Abstract

A kind of not disperse contraction-free grouting concrete under water, the composition of raw materials of the slurry is made up of the water of 60 65% portland cement, 5 8% aluminate cement, 5 7% desulfurated plaster, 2 3% extra light calcined magnesia swelling agent, 2 3% middle activated magnesia swelling agent, 0.1~0.3% polycarboxylate water-reducer, 0.02 0.05% triethanolamine, 1 2% alum, 0.05 0.08% polyacrylamide, 0.05 0.08% SYNPERONIC PE/F68 and surplus.The slurry of the present invention has good mobility and concrete castability, and direct grouting construction does not disperse, do not isolated under water, and hardened paste early stage and later strength are all good, and slurry has higher volume stability, and ungauged regions, durability has clear improvement.

Description

It is a kind of not disperse contraction-free grouting concrete under water
Technical field
Do not disperse contraction-free grouting concrete under water the present invention relates to a kind of, belong to new material technology field.
Background technology
Contraction-free grouting concrete be one kind using cement-based gelling material as base material, with the additive and fine aggregate etc. such as super plasticizer The grouting patching material mixed, with large fluidity, early strong, high-strength, microdilatancy performance.It is usually used in drying shrinkage to compensate, early By force, high-strength grouting, repairing, form high-strength, fine and close, impervious hardenite.It can be used between filling hole, basic unit and bottom plate and rise Supporting role, such as column beam joint, bridge pad, equipment support, crane runway, also can be used as bolt, bar splicing, bearing etc. Fixation.
For grouting material, it would be highly desirable to which solution is early strong and the problem of expansion, also large fluidity and resisting under water disperses The contradictory problems of property.For these problems, following several processing approach have been formd at present：One is in Portland cement Plus early strength agent and swelling agent, two be to use characteristic cement, and three be Portland cement and characteristic cementitious composite.These methods are all It there are problems that stability is poor, endurance quality.
The content of the invention
Do not disperse contraction-free grouting concrete under water it is an object of the present invention to provide a kind of.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of contraction-free grouting concrete not scattered under water, it is described The composition of raw materials of slurry is made up of the material of following masses percentage：
Portland cement 60-65%；
Aluminate cement 5-8%；
Desulfurated plaster 5-7%；
Extra light calcined magnesia swelling agent 2-3%；
Middle activated magnesia swelling agent 2-3%；
Polycarboxylate water-reducer 0.1 ~ 0.3%
Triethanolamine 0.02-0.05%；
Alum 1-2%；
Polyacrylamide 0.05-0.08%；
SYNPERONIC PE/F68 0.05-0.08%；
Water surplus.
It is preferred that technical scheme be：The portland cement is P.O.42.5 cement.
It is preferred that technical scheme be：The calcining heat of the extra light calcined magnesia swelling agent is 700 DEG C, and specific surface area is more than Or equal to 350 m2/Kg。
It is preferred that technical scheme be：The calcining heat of the middle activated magnesia swelling agent is 900 DEG C, and specific surface area is more than Or equal to 400 m2/Kg。
It is preferred that technical scheme be：The purity of the triethanolamine is more than or equal to 98%.
It is preferred that technical scheme be：The water-reducing rate of the polycarboxylate water-reducer is 25%.
It is preferred that technical scheme be：The mean molecule quantity of the polyacrylamide is 5,000,000.
It is preferred that technical scheme be：The molecular weight 1500-2000 of the SYNPERONIC PE/F68.
Because above-mentioned technical proposal is used, the present invention has following advantages and effect compared with prior art：
The present invention forms stable expansion sources in long life cycle using the magnesia calcined under gypsum and different temperatures（Calcium Aluminite-extra light calcined magnesia --- middle extra light calcined magnesia system）, triethanolamine is used in combination and alum auxiliary improves grouting material Early strength, utilize triethanolamine and polycarboxylate water-reducer polymolecularity and space steric effect lifted grouting material flowing Property, the dispersion resistance energy of slurry is improved using polyacrylamide and PEP-101.The slurry so prepared With good mobility and concrete castability, direct grouting construction is not scattered under water, do not isolate, and hardened paste early stage and later stage are strong Degree is all good, and slurry has higher volume stability, ungauged regions.Durability has clear improvement.
