Abstract
The present invention relates to a kind of nanometer base cement modifier, this modifying agent is prepared by after the raw material mix homogeneously of following mass parts: modified lignin sulfonate 3 ~ 6 parts, nano powder 65 ~ 85 parts, complex slag 10 ~ 20 parts.The present invention is with low cost, and modified effect is good, it is adaptable in the common portland cement of all kinds of specifications and models of non-retardation setting type.
Description
Technical field
The present invention relates to a kind of cement modifier, particularly relate to a kind of nanometer base cement modifier.
Background technology
At northern China cold district and salinization of soil area, the freeze injury of concrete structure, Cl-And SO4 2-Radical ion etch
The most more serious, consequently, it is possible to cause a series of diseases such as the seepage of concrete works, cracking, reduce its durability and safety.
Therefore, how imperative from main material Binder Materials this difficult problem of solution of starting with.In addition nano powder is ultra tiny calcium powder dirt, and surpasses
Fine calcium powder dirt be the raw material dust and high-temperature region intense reaction carried out in blast furnace ironmaking process along with coal gas and produce micro-
Particle diameter dry method dust and the product that obtains, this product is at present in the urgent need to effectively processing the industrial waste of recycling, if too late
Time process, do not only take up a large amount of place, and pollute the environment.
Summary of the invention
The technical problem to be solved is to provide a kind of energy with low cost, final, and effective to improve concrete resistance to
The nanometer base cement modifier of property for a long time.
For solving the problems referred to above, a kind of nanometer base cement modifier of the present invention, it is characterised in that: this modifying agent by
Prepare after the raw material mix homogeneously of following mass parts: modified lignin sulfonate 3 ~ 6 parts, nano powder 65 ~ 85 parts, complex slag 10
~ 20 parts.
Described modified lignin sulfonate refers to MODIFIED LIGNOSULPHONATE, modified sodium lignosulfonate, modified lignin resin sulphur
Being combined of one or more in acid magnesium, modified lignin resin ichthyodin.
Described nano powder refers to ultra tiny calcium powder dirt, and this ultra tiny calcium powder dirt refers in blast furnace ironmaking process along with coal gas
The raw material dust and the high-temperature region intense reaction that carry out and product that the microgranule produced obtains through dry method dust.
Described complex slag refers to that limestone is mixed by any ratio, through fineness 400 obtained by grinding after activating with slag powders
Purpose powder.
The present invention compared with prior art has the advantage that
1, the super nano powder in the present invention (ultra tiny calcium powder dirt) belongs to dedusting product, has a characteristic that (1) particle diameter is extremely
Small, density is little, easily flies away pollution environment in air；The most easily reacting, activity is good；(3) there is certain chemical toxicity.Exploitation
Comprehensive utilization to it is possible not only to make the resource of preciousness be fully used, it is also possible to alleviate the pollution to environment.And use
Cement solidification easily float noxious substance be the most all considered the most at present, the safest, most effective
Measure.
2, the ultra tiny calcium powder dirt of admixture in the present invention, owing to its mean diameter is at 0.05-0.1um, specific surface area is 25-
35m2/ g. has fabulous filling and " ball lubrication " effect, and physics water-reducing effect is notable, and water-reducing rate is up to more than 9%.Pass through
Repeatedly cement paste and glue sand test find that it not only can slightly improve strength of cement mortar, also can reduce cement normal consistency,
There is water reducing ability (seeing table 1).
Table 1
3, the present invention is compared with like product of the prior art, has preparation process simple, it is not necessary to special process equipment.
Meanwhile, the prices of raw materials of the present invention are cheap and market ample supply of goods, and therefore, Productive statistics is little, with low cost.
4, nanometer base cement modifier volume of the present invention be cement quality 8% time；Cement cost declines 10 yuan/ton, cement
Performance improvement situation sees table 2.Good stability of the present invention, it is possible to long term storage (at least more than 6 months)
Table 2
Remarks: cement is P.C32.5 grade composite silicate cement.
5, modified effect of the present invention is good, it is adaptable in the common portland cement of all kinds of specifications and models of non-retardation setting type.
