It connects integral, due to the incorporation of redispersable latex powder, makes this product and substrate that there is preferably bonding and osmosis, increase
Add adhesion strength and toughness, reduce elasticity modulus, improve resistance to compression, tension, bending resistance, impact strength, improve collapse resistance toughness, improves
Overall structure anti-seismic performance.
Specific embodiment：
The invention will be further described With reference to embodiment：
A kind of prefabricated components connection grouting material, by mass percentage, including following components, PO52.5 cement 35%,
S105 slag micropowder 11.5%, 2.5-5mm quartz sand 8%, 1.25-2.5mm quartz sand 10%, 0.63-1.25mm quartz 17%,
0-0.63mm quartz sand 15%, steel fibre 0.5%, low-viscosity cellulose ether 0.1%, water-reducing agent 0.2%, swelling agent 0.1% disappear
Infusion 0.1%, redispersable latex powder 2.5%.
Wherein, being classified storage after drying using the quartz sand of fineness modulus 3.0-3.1 is respectively：2.5-5mm quartz sand,
1.25-2.5mm quartz sand, 0.63-1.25mm quartz, 0-0.63mm quartz sand；Water-retaining agent is hydroxypropyl methyl cellulose ether, swollen
Swollen dose is calcium oxide expansion agents, using calcium oxide as expansion sources, it is jointly levigate in 1 to 1 ratio by calcium oxide and stearic acid and
At；Defoaming agent is aliphatic compound and organic silicon composite, and water-reducing agent is polycarboxylate dehydragent.
The effect of each material in the present invention
Slag micropowder selects pulverized slag powder S105, increases mobility, improves later strength and durability.
Steel fibre improves resistance to compression, tension, bending resistance, impact strength, improves collapse resistance toughness, improves overall structure shock resistance
Energy.
Hydroxypropyl methyl cellulose ether is water-retaining agent, viscosity 400, in the case where improving water retention does not influence mobility,
Avoid excreting water phenomenon.
Polycarboxylate dehydragent has preferable dispersion effect, higher water-reducing rate, keep the lasting mobility of mortar and
Stability, to ensure that the stabilization of compactness and performance indexes.
Swelling agent：Calcium oxide expansion agents are total to by calcium oxide and stearic acid in 1 to 1 ratio using calcium oxide as expansion sources
With levigate, calcium oxide surface adhesion stearic acid forms one layer of stearic acid film in grinding processes, prevents calcium oxide from directly and water
Haptoreaction delays the hydration rate of calcium oxide, and stearic acid film gradually ruptures in hydration process, so that expansion rate is controlled,
It reduces and shrinks, increase volume stability and improve compression strength.
Redispersable latex powder：Rubber powder forms film and is uniformly distributed different location in the slurry, makes which give rigid water
The characteristic that material-mud can not have：Cohesion, high-tensile, elasticity, flexibility, low elastic modulus improve component connection
Shock resistance, bending resistance and overall stability.
Defoaming agent：Aliphatic compound and a small amount of organic silicon composite reduce the air content in slurry, and it is close to increase slurry
Degree, the strengths in tension and compression after improving slurry hardening, increases slurry initial fluidity, the compactness after improving slurry hardening.
Dry blend of the present invention through stirring, after adding water and stirring have good mobility, higher early stage, after
Phase intensity, higher flexural strength, microdilatancy ungauged regions, dense packing effect make various shapes in the gap of sleeve and Dai Gang Zhu
The cement base prefabricated components of shape securely connect integral, raising collapse resistance toughness, raising overall structure anti-seismic performance.
