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