Description
Technical field
The invention belongs to plugging material technical field more particularly to a kind of red mud base slip casting plugging materials.
Background technology
Red mud is the waste material of aluminum oxide industry production, and ingredient is extremely complex, generally often produces one ton of aluminium oxide and about produces 1-
1.3 tons of red muds.A large amount of red mud causes people's production and living direct or indirect influence, with the day of red mud quantum of output
The beneficial enhancing increased and people's environmental protection is realized, limits the harm of red mud to greatest extent, and utilization and improvement by all kinds of means is red
Mud is extremely urgent.
It is main problem that current China's coal-bed gas faces that it is too fast that coal bed gas extraction concentration is low, concentration value is decayed.Its
Reason except major part is poor by extraction gas permeability of coal seam, in addition to the agensis of crack, it is most important that sealing of hole is not tight, and sealing quality is paid no attention to
Think, the selection of sealing material is particularly critical, more demanding to air-tightness.
Patent of invention CN201510830990.6 discloses a kind of modified coal mine polyurethane plugging material, and air-tightness is very
Well but since plugging material belongs to high molecular material, expensive, it cannot be quoted extensively, and the present invention uses the materials such as red mud
Expect cheap.Patent of invention CN201710373800.1 discloses a kind of mining ickings base hole-sealing grouting material, although cost
It is more cheap, but sealing material intensity is relatively low, and only 2-3MPa is unable to get good application.Therefore, it is necessary to be directed to coal mine
The plugging material for the requirement exploitation function admirable that gas blocks.
Invention content
The present invention provides that a kind of air-tightness is good, and early strength meets micro-expansibility and price to solve above-mentioned technical problem
Cheap red mud base slip casting plugging material.
The purpose of the present invention is what is realized by following technical scheme：
A kind of red mud base slip casting plugging material, percentage, including following components：Red mud 20%-40%, fine coal
Grey 20%-40% and cement 20%-45%, it is 100% that the sum of said components, which add up,；The red mud base slip casting plugging material
Further include the expansion component that additional volume is 0.6%-9% and the rheology component that additional volume is 1.3%-6%；Wherein, institute
It includes swelling agent and antifoaming agent to state expansion component, and the rheological component includes water-reducing agent and silicon powder.
In said program, the cement includes portland cement 17%-35% and sulphate aluminium cement 3%-10%.
In said program, the volume of the water-reducing agent is 0.3%-1%, and the volume of the silicon powder is 1%-5%.
In said program, the volume of the swelling agent is 0.5%-1%, and the volume of the antifoaming agent is 0.1%-0.5%.
In said program, the expansion component further includes gypsum, and the volume of the gypsum is 2.5%-7.5%.
In said program, the gypsum is the mixed of one or more of anhydrite, the plaster of paris or dihydrate gypsum composition
Close object.
In said program, the unit weight of the red mud base slip casting plugging material is 900kg/m3-1200kg/m3。
In said program, the swelling agent is azodicarbonamide class swelling agent.
In said program, the antifoaming agent is polysiloxane defoaming agent, silicone emulsion antifoaming agent or high-carbon alcohol fatty acid ester
Compound antifoaming agent.
In said program, the water-reducing agent include polycarboxylic-acid or how based water reducer.
Red mud is aluminum oxide industry Bayer process red mud in red mud base slip casting plugging material provided by the invention.
The swelling agent that the present invention uses is a kind of flaxen azo type organic, and main component is azodicarbonamide,
What the present invention selected is such swelling agent of Pu Xin building materials Co., Ltd of Weifang City exploitation, such as HEA-GY models.This swelling agent energy
In cement hydration process, itself constantly decomposes and generate nitrogen to reach expansion effect and nitrogen is produced compared to swelling agents such as aluminium powders
Raw hydrogen is more advantageous to be used safely in gas environment.Existence of the bubble in slurry is similar to air-entraining concrete,
The endurance quality such as resist drying shrinkage of material, anti-carbonation properties etc. can be improved.Because in slurry the presence of bubble with
The fineness of material and the tension of slurry have relationship, so the fineness of red mud can limit the Air Bubble Size and spacing of swelling agent generation
Coefficient, water-reducing agent change the surface tension of slurry, also can preferably regulate and control bubble regime in slurry.Antifoaming agent can also be with expansion
Agent interacts, and removes larger bubbles extra in slurry, leaves behind miniature harmless bubble.
The present invention is based on the principle of alkali-activated carbonatite, the calcium hydroxide that highly basic and hydrated cementitious in red mud provide is made full use of to swash
SiO in hair powder coal ash2And Al2O3, hydrated calcium silicate and drated calcium aluminate are produced, early powerful feature is generated.Red mud has preferable
Water holding bleed performance, the moisture content in slip casting plugging material can be retained, greatly reduce later stage cement self-constriction drying receive
Contracting phenomenon.Red mud itself will not be shunk after drying dehydration.
The interaction of silicon powder and water-reducing agent makes the lubricating action of silicon powder embody out, can enhance slip casting envelope
The fluidity of stifled material, improves sealed borehole length.Silicon powder has also filled up plugging material hole, is formed with hydrolysis product of cement solidifying
Glue enhances plugging material intensity.
The present invention also provides a kind of application methods of red mud base slip casting plugging material：According to said ratio, by silicate
Cement, sulphate aluminium cement, red mud, flyash, expansion component and rheology component uniformly mix, according still further to ratio of water to material 0.6-
0.75：1 ratio calculates water consumption, and water is added uniformly to mix.
Compared with prior art, technical solution provided by the invention has following advantageous effect；
1) present invention uses aluminum oxide industry waste material, and raw material is easy to get, of low cost.
2) the slip casting plugging material intensity that the present invention obtains is high：3d can reach 6MPa, can reach 10MPa within 28 days.
3) the obtained slip casting plugging material good fluidity of the present invention, initial flux degree is up to 340mm, fluidity after 30min
>=260mm, the slip casting plugging material leakproofness that the present invention obtains is good, air permeability coefficient≤2 × 10-8m2。
4) present invention has early strong, high-strength feature.
5) slip casting plugging material of the present invention has microdilatancy, later stage shrinkage-free feature.
