Description
Technical field
The present invention relates to a kind of concrete pore passage grouting agent and preparation method thereof, is a kind of concrete admixture class material of construction.
Background technology
Hole path pressure grouting agent operative norm has: JC/T986-2005 " cement-based grouting material ", JGJ/T70-2009 " building mortar basic performance tests method standard " hole path pressure grouting agent, TB/T3192-2008 " railway post stressed concrete beam pipe mudjacking technical qualification "; Its scope of application: the hole path pressure grouting agent can be used for anchoring and the grouting in prestress bridge duct, prevents underground water corrosion reinforcing bar (such as the stone anchoring) and steel strand (such as the prestretching wirerope).Because its thixotropy more is adapted to grouting overhead.From using pregrouting and the post-grouting that minute anchor pole and steel strand is arranged.
The grouting agent level of selling on the market is uneven, all can not satisfy " railway post stressed concrete beam pipe mudjacking agent technical qualification " fully.In actual mud jacking construction, majority all is to select simultaneously the admixture mixing of multiple different varieties to make to reach the technological standard requirement.And existing grouting agent can not use in the environment of alternation of wetting and drying, high and low temperature alternative.
Existing grouting agent rate of expansion is low, improves the fluidity of slurry ability, and without positive effect, and unstable properties is along with the prolongation effect of shelf lives alters a great deal to the slurry strength increase.The Xinjiang region temperature variation is larger, and currently available products can't be resisted freeze-thaw damage.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, a kind of hole path pressure grouting agent and preparation method thereof is provided, hole path pressure grouting agent stable performance of the present invention, heatproof is respond well, can resist freeze-thaw damage, can satisfy the larger condition service requirements of Xinjiang region temperature variation, and the preparation method is simple, easy to use.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of hole path pressure grouting agent, described hole path pressure grouting agent is mixed by following parts by weight of component: 40 parts of A component expansion components, the B component improves mobile component 20, the C component improves 20 parts of intensity components, 3 parts of D component freeze-thaw-material components, 7 parts of E component water-retaining components, F component are regulated 10 parts of components time of coagulation.
A component expansion component is evenly mixed by 30 weight part aluminum oxide and 10 weight part calcium hydroxides and forms;
It is polycarboxylate that the B component improves mobile component;
C component raising intensity component is mixed by 5 weight part Sodium Fluorides, 10 weight part nitrocalcite and 5 weight part calcium hydroxides and forms;
D component freeze-thaw-material component is colophonium pyrolytic polymer;
E component water-retaining component is Xylo-Mucine;
The F component is regulated component time of coagulation and is mixed by 4 weight part Trisodium Citrates and 6 weight part sodium polyphosphates and form.
The present invention discloses the preparation method of described hole path pressure grouting agent, after A component, B component, C component, E component and F component fully mixed, it is that 1% solution evenly is sprayed onto in the above mixture that the D set of dispense is set to weight concentration, after the oven dry, grinding to fineness reaches 400 orders, 40kg/ bag packing.
Among the present invention, the A component is aluminum oxide and calcium hydroxide, and the ettringite that chemical reaction generates volumetric expansion occurs for both, reach the effect of expansion, and mechanism stable is finished in this reaction in cement hydration process.
The B component is polycarboxylate, is the obvious super fluidizer of a kind of sterically hindered effect, greatly improves the flowability of slurry.
The C component is Sodium Fluoride, nitrocalcite, calcium hydroxide, and activity that can the excited cement adulterant reaches and puies forward high-intensity effect.
The D component is colophonium pyrolytic polymer, can form stable performance, the small even bubble of geometrical dimension in slurry, discharges that slurry is subjected to freeze thawing and the frost-heave force that produces.
The E component is Xylo-Mucine, can form a skim on the slurry surface, stops the moisture evaporation to reach the water conservation effect.
The F component is Trisodium Citrate and sodium polyphosphate, prolongs the latent period of cement, thereby regulates slurry time of coagulation, guarantees that simultaneously fluidity of slurry keeps good.
Hole path pressure grouting agent stable performance of the present invention, heatproof is respond well, can resist freeze-thaw damage, can satisfy the larger condition service requirements of Xinjiang region temperature variation, and the preparation method is simple, and is easy to use.
