The viscosity reinforcing agent further has the water reducing function while the technical problems of bleeding, slurry floating and the like of a cement-based composite material are solved, the usage amount of the water reducing agent of the cement-based composite material is decreased, the usage amount of the viscosity reinforcing agent can be adjusted according to different air temperatures and different construction applications to meet the construction requirements, and the viscosity reinforcing agent has the advantages of being wide in application range and convenient to use.
Description
Technical field
Patent of the present invention belongs to building material field, particularly relates to a kind of cement-base composite material and includes cement mud-jack material
The special viscosity intensifiers such as (agent), grouting material, gravity flowing levelling mortar and self-compacting concrete.
Background technology
Cement-base composite material is because of the economy of its uniqueness, technical advantage in engineering construction and maintenance field purposes increasingly
Extensively, prestress hole path pressure grouting material, gravity flowing levelling mortar, early-strength grouting material, self-compacting concrete etc. play in respective use field
Huge effect.Above-mentioned composite is in addition to having Self-leveling, without vibration requirement, to bleeding, laitance, blibbing, stability
Etc. aspect have higher requirement.Cement-base composite material stability has been done strict regulation by Domestic Correlative Standard, such as
" highway engineering prestressed pore passage grouting material (agent) " JT/T 946-2014 regulation mud jacking serosity bleeding rate is 0%, fullness degree closes
Lattice, " cement-based grouting material application technology specification " GB/T 50448-2015 regulation grouting material bleeding rate is 0%, " high-speed railway
The CRTS III plate-type provisional technical conditions of non-fragment orbit self-compacting concrete " TJ/GW 112-2013 regulation self-compacting concrete expansion
The latitude of emulsion≤680mm, expansion time T500 are 3～7s, bleeding rate is 0%.
For realizing zero bleeding, purpose without laitance, water-retaining component or viscosity modifying material mode are added in domestic usual employing
Realize, as CN 102060468 B discloses a kind of grout additive, use water-retaining component such as hydroxypropyl two starch phosphate fat
Or the one in phosphorylation PASELLI EASYGEL and sodium carboxymethyl cellulose, hydroxyethylmethyl-cellulose, hydroxypropyl methyl fiber
A kind of problem according to equal quality ratio compound solution filling process cement mortar bleeding in element or polyvinyl alcohol, which exists
The problems such as bad adaptability, anti-bleeding difference, run into the cement DeGrain that some cement granules are big, tricalcium aluminate content is low.Pin
The problem more to self-compacting concrete bleeding, laitance and blibbing, domestic scholars is studied and achieves certain one-tenth
Really, as CN 104829160 A discloses a kind of special viscosity modified material of CRTS III template self-compacting concrete, but using
During this viscosity modifying material addition fixing after be difficult to adjust according to sand, building stones change, mobility once occurs
Being deteriorated, can only adjust by increasing water reducer or water consumption, itself does not have diminishing function.Meanwhile, viscous disclosed in above-mentioned patent
Spend the material modified effect not possessing and adjusting concrete coagulating time, particularly under the conditions of low temperature or construction at high temperature, it is difficult to protect
The normal construction of card.
Summary of the invention
The invention provides a kind of special viscosity intensifier of cement admixture having diminishing function concurrently, multiple solving cement based
While the technical problems such as condensation material bleeding, laitance, also there is certain diminishing function, decrease cement-base composite material diminishing
The consumption of agent, can meet the requirement of construction, have purposes wide according to the difference of temperature, construction purposes by adjusting its consumption
Feature general, easy to use.
Realizing the technical scheme that above-mentioned purpose of the present invention used is:
A kind of special viscosity intensifier of cement admixture having diminishing function concurrently, including following components, each component and each
Mass percent shared by component is:
The particle diameter of described dicalcium powder is 1～200 micron, limestone mine, calcite ore form through high-energy ball milling；

Described adhesion promoting component is the methyl cellulose ether of viscosity 200～500mpa.s, the moon of molecular weight 500～20,000,000
Cationic polyacrylamide, the starch ether of viscosity 400～1200mpa.s, thixotroping value are not less than one or two in the thixotropic lubricant of 8
Plant the mixture that any of the above ratio is compounding.
Described diminishing component is to subtract the mixing that one or both arbitrary proportions in colloid, polycarboxylate water-reducer are compounding
Thing；
Regulate described setting time component be calcium sulphoaluminate, calcium formate, lithium salts, sodium gluconate, boric acid, tartaric acid and
The mixture that in citric acid, one or more arbitrary proportions are compounding；
Described suds surely steep component be polymethyl siloxane defoamer, mineral oil antifoam agent one or both arbitrarily than
The mixture that example is compounding.
Compared with prior art, the invention have the advantages that
1, the present invention is added with spherical SiO2Powder body, described diameter of particle is 50～200nm, and particle diameter reaches nanoscale,
The property of nano material makes cement admixture stability be improved；Meanwhile, spheroidal particle plays one in the mixture
Fixed " ball " effect, improves the mobility of mixture.
2, in the present invention diminishing component be subtract colloid, polycarboxylate water-reducer one or both, subtract colloid and subtract with polycarboxylic acids
Water preparation coordinative role promotes the dispersion of the big flocculent structure of cement so that Free water fully discharges, and improves the mobility of mixture.
3, in the present invention, suds surely steeps the addition of component, effectively inhibits cement admixture bubble in stirring preparation process
Generation；Make inside bubble stable existence mixture after cement grout, self-compacting concrete have irrigated, effectively reduce connecing
Contacting surface number of bubbles, prevents the generation of the disease such as cavity, honeycomb.
