Description
Technical field
The present invention relates to building material technical field, a kind of aqueous infiltrating type concrete dense curing agent.
Background technology
Concrete, as a kind of widely used construction material, plays great function in modern construction engineering.But,
Normal concrete is rolled over due to intrinsic deficiency, the bad or chemical attacks of constructing, fork truck in-service as earth material
Pressure etc., cause whole ground produce Coarse Aggregate scatter and disappear, pit-hole, peeling or the phenomenon such as loose.For avoiding these phenomenons to occur, generally
Pour the materials such as epoxy resin at concrete surface, the most both added construction cost, also improve later maintenance expense.
Occur in that concrete curing agent reaches with the density and case hardness improving xoncrete structure in recent years on market
To improving concrete floor effect.At present, concrete dense curing agent mainly has two classes: a class is using resin as main component
Organic polymer class, another kind of is the mineral-type with silicate as main component.Wherein mineral-type can be easily made water-based material,
Without volatile organic matter, the impact on environment is little, and can receive much concern with hydrolysis product of cement chemically reactive.
Existing mattess intensity and wearability is the highest, rise ash dusting problem generally exist, developing can be effective
Improve mattess abrasion resistance, avoid it to play ash dusting, improve the curing sealing agent of its impervious resistance to soiling, there is important valency
Value and meaning.
Summary of the invention
It is an object of the invention to the defect for prior art, it is provided that one can be suitably used for poor mattess, can make
Obtain high intensity, the aqueous infiltrating type concrete dense curing agent of high abrasion mattess.
A kind of aqueous infiltrating type concrete dense curing agent, the percentage by weight of its each component is as follows:
Further, aqueous infiltrating type concrete dense curing agent, the percentage by weight of its each component is as follows:
Described silicate is one or more in sodium silicate, potassium silicate and Lithium metasilicate.
Described penetrating agent be the one in dodecyl sodium sulfate, alkylphenol polyoxyethylene or fluorocarbon surfactant or
Several.
Described accelerator is in lignosulfonates, naphthalene sulfonate, melamine, polycarboxylate, villaumite, sulfate, organic amine
One or more.
Described waterproofing agent is in octyltri-ethoxysilane, octyltri-ethoxysilane aqueous emulsion, methyl silicate
Plant or several.
The advantage of aqueous infiltrating type concrete dense curing agent of the present invention is: can be watered according to concrete substrate situation and make
With, spraying or be brushed to concrete structural surface, active component therein penetrates into inside concrete by the effect of accelerator
2-8 millimeters deep, and react formation afwillite (C-S-H) gel with the calcium hydroxide crystals in concrete, thus fill out
Fill and closed concrete pore, the intensity of mattess, abrasion resistance are significantly increased, it is to avoid ash dusting is played on ground, and
It is obviously improved the impervious resistance to soiling on ground.
Detailed description of the invention
Elaborating embodiments of the invention below, the present embodiment carries out reality premised on technical solution of the present invention
Execute.
Present pre-ferred embodiments discloses a kind of aqueous infiltrating type concrete dense curing agent, this concrete sealing and curing

And the water of surplus.
Described silicate can select one or more to mix from sodium silicate, potassium silicate and Lithium metasilicate.Wherein, resultant effect
And economic aspect considers, sodium silicate and potassium silicate the raising mattess that surface is rougher, dusting is more serious intensity and
Wearability aspect has advantage, and Lithium metasilicate price is higher, considers according to consumption, is more suitable for basis preferably mattess.Should
It is 75%-95%, preferably 85-90wt% that silicate content accounts for percentage by weight.
Described penetrating agent promotes concrete dense curing agent to permeate to inside concrete.Penetrating agent is dissolved in firming agent, makes
Effective ingredient stably dispersing in firming agent, promotes that the liquid film formed permeates in concrete, accelerates and calcium hydroxide, aluminate hydrates
The reaction of calcium etc., forms gel hard, that cohesive is good, and fully blocking concrete pore, makes concrete surface layer be solidified into one
Individual dustless, fine and close entirety.This penetrating agent can be dodecyl sodium sulfate, alkylphenol polyoxyethylene or fluorocarbon surfactant
In one or more be combined.By the stably dispersing effect of penetrating agent, active ion such as silicic acid contained in aqueous hardening dose
Unreacted free ion such as calcium ion reacts generation calcium silicate hydrate to radical ion with concrete, makes in concrete free
State ion participates in reaction, and intensity and the hardness of concrete are significantly increased.It is 0.1-that this penetrating agent content accounts for percentage by weight
1.5wt%, preferably 0.5-1.0wt%.
The hard water resistance property of described accelerator is preferable, can excite activity micro crystal in concrete, prevents activity micro crystal
Between cohesion and conglomeration, make activity micro crystal fully dispersed, thus activity can give full play to, and accelerates calcium silicate hydrate gel
Generation.Concrete active micro crystal includes the tricalcium aluminate in the materials such as slag, zeolite powder, flyash, silica flour, ferrum aluminic acid
One or more of four calcium, aluminium oxide, entringite etc. are combined.Described accelerator can be lignosulfonates, naphthalene sulfonate, close
One or more in amine, polycarboxylate, villaumite, sulfate, organic amine are combined.This accelerator content accounts for percentage by weight
0.1-1.0wt%, preferably 0.5-0.8wt%.
