Abstract
The present invention provides a kind of concrete of emergency, the raw material of the concrete of the emergency includes: the magnetized fly ash compound fertilizer for accounting for the raw material gross weight 5%-30%, the sand for accounting for the raw material gross weight 25%-40%, the cement for accounting for the raw material gross weight 20%-55% and the latex for accounting for the raw material gross weight 10%-20%；The concrete of the emergency is the mixing of 100:25-45 ratio according to raw material and water weight ratio by the raw material and water.The concrete setting time of emergency of the invention is short, and compression strength after short time solidification, when being applied to the repairing on road surface, bridge floor, can restore to use in 10 hours.
Description
Technical field
Mat formation the material for quickly repairing more particularly to a kind of emergency of disease the present invention relates to a kind of road surface, bridge floor etc.
Concrete.
Background technique
With the extension in road age of mating formation, there are some diseases in domestic road surface, bridge floor, such as crack, pit slot, loose.
The prior art generallys use some pitch class materials and carries out simple backfill punishment, under high temperature heavy load use condition, quickly can
Generate secondary breakage.Especially paving steel bridge deck, since use condition is more severe, conventional pitch patching material is often used
Several months just will appear high-temperature stability problem, be unable to satisfy requirement.
It is domestic also epoxy resin material to be selected to be repaired in recent years, imported material is generallyd use, it is expensive, and
Mostly bi-component epoxy needs to carry out the mixing of resin, curing agent and mineral aggregate at the scene, it is necessary to which scene is equipped with and mixes accordingly
It with equipment and generating equipment, constructs more difficult, input cost is high.
When carrying out road pavement reparation using epoxy material, usually in seam crossing brushwork epoxy resin binder, due to
Road asphalt is thermoplastic material, and epoxy resin belongs to thermosetting material, and works rigidity is very big, and material is partially crisp, by
When load action, the new and old seam mated formation is easier to generate secondary cracking, and service life reduces.
Summary of the invention
A kind of concrete of emergency is provided it is an object of the invention to overcome the shortcomings of the prior art place.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of concrete of emergency, the concrete of the emergency
Raw material includes: the magnetized fly ash compound fertilizer (PFAC) for accounting for the raw material gross weight 5%-30%, accounts for the raw material gross weight
The sand of 25%-40%, the cement for accounting for the raw material gross weight 20%-55% and the cream for accounting for the raw material gross weight 10%-20%
Glue；The concrete of the emergency is the mixing of 100:25-45 ratio according to raw material and water weight ratio by the raw material and water.
Preferably, the latex is epoxy latex or butadiene-styrene rubber.
Preferably, the raw material of the concrete of the emergency further includes the water-reducing agent for accounting for the raw material gross weight 1%-3%.
Preferably, the weight of the magnetized fly ash compound fertilizer accounts for the 20%-25% of the raw material gross weight.
Preferably, the weight of the sand accounts for 25%, 30%, 35% or the 40% of the raw material gross weight.
Preferably, the weight of the butadiene-styrene rubber accounts for the 15%-18% of the raw material gross weight.
The present invention also provides a kind of concretes of emergency as described in claim 1-6 is any in reparation road surface, bridge floor
Using.
The beneficial effects of the present invention are: the present invention provides a kind of concrete of emergency, when the concrete of the emergency solidifies
Between it is short, and the short time solidification after compression strength, be applied to road surface, bridge floor repairing when, can restore in 10 hours use.
