Abstract
The invention discloses a high-polymer quick structure repairing material special for a bridge expansion joint and a preparation method of the high-polymer quick structure repairing material. The high-polymer quick structure repairing material is prepared from the following raw materials in parts by weight: 250 to 400 parts of cement, 200 to 450 parts of quartz sand, 200 to 400 parts of pebbles, 10 to 40 parts of polymer, 1 to 5 parts of high-molecular polymer, 10 to 50 parts of composite expanding agent, 1 to 5 parts of early strength agent and 0.3 to 1.2 parts of polycarboxylate superplasticizer, wherein the polymer is redispersible powder, and the high-molecular polymer is cellulose ether. The early strength of novel concrete is high, and the novel concrete can be used after three hours; the bonding force between the novel concrete and old concrete is greatly enhanced, corrosion of reinforcement is avoided, and the service life of the novel concrete is greatly prolonged.
Description
Technical field
The present invention relates to architecture engineering material technical field, be specifically related to a kind of special high polymer of bridge expanssion joint fast
Speed structure repair material and preparation method thereof.
Background technology
At present, on-the-spot mixing proportioning inaccurate and pollute environment, strength development slowly affect be open to traffic the time (duration),
Linking new and old concrete intensity is low affects service life, repairing novel concrete shrinkage deformation effect new-old concrete one
Cause property (impact be open to traffic effect), manually water to smash and affect repairing quality etc..
Summary of the invention
It is an object of the invention to overcome the shortcoming and defect of prior art, it is provided that a kind of intensity is high, and the time is short,
Cohesive force is strong, stops steel bar corrosion, and the special high polymer of bridge expanssion joint extending novel concrete service life is quick
Structure repair material and preparation method thereof.
A kind of bridge expanssion joint special high polymer rapid structural material for repairing of the present invention and preparation method thereof is to pass through
Techniques below scheme realizes:
A kind of bridge expanssion joint special high polymer rapid structural material for repairing, it is to be joined by weight by following raw material
It is fabricated by than with method:
Proportioning:
Cement 250～400 parts, quartz sand 200～450 parts, stone 200～400 parts of polymer, polymer
10～40 parts, high molecular polymer 1～5 parts, compound extender 10～50 parts, early strength agent 1～5 parts,
Polycarboxylate water-reducer 0.3～1.2 parts, wherein said polymer is redispersable latex powder, described polyphosphazene polymer
Compound is cellulose ether.
Manufacture method:
1), cement, quartz sand importing equipment are imported respective pre-homogenizing storehouse and carries out pre-homogenizing；
2), control to carry out continuous batching by computer according to above-mentioned part by weight；
3), compound mixed at high speed 3-5 minute in HZ-20 type forced stirrer of preparing, then middling speed mixing
2.5-4.5 minute；
4) dry mash, mixed imports finished product homogenizing storehouse；
5), electronic measurement is packed automatically；
6), finished product warehouse-in.
The present invention is factorial praluction under electronic computer control, and proportioning is precisely consistent, produces continuously；High bone strengthening
The application of material (quartz sand) is the basis of concrete high-strength；Vast scale (such as 3.5%) redispersable latex powder
Interpolation, concrete hole structure forms the thin film of continuously closing so that the corrosion resistance of concrete is greatly strengthened,
And strengthen at double with the cohesive force of old concrete, improve corrosion resistance and the durability of concrete.
The interpolation of extender compensate for the natural shrinking in concrete hydrating hardening process；The interpolation of early strength agent makes
Concrete high-strength is the strongest, for bridge expanssion joint and cement pavement bumpy repair, can be open to traffic after three hours；High
Effect water reducer and the use of polymer so that concrete not bleeding, self-compaction, and therefore promote that high-strength morning is strong
Realize.
The present invention uses factory's premixing large-scale production；The use of high-strength aggregate, and polymer, early strength agent,
The optimization of the multiple additive such as extender, water reducer is added in advance so that novel concrete not bleeding, self-compaction, greatly
Big Optimizing construction performance, solves the similar engineering such as cement construction of Deck Expansin Joint, cement pavement bumpy repair, by force
Degree slower development impact is open to traffic (using the time), linking new and old concrete intensity is low affects service life, scene
Mixing proportioning is forbidden to pollute environment, repairing novel concrete shrinkage deformation effect new-old concrete concordance, manually water
Smash problems such as affecting repairing quality.
Compared with prior art, the present invention a kind of bridge expanssion joint special high polymer rapid structural material for repairing and
Preparation method provides the benefit that: novel concrete early strength is high, can use after three hours；New-old concrete
Between cohesive force be greatly reinforced, stop steel bar corrosion, greatly extend service life of novel concrete.
