Description
Technical field
The present invention relates to a kind of basic crack fast repairing material more particularly to a kind of bi-component low viscosity type basic cracks
Fast repairing material.
Background technique
The advantages that base's intensity with higher, bearing capacity are high and plate body is strong, the use of base meet road surface knot
The requirement of " strong basis sake " in configuration formula, and construction cost is low.The road surface form of China's highway is mainly with semi-rigid type base
Based on bituminous pavement, and the use of semi-rigid type base has accounted for the 95% of bituminous pavement.But the temperature having due to semi-rigid material itself
Contracting, characteristic of dryness shrinkage easily lead to semi-rigid type base cracking, and cause when extraneous bad border variation and roadbed generate differential settlement
The crack can form reflection crack in road surface upwards along pavement structure, and the service performance of road pavement causes serious shadow
It rings.In order to reduce the harm of reflection crack, the crack that need to be generated to semi-rigid type base is timely repaired and is punished.
Processing for crack problem is usually to carry out surface layer milling to the more serious road surface of destruction in a short period of time
It digs, cementation of fissures processing or direct milling, are spread again at basic crack.But a large amount of time can be lost in making base again,
So the crack to base is repaired, it is not only economical, but also substantially reduce the duration.So the crack repairing material haveing excellent performance
Material repairing base becomes optimal selection naturally.
But existing crack patching material often has the following problems: often encountering adhesion strength when processing basic crack
Problem low, elasticity modulus is excessively high, base cannot bond together well with crack patching material, not have and bond base
Integral effect；The volume of traffic is big, and traction engine is more, and the crack patching material that impact load makes greatly elasticity modulus excessively high uses the longevity
Life greatly shortens.In addition, basic crack, in the cementation of fissures, since gap-grouting material viscosity is larger, tiny crack can not be poured into, cause
One kind is seen, is filled, and has only been filled wider part above actually, not can guarantee construction quality.
Summary of the invention
The bi-component low viscosity type with good workability that technical problem to be solved by the invention is to provide a kind of
Basic crack fast repairing material.
To solve the above problems, a kind of bi-component low viscosity type basic crack fast repairing material of the present invention,
Be characterized in that: the patching material is made of component A and B component；Wherein
The component A by weight, by 70 parts of quick hardening sulphoaluminate cement, 10 ~ 12 parts of flyash, 3 ~ 5 parts of silicon ash, silica flour
50 parts, 0.2 ~ 0.3 part of water-reducing agent, 3 parts of swelling agent, 0.1 part of defoaming agent, 0.42 ~ 0.45 part of boric acid, 0 ~ 0.2 part of cellulose mixing
It forms；
By weight, by 12 parts of carboxylic styrene butadiene latex, 38.25 ~ 46.75 parts of water mix the B component.
The strength grade of the quick hardening sulphoaluminate cement is 32.5 or 42.5 grades.
The grade of the flyash is I grade of flyash.
The specific surface area of the silicon ash is 2200m2/kg。
The partial size of the silica flour is 140 mesh ~ 300 mesh.
The water-reducing agent is high-efficiency water-reducing agent of poly-carboxylic acid.
The swelling agent is plastic expansion agent or calcium oxide expansion agents.
A kind of application method of bi-component low viscosity type basic crack fast repairing material as described above, feature exist
In: component A, component B are stirred with hand-held high speed agitator and complete to construct in 3 minutes, 20 minutes；After two hours, Ji Kekai
The compacting that paves of beginning surface layer.
Compared with the prior art, the present invention has the following advantages:
1, the present invention mainly provides the early strength of material by sulphate aluminium cement, flyash and silicon ash ternary system；By powder
The ball effect of coal ash improves mobility, and improves the adhesion strength at interface by carboxylic styrene butadiene latex and reduce elasticity modulus；By
Swelling agent solves early-age shrinkage, can effectively be dispersed to cement granules using high performance water reducing agent of polyocarboxy acid, and has good
Good space steric effect, so that patching material has good workability.
2, patching material of the present invention after tested, has good fluidity, setting time is fast, elasticity modulus is low, early strength is high,
The features such as adhesion strength is high is and good (referring to table 1) with base cooperative bearing, it can be achieved that exempt from the quick mortar depositing construction of pressure.
A kind of table 1: bi-component low viscosity type basic crack fast repairing material performance indicator
3, present invention employs two kinds of components of A, B to construct, and practice of construction is easy to use.
