours.
In a preferred embodiment, the modified oxide nanoparticles have an average particle diameter of 300 to 500nm.
In the application, the zinc oxide particles jointly modified by 2-methylimidazole and zinc nitrate can effectively improve the mechanical property, the humidity resistance and the dirt resistance of the composition on cement. The applicant finds that the coordination load of the modified zinc oxide particles on the framework material forms composite particles with a heterojunction structure. The conduction band and the valence band of electrons in the framework material are lower than those of titanium dioxide, so that photon-generated carriers can circulate on the titanium dioxide and the framework material when being excited, electrons are gathered on the conduction band of the framework material and electron holes are gathered on the valence band of the titanium dioxide due to the positive and negative characteristics of the electrons and the electron holes, the electron-hole recombination phenomenon is not easy to occur, the forbidden band distance of the titanium dioxide is shortened, and the absorption performance of the titanium dioxide in the ultraviolet light and visible light double-band is effectively improved. And because the surface roughness of unit particles of the modified titanium dioxide nanoparticles is greatly increased, the surface energy is obviously reduced, and the titanium dioxide particles are changed from hydrophilic nanoparticles with 4 hydroxyl groups on the surface into hydrophobic nanoparticles, the waterproof and moisture absorption properties of the final cement finished product can be effectively improved.
Preferably, the auxiliary agent is at least one of a wetting agent, a dispersing agent, a surfactant, an antioxidant, an ultraviolet resistant agent, a water repellent agent and an anti-wear agent.
In a preferred embodiment, the dispersant is at least one of polyacrylamide, polyethylene glycol monostearate, cetyl trimethyl ammonium bromide and sodium lauryl sulfate.

as a preferable scheme, the organic amine is triisopropanolamine, tetrahydroxyethylethylenediamine, triethanolamine or tetrahydroxypropylethylenediamine; the mass ratio of the triisopropanolamine, the tetrahydroxyethyl ethylenediamine, the triethanolamine and the tetrahydroxypropyl ethylenediamine is (4-8): 1 to 3:5 to 11:2 to 4.
