Description
Technical field
The present invention relates to a kind of crack repairing agent, more particularly to a kind of crack repairing agent of Prestressed concrete cylinder pipe.
Background technology
At present, PCCP（Pre-stress steel cylinder）Pipe of concrete forms spiral due to liner steel cylinder automatic soldering technique reason
Gap is welded on steel cylinder surface, the induced cracking structure to the concrete cover of steel cylinder is produced, causes concrete to be supported in steam
Occurs the crack that 0.1~0.5mm is not waited after shield, the problems such as causing concrete quality difference and bad order produces to PCCP pipes and looked forward to
Industry causes very big puzzlement.
The solution used at present is mainly the patching material of inorganic patching material or high score subclass.Inorganic material is main
Based on cement mortar, although ensure that fusion between inorganic material and to the aqueduct water nonpollution of particular/special requirement will
Ask, otherwise intensity is often very low, or be exactly after repairing appearance it is very poor, it is difficult to reach that intensity is high and the good effect of outward appearance simultaneously
Really two requirements.And the cost of the patching material of high score subclass is high, poor durability, such as modified epoxy class contain more volatile
Property solvent composition, the easy act under moist and water environment do not significantly improve, easy hollowing, peeling.
Inorganic patching material of the prior art such as Publication No. CN104478371A, a kind of entitled " energy-saving coagulation
The patent of invention of soil cracking seam healant ", healant disclosed in the patent includes 12~18 parts of sand；5~10 parts of silica flour；It is general
Logical 20~35 parts of portland cement；10~18 parts of sulphate aluminium cement；6~12 parts of waterglass；Polyvinyl acetate emulsion powder
5~9 parts；3~7 parts of silica flour；7~10 parts of slag powders；6~9 parts of flyash；8~10 parts of swelling agent；Polycarboxylic acids high efficiency subtracts
0.4~0.6 part of aqua；0.2~0.4 part of polypropylene fibre.After portland cement and the sulphate aluminium cement mixing of the patent
Performance it is unstable, the unstable of whole repairing body is likely to result in, polypropylene fibre belongs to high-molecular organic material in addition, defeated
It may be ground off in waterpipe by punching and be directly entered water source, polluted, and its length is 9mm, is not suitable for 1~3mm of PCCP pipes
The repairing in crack；The healant is not adjusted for color, it is impossible to its overall appearance is reached consistent effect.The repairing
The intensity of agent and the Strength mis match of C50 PCCP pipes conventional at present, can be adversely affected for later stage durability.
The content of the invention
Present invention seek to address that inorganic crack repairing agent can not meet that intensity is high and outward appearance is good asks simultaneously in the prior art
Topic, and the cost of high score subclass patching material are high, the problem of application property is bad, propose that a kind of Prestressed concrete cylinder pipe is used
Crack repairing agent, healant of the invention can repairing concrete crack, meet the comprehensive physical performance of PCCP concrete ducts
And its durability is improved, make concrete surface color and luster consistent, lift presentation quality；The healant of the present invention produces for environmental protection simultaneously
Product, it is environmentally safe, on water quality without influence；And it is easy to construction, ensure construction quality.
In order to realize foregoing invention purpose, technical scheme is as follows：
A kind of crack repairing agent of Prestressed concrete cylinder pipe, it is characterised in that：Including following original by weight
Material：
25~60 parts of portland cement；
5~10 parts of active filler；
0.1~0.2 part of water reducer；
35~65 parts of tinting dye.
Preferably, the portland cement is portland cement 42.5, portland cement 52.5 and portland cement P.I
In one kind, intensity height, good endurance consistent with matrix at crack after repairing to ensure.
The effect of water reducer is reduction repairing slurry mixing water amount, it is ensured that healant has preferable workability, and
Can a certain degree of intensity for improving healant；Water reducer of the present invention is preferably High-efficiency polycarboxylic acid salt powder, naphthalene system hydrochlorate
One kind in powder, the wide material sources of both water reducers, application are wide, with adaptability is good, water-reducing rate is high, stability good
Advantage.
The effect of tinting dye is the addition of tinting dye, can improve the color of whole slurry, make its harden after with coagulation
Native surface color is consistent, obtains preferable presentation quality；The tinting dye is preferably quick lime, silica flour and agstone
Mixture, these three materials are inorganic mineral, and the compatibility with cement is good, are readily available stable slurry, and volume scope
It is easily controlled in width, production.
Further preferably, 40~80%, stone are accounted for for quick lime in the mixture of the quick lime, silica flour and agstone
English powder accounts for 5~50%；Agstone accounts for 5~20%.
Quartzy meal component is silica, with certain activity, equally can generate aquation silicon with calcium hydroxide reaction
Sour calcium, improves intensity, reduces evil material；Quick lime acts not only as adjusting the main material of color, meeting after it reacts with water
Heat is released, the performance of cement early strength is more beneficial for；Agstone is the important raw and processed materials of calcining cement, cheap,
Agstone can equally fill space, improve compactness, but more effects are regulation colors, improve the outward appearance one after repairing
Cause property.It is that quick lime accounts for 40~80% by special ratios, silica flour accounts for 5~50%；Agstone accounts for 5%~20% setting, can
After the healant repairing for ensureing the present invention, strength consistency and outward appearance uniformity good advantage are provided simultaneously with.
Active filler effectively can starch internal void by filling concrete, and active filler of the present invention is preferably nanometer titanium dioxide
One kind in silicon, slag powders, the nano silicon that nano silicon selection average grain diameter is 20~100nm；Slag powders are selected
Select specific surface area >=500m2/Kg slag powders；Two kinds of active fillers can not only fill space, moreover it is possible to carry out secondary hydration, consumption
The calcium hydroxide produced in cement hydration process, and the calcium hydroxide that quick lime is produced, generate hydrated calcium silicate, reduce product
In harmful substance contents, improve durability, promote cement mortar stable long-term strength to increase.
Compared to prior art, beneficial effects of the present invention are as follows：
（1）The crack repairing agent of the present invention is selected and specific proportion design by raw material, is capable of mending concrete
Crack, meets the comprehensive physical performance of PCCP concrete ducts, and improves mend and pipe fitting after the durability of mend, repairing
Strength consistency it is good, appearance looks elegant is and environmentally safe without substantially repairing vestige.
（2）It is about 20MPa that current PCCP pipes support demoulding strength after steaming, and ground on the scene is dispatched from the factory after placing 8~24 hours, is originally repaiied
Tonic is constructed in after the pipe demoulding, and 8 hours intensity levels can reach 15Mpa, and intensity level can reach within 24 hours
30MPa, is consistent substantially with matrix strength, it is ensured that the uniformity of body intensity.Unanimously reduction can body inner concrete for intensity
Internal stress effect, it is ensured that the integrality of later stage body, intensity particularly important for the water delivery engineering containing sand such as the Northwest
It is inconsistent, wear extent difference is easily caused, " cavitation corrosion " will be formed, unstable wear accelerates the failure, and reduce durability；The present invention's
Healant is while quality is ensured, outward appearance uniformity is also good, while improving product appearance quality, improves the competition of product
Power, so as to improve the economic benefit of enterprise.
