Inventor additionally provides the preparation method of above-mentioned high-strength fast solidifying tailings cementitious matter, including following operating procedure:
Blast-furnace cinder, industrial waste gypsum, limestone are fully dried, is finely ground into powder respectively, then by modified gypsum, silicic acid
Salt cement is finely ground into powder, weighs each component, mix homogeneously.
Blast-furnace cinder is the industrial residue of discharge in blast furnace ironmaking production process, is melting with calcium silicates as essential mineral
Thing, is condensed into granular substance through shrend.Its chemical composition is mainly silicon dioxide, aluminium sesquioxide, calcium oxide, magnesium oxide, oxygen
Change manganese, ferrum oxide.Additionally, in some slag possibly together with the titanium oxide of trace, vanadium oxide, sodium oxide, Barium monoxide, phosphorous oxide, three
Aoxidize two chromium etc..In blast-furnace cinder, calcium oxide, silicon dioxide, the amount of aluminium oxide account for more than 90%, as cement, have potential
Hydration activity, and the size of activity is relevant with the vitreous body content that chemical composition and shrend produce, but it must be at some chemistry
Activity is just presented under the exciting of reagent.The present invention use composite additive to excite the activity of blast-furnace cinder, respond well.
In the preparation process of modified gypsum, the method for 800 DEG C of calcinings makes the crystallographic system in Gypsum Fibrosum be changed into orthorhombic by six sides
System, this rebuilding type that is changed into changes, and during transformation, chemical bond destroys, and the energy of needs is big, has therefore calcined temperature retention time and to have grown
Some, need 2-3 hour；The method of 400 DEG C of calcinings makes the crystallographic system in Gypsum Fibrosum be become hexagonal crystal system from three-party forwarding, is height right
Title type changes, and this is changed into displacement transformation, and during transformation, chemical bond is not destroyed, and simply bond angle changes, the energy of needs
Measure little crystal conversion rapid, therefore calcined temperature retention time and need not oversize, one hour.
The present invention uses blast-furnace cinder to produce Binder Materials, reduces the production cost of enterprise, protects environment simultaneously, joint
About mineral resources, can produce significant economic benefit and social benefit.High-strength fast solidifying tailings cementitious matter of the present invention is every
Performance indications all can meet underground mining needs, is particularly suited for iron mine underground filling.Have compared with agent solid with other tailings glue
Strength of filling mass is higher, and especially early strength is high, and stable long-term strength develops, and the feature that water stability is good, especially can
Gather materials on the spot, mass efficient utilize endemicity material, can make construction costs decline 20-30%, strength of filling mass require identical
Under conditions of, high-strength fast solidifying tailings cementitious matter usage amount of the present invention only needs the half of ordinary cement or less, can make filling
Cementing agent cost declines more than 7%, economic benefits.
High-strength fast solidifying tailings cementitious matter of the present invention also has feature highlighted below, and the curable general soil body, including sand mold
Soil, meets and uses tailing filling to require to reach mining technology desirable strength, and mine uses tailing filling, iron ore comprehensively
The rate of extraction reaches more than 90%, and rock stratum, exploiting field is effectively supported, and has carried out huge safety guarantee to back production work strip.
