The early strength agent is prepared by mixing 50-60% of iron tailings, 30-40% of carbide slag and 10-15% of coal gangue, carrying out static pressure molding, placing the mixture in a kiln with a ventilation facility, heating the mixture to 750-850 ℃ at a constant temperature of 10 ℃/min, taking out and naturally cooling the mixture, wherein the coal gangue is the coal gangue subjected to vector burning treatment, and the coal gangue subjected to vector burning treatment can discharge vulcanized gas, so that the problem of incomplete reaction caused by cracking in the firing process of the early strength agent is avoided.
C in the Portland cement clinker 3 The S content is 70-85%, the gypsum is natural dihydrate gypsum, the water reducer is a polycarboxylate water reducer, and the dispersing agent is citric acid.
The iron tailings are residues left after iron ore is subjected to magnetic separation to obtain iron ore fine powder, and the residues are rich in chemical compositions such as ferric oxide, silicon dioxide, aluminum oxide, calcium oxide, sodium oxide and the like.
The calcium carbide slag is waste slag which takes calcium hydroxide as a main component after calcium carbide is hydrolyzed to obtain acetylene gas, has the solid content of 12.0 percent, belongs to national class II industrial solid waste, and is directly used as an adhesive for static pressure molding because of the high calcium content to provide calcium on one hand and the high water content on the other hand.

The particles can no longer be arranged according to a certain rule to form a structure in a thermodynamically unstable state.
The invention also aims to provide a preparation method of the high-performance self-leveling cement, which comprises the steps of placing silicate cement clinker, water quenching blast furnace granulated slag, an early strength agent and high collar soil into a cement mill for grinding until the specific surface area is more than 450m 2 And (3) adding the water reducer and the dispersing agent into a cement mill, and obtaining the high-performance self-leveling cement from the mixed material from the head of the cement mill.

1. the early strength agent is realized by the modified gehlenite generated in a sintering system, the hydration reaction is rapid, and the structure of a hydration product is compact, so that the system has the advantage of high early strength;
2. according to the early strength agent, the iron tailings are used as a main body, the carbide slag is used as an alkali activator, the coal gangue is used as a dry system to add Mg element, and the modified geilite is generated through an activation reaction;
3. the early strength agent raw material system contains a large amount of iron phases and Mg elements, so that the viscosity of a liquid phase can be reduced, silicate phases can be generated in advance, the calcination temperature of clinker of the system is low, and the emission of greenhouse gases can be greatly reduced;
4. the invention adopts water quenching blast furnace granulated slag, iron tailings, carbide slag, coal gangue and high collar soil to replace cement clinker, thereby achieving the purposes of protecting environment, saving resources and developing low-carbon economy; the cement clinker has low carbon, early strength, rapid hardening and continuous increase of later strength, greatly reduces the mixing proportion of the cement clinker in the high-performance self-leveling cement, and has obvious economic effect;
5. the mortar slurry structure prepared by the high-performance self-leveling cement has good suspension property, high fluidity, no layering, no bleeding, no segregation, high mortar strength, high bonding strength, good water retention and specific surface area of cement more than 450m 2 And the powder fineness is high, so that the strength of the cement is improved.
