Description
Technical field
The present invention relates to cement-based gelling material chemical technology field, and in particular to a kind of cement-based gelling material mixture
A kind of high-adaptability coagulation for producing certain expansion compensation cement-based gelling material early-age shrinkage can be continued by losing before the plastic stage
Soil is with subtracting jelly.
Background technology
It is a kind of functional form concrete emerging in construction market that concrete, which subtracts jelly (Cement Reducing Agent),
Additive, when its volume is the 0.6%~1.0% of binder materials, can make every side's concrete reduce by 8%~15% glue material use
Amount, it is roughly the same with concrete flowability energy, the intensity of not mixing CRA, so as to reach the effect for subtracting glue.The application for subtracting jelly may be used also
Improve the new workability for mixing and stirring maturing, promote the development of concrete new technology, promote industry byproduct in gelling
Application in material system, additionally aids and economizes on resources and environmental protection, has progressively turned into quality concrete essential
Material.Concrete subtracts lateral reactivity of the jelly mechanism of action for auxiliary excited cement particle dispersion, to greatest extent excited cement,
Promote the hydration reaction of cement more abundant；In addition concrete, which subtracts jelly, can strengthen the quantity and cohesive force of cement slurry, improve
Concrete flowability, encapsulation and water-retaining property, save the cement consumption of concrete during Practical Project is built.
Subtract the common key component of jelly for triethanolamine, triisopropanolamine.Triethanolamine, triisopropanolamine are to have sky
Between three-dimensional molecular structure, micro- dispersion effect is produced to cement granules.Triethanolamine plays the role of to promote mineral phased soln, promotes
C-S-H formation, and calcium ion and aluminium ion concentration are reduced by complex reaction, and then promote C3A aquations；Triisopropanolamine can
The nucleation of agstone is excited, is more easy to respect to triethanolamine and Fe3+Generation complex reaction, promotes the ferrite of more difficult aquation
Aquation reach improve cement minerals degree of hydration, promote hydrated product interlaced, so as to improve early strength and effective
Excited cement later strength, improve concrete compactness.
The A of patent CN 103787609 disclose a kind of concrete with jelly and preparation method thereof is subtracted, and subtract jelly with as follows
Recipe ingredient：25-45% mixed alcohol glue, 5-20% mixed alcohol, 5-15% melamine high efficiency water reducing agent, 2-5% catalysis
Agent, surplus are water.The A of CN 104119014 disclose a kind of concrete and subtract jelly, by mass percentage, and this, which subtracts jelly, has such as
Lower recipe ingredient：1%~3% phosphonate derivative A, 2%~5% hydroxy-aromatic compound B, 8%~13% alkyl
Amine C, surplus is water, the phosphonate derivative A, the 15% of hydroxy-aromatic compound B and alkylamine C total amount.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned present situation, it is desirable to provide a kind of multiple with polycarboxylic-acid, naphthalene system, aliphatic water reducing agent
Conjunction is used, and can increase the rheological property of cement-based gelling material mixture, improves mixture workability；It can ensure that concrete early stage

It is several；
The alkali-resistant penetrant is OPEO, aliphatic alcohol polyoxyvinethene phosphate or isooctanol polyoxy second
Alkene ether phosphate.
When the present invention is with polycarboxylic-acid, naphthalene system, aliphatic water reducing agent compound use, to cement-based gelling material mixture
Rheological property has slight increase effect, has improvement result to mixture workability.Alcohol amine compound, alcohol aldehydes in instant component
Compound can be to C3A、C4AF is fast, and hard mineral facies produce collaboration peptizaiton, and Ludox can further excite C3S、C2S host phases
Hydration rate and process, melamine system water reducer supplement a part of diminishing effect, and ensure that early strength is up to standard, alkaline-resisting infiltration
Agent can necessarily aid in improving the osmosis of above-mentioned surfactant.
