It is long.
Blast-furnace cinder is made up of gangue, ash content, fluxing agent and other impurity that can not enter in the pig iron, is a kind of easy
It is fused and mixed compound.Chemically from the point of view of composition, blast-furnace cinder is to belong to phyllosilicate material.With the potential hydraulicity and potential work
Property, its yield is generally 25% or so of pig iron yield.
Desulfurated plaster is the accessory substance that thermal power plant uses Wet Flue Gas Desulfurization Technology.In recent years, as China is with wet method cigarette
Desulfurization vigorously implements popularization for mainstream technology, and the discharge capacity of its accessory substance desulfurized gesso of flue gas is growing day by day, long-term to stack
Cause stacking cost increase and environmental pollution.
Goaf, the barren rock stacked, spoil area and the tailings dam constructed that pit mining leaves large area bring serious
Place of safety hidden danger and carrying capacity of environment.Tailings Dam dam break, heavy metal pollution event emerge in an endless stream, such as Liuyang cadmium pollution event, Jiyuan
Lead contamination event, Fengxiang blood lead event and Zijin Mining seepage event etc., storing up for these hazardous wastes seriously threatens the mankind

Filling method typically use using rubble, river sand or tailings or Gobi aggregate as aggregate (or mix block stone), with cement or lime
Cementing material is transported to the filling of filling area with pipeline pumping or flow by gravity mode through mix formation slurry or lotion.Mine
The method of mining by the way of filling has high stoping rate, ore dilution rate low, effectively control ground pressure, prevents ground subsidence, protection mine environment etc.
Advantage.But process for stoping and filling process are more complicated, mining and filling influence each other, if stoping operation mechanization problem
It can not properly settle, then production efficiency and ability are relatively low, in addition casting resin exploitation, processing, conveying and a series of other consumings,
Therefore raw ore cost is higher.
Portland cement is the most frequently used cementing agent, but its production technology has high energy consumption in itself, with serious pollution
Feature.In recent years, a large amount of novel gelled materials of appearance, are essentially all the basis in Portland cement or slag cements
On be improved, even if with the replacing partial cement clinker such as slag, flyash, red mud with hyperpyrexia history, but due to former material
The limitation of material, substitution clinker quantity are low, cementing result it is undesirable in terms of restrict its popularization and application.Cemented filling material contains certain ratio
The cementing agent of example, with higher intensity and globality, with higher operational security, is meeting various underground support demands
While can improve the rate of extraction of ore and the operating efficiency of stope.With the popularization and application of filling in mine mining technique,
Cementing agent for filling is also constantly updating the replacement, and effective way is provided for large industrial solid castoff recycling.

The mechanism of action of the cementing agent is as follows：
Casting resin can obtain good intensity, and it is core cementing agent aquation therein is produced enough C-S-H gels
Problem.And to (SiO in the maximum C-S-H gels of casting resin intensity contribution2+Al2O3)/(CaO+MgO) mol ratio 0.6~
Within the scope of 0.8.Existing enough results of study show that the ratio in the range of this in C-S-H gels is higher, and its is right
The intensity contribution of casting resin is bigger.C-S-H gels are the chain columnar structure silicate being formed by connecting by silicon-oxy tetrahedron, and water quenching grain
Change (SiO in blast-furnace cinder2+Al2O3)/(CaO+MgO) mol ratio more than 0.9.
(SiO in slag2+Al2O3)/(CaO+MgO+FeO) ratio is very low, and generally below 0.15.If therefore slag is worn into
Micro mist, it is extremely weak that slag micro powder provides the tetrahedral ability of silicon (aluminium) oxygen for the gel hardening of casting resin and gain in strength.In C-S-H
In gel, not only a large amount of silicon-oxy tetrahedrons can be replaced by aluminum-oxygen tetrahedron and a certain amount of iron oxygen tetrahedron, and therein
Calcium ion can be replaced by divalent ions such as substantial amounts of magnesium ion, ferrous ions.Therefore, if can be thin into micron order by steel slag grinding
Powder, can comparatively fast occur hydration reaction, and substantial amounts of divalent metal just can be provided for gelling system.
The content of aluminum oxide is general higher in granulated blast-furnace slag, and with alumina four sides in the vitreum of blast-furnace cinder
Body form is linked with silicon-oxy tetrahedron.When the higher ph solution that blast-furnace cinder and slag are formed is contacted, aluminum-oxygen tetrahedron
Tend to the depolymerization from the link of silicon-oxy tetrahedron and enter solution.In the presence of having more gypsum in system, can quickly occur calcium
The crystallization reaction of aluminite.
4H3AlO4 2-+6Ca2++6CaSO4·2H2O+4OH-+44H2O→2(3CaO·Al2O3·3CaSO4·32H2O)
Entringite is a solubility very low double salt.C.B.Satish etc. is in Chemical Geology, (148)
1998, the entringite solubility product constant reported in the 1-19 pages is 10-111.6.It, which is constantly crystallized, causes Al in solution3+Ion is dense
The reduction of degree, makes the balance of above-mentioned reaction equation move right, and reaction is constantly carried out.Al3+A large amount of dissolutions of ion make granulated blast-furnace
Aluminum-oxygen tetrahedron in slag micropowder links disconnection with silicon-oxy tetrahedron, and remaining silicon-oxy tetrahedron activity is significantly carried
Height, so as to constantly produce the tetrahedral depolymerization of silicon (aluminium) oxygen, the generation to a large amount of C-S-H gels creates condition.
The generation of a large amount of C-S-H gels not only needs silicon (aluminium) oxygen of a large amount of activity on four sides, and need substantial amounts of calcium,
The bivalent cations such as magnesium, iron.And the aquation of slag can effectively provide these divalent metals.Therefore wear into micron-sized
Superfine steel slag micropowder acts synergistically with blast furnace slag micro mist, desulfurated plaster micro mist, can be made into the filling in mine for substituting cement
Use cementing agent.
