Abstract
A pumping cement mixture for filling and reinforcing wall rock in well. The mixed material adopts the sulphoaluminate cement (or cement clinker) sintered by low-grade bauxite as a base material to replace most or all of high-alumina cement required in the original preparation process, so that the cost of raw materials is greatly reduced, the source of the raw materials is increased, and the preparation process is simple, easy to operate and good in strength performance. At the same time, industrial waste ash can be added to reduce the cement consumption and raw material cost and solve the problem of environmental pollution.
Description
A kind of novel cement additive that is suitable for pumping is mainly used in underground filling and grouting reinforcement rock.Comprise the tunnel, roadside packing, excavation support support with backfilling, the filling of inbreak hole, pit shaft support with backfilling, are constructed anti-fire extinguishing partition wall and surrounding rock consolidation etc. at the filling that need carry out because of mining effect.
About the research of filler, Britain is the most representative, has developed low water filler and high water filling material once.Low water filler is few because of adding the water yield, and suitable wind-force is carried; The high-water material amount of water is many, and suitable waterpower is carried (pumping).The low water filler that they work out mainly adopts normal portland cement, add accelerating admixture or curing compound, as gathering materials formation, its major defect is that early strength is on the low side with gangue fragment, flyash, coal dust, amount of water is few, and water volume generally only accounts for below 55% of cumulative volume.When amount of water increased, the strength of materials descended rapidly and is difficult to and solidifies, thereby strict control amount of water.The high water filling material that Britain research goes out has Aquapack material (patent No. GB2033367A, GB2058037A), Tekpack material (patent No. GB2123808A), TekpackXX, HydropacK material etc., what use in a large number at present is that the TekpackXX.Aquapack material is base material with portland cement, add high alumina cement (being mainly the calcium aluminate composition) and mix with calcium sulfate, this material usage is 500kg/m
3The time, water consumption is 800～860kg/m
3; Tekpack material and TekpackXX are base material with the high alumina cement, add calcium sulfate and calcium oxide or calcium hydroxide and mix, and this material usage is 364kg/m
3The time, water consumption is 910～920kg/m
3; The Hydropack material then (contains calcium sulphoaluminate 3CaO3Al with a kind of special cement

3Two kinds of main components) being base material, adding calcium sulfate and calcium oxide or calcium hydroxide and mix, is 350kg/m at material usage
3The time, water consumption is 920kg/m
3.Aguapack, contain more calcium aluminate component among the Tekpack, TekpackXX material requirements high alumina cement, and they are the same with the Hydropack material, require inertia gehlenite 2CaOAl
2O
3SiO
2Content is extremely low, thereby very high to burning till the required bauxite grade requirement of cement, and raw material, fuel, firing process require very tight, have increased material cost, and raw material sources wide, be unfavorable for promoting.In addition Aguapack, TekpacK, TekpackXX material mixture ratio not at that time, the Ca(OH that produces in the hydration process)
2High alumina cement wink is coagulated, have a strong impact on the intensity of material, so these two kinds of material requirements batchings are strict, to the mineralogical composition content requirement strictness of each component.
In view of the existing all deficiencies of existing various fillers, the objective of the invention is to study that a kind of raw material source is wide, cost is low, easily make and operate and strength character good, be specially adapted to the suitable pumping filling and the injecting paste material of underground filling and surrounding rock consolidation.
Filling and injecting paste material that the sulphate aluminium cement (or clinker) that the present invention adopts low-grade bauxite to burn till is studied as base material have overcome the various deficiencies of original various fillers.The present invention is by adjusting the Al in the entringite generation slurries

3Concentration generates entringite to greatest extent before reaching the condensation of materials sclerosis, the sclerosis back generates small amount of calcium aluminite.By improving β-2CaOSiO

2O etc. are therebetween mineral-filled, make the material internal structure closely knit and improve intensity.The shared volume ratio of water reaches more than 60% in this material, suitable pumping.Can use slag stock pump (containing slush pump, mortar pump) to carry.This kind filler comprises following various composition:
1. each component of cement admixture and content ratio
(1). sulphate aluminium cement (or clinker).Comprise aluminium sulfate high-early (strength) cement, aluminium sulfate expansive cement, aluminium sulfate self-stressing cement.
(2). ordinary Portland cement or aluminate cement.Wherein ordinary Portland cement comprises Portland cement, portland slag cement, portland cement, Portland fly ash cement, sulfuric-resisting portland cement.Aluminate cement comprises high alumina cement, aluminate expansive cement, aluminate self-stressing cement, gypsum aluminate expansive cement.The dosage of ordinary Portland cement or aluminate cement accounts for 5～100% of sulphate aluminium cement (or clinker) weight.
(3). calcium sulfate.Can adopt a kind of or wherein several mixed gypsum of semi-hydrated gypsum, dihydrate gypsum, hard burnt plaster to provide.Its dosage accounts for 2～40% of sulphate aluminium cement (or clinker) weight.
(4). calcium oxide or calcium hydroxide.Employing lime gets final product, and its dosage accounts for 0～30% of sulphate aluminium cement (or clinker) weight.
2. suspending agent.Adopt clay or swell soil, its dosage is 0.1～15% of a cement admixture gross weight
3. inorganic salts and hydroxide accelerating admixture.The one or more combination of available sulfate, nitrate, carbonate, halide or hydroxide, its dosage accounts for 0～15% of cement admixture gross weight.
4. organic matter retarding agent.The one or more combination that comprises carboxylic acid, hydroxycarboxylic acid and its esters, silicofluoride adds the pump time that it can improve material.Its dosage accounts for 0～3% of cement admixture gross weight.
5. industrial waste lime-ash.The slag that comprises fly ash in electric power plant, fluidized bed furnace lime-ash, the logical ash of cigarette, gangue and other kinds.Its dosage accounts for 0～300% of cement admixture gross weight.
The present invention is owing to use sulphate aluminium cement (or clinker) to replace original required most of or whole aluminate cement of technology of making, can also add the industrial waste lime-ash, significantly reduced cost, and made that technology is simple, the raw material source is wide, easy to operate, strength character is good.Utilize lime-ash can also solve problem of environmental pollution.In addition, when this material slurry does not mix with accelerating admixture, do not add retarding agent, but the pump time can reach more than 4 hours, prolonged several times than other materials, fed distance has extended.
