Description
Technical field
The invention belongs to strength cement-based grouting material field, and in particular to filled to a kind of cement base with chlorion hypotonicity
Slurry.
Background technology
Strength cement-based grouting material is by cement, additive（Water reducer, swelling agent, retarder etc.）, gather materials and mineral admixture
Deng the dry blend that material is bound together, adding water has the advantages that intensity high, Workable, not microdilatancy, bleeding after mixing and stirring, and
Such grouting material is nontoxic, cheap, is applied to the anchoring of the back-grouting, foundation bolt of mechanical equipment installation more, mixes
Xtah Crude Clay structure is transformed and the field such as is connected with reinforcing, the grouting of assembled architecture.
As coastal economy develops on a large scale, high-rise building and Large-Scale Equipment emerge in an endless stream, especially the Sheng of assembled architecture
OK, but these buildings or the equipment long-term seepage failure by chlorion in use, building or equipment are shortened
Service life, and the resistance of chloride ion penetration of strength cement-based grouting material of the prior art is low, therefore coastal engineering pair can not be met
The requirement of basic material.
The content of the invention
A kind of defect it is an object of the invention to overcome prior art, there is provided cement base suitable for chlorion hyposmosis
Grouting material, except having the advantages that early strength is high, later strength is high, Workable, microdilatancy, not in addition to bleeding, also with total chlorine
Ion concentration is low, electric flux value is low, the characteristics of resistance of chloride ion penetration is high.
To achieve the above object, the present invention proposes following technical scheme：A kind of cement base suitable for chlorion hyposmosis
Grouting material, is constituted and mass percent with following material：
42.5R Portland cements： 39.7%~40.7%；
River sand： 39.7%~40.7%；
Flyash： 3.2%~3.3%
Silicon ash： 2%；
Water reducer： 0.28%；
Retarder： 0.04%；
Swelling agent： 3.18%~3.28%；
Water： 9.7%~11.9%.
Preferably, the portland cement density is 3.21g/cm3, specific surface area is 355m2/ kg, fineness is 0.85%,
Consumptive use of water normal consistence 31%, alkali content 0.67%, loss on ignition 4.11%, volume stability and pressure-proof and snap-resistent intensity are qualified.
Preferably, the flyash is I grade of flyash, density 2.78g/cm3, water demand ratio 93.5%, loss on ignition
2.7%, 45 μm of screen over-sizes 4.47%.
Preferably, described silicon ash is SILICA FUME.
Preferably, the river sand is washed more than 20 times and dries dry, particle diameter≤2.36mm, modulus of fineness Mf=in advance
2.78。
Preferably, the water reducer is Polycarboxylic Superplasticizer, diminishing efficiency is 25%；
Preferably, described retarder is tartaric acid.
Preferably, described swelling agent is CMA high performance expansion admixtures.
The present invention provide chlorion hyposmosis strength cement-based grouting material in, flyash improve grouting material microstructure and
The composition of hydrated product, reduces transmittability of the chlorion in the middle of grouting material, improves the chloride-penetration resistance of grouting material
Performance, additionally, flyash has preferable water-retaining property, can improve the intensity and workability of grouting material；Silicon ash is preferably filled out
The space of cement particle is filled, increases the mobility of grouting material, while improving the packing and intensity of grouting material；River sand maximum particle diameter
2.36mm, had both met the requirement of fluidity, and the intensity of grouting material is can ensure that again；High efficiency water reducing agent effectively reduces the ratio of mud, reduces
The quantity and size of macropore, improve the Anti-Chloride Ion Penetration of hardened paste；The hydration rate and water of retarder reduction cement
The mud heat of hydration, reduces the gradual loss of grouting material fluidity；Swelling agent is filled out by the secondary hydration with hydrolysis product of cement
Fill, cut off big continuous pore, increased the packing of grouting material, improve its resistance of concrete to chloride ion penetration, further, since
Swell increment is more than aquation amount of contraction, and the anti-crack ability of grouting material is improved, it is ensured that its good anti-permeability performance.
Compared with prior art, a kind of strength cement-based grouting material suitable for chlorion hyposmosis that the present invention is disclosed, uses
Common low-grade cement, it is cheap, using extensive；The strength cement-based grouting material of chlorion hyposmosis prepared by the present invention is removed to be had
Early strength is high, later strength is high, Workable, microdilatancy, not bleeding the advantages of outside, also with total chloridion content is low, electricity
Amount of flux is low, the characteristics of resistance of chloride ion penetration is high, can be widely applied to the back-grouting of mechanical equipment installation, foundation bolt
Anchoring, concrete structure transformation the field such as are connected with reinforcing, the grouting of assembled architecture, especially meet coastal engineering to basis
The requirement of property material.
