Abstract
The present invention proposes a kind of smoothing preparation of concrete surface and preparation method thereof, including following components composition：Releasing agent 80 87wt%, the 17wt% of water reducer 10 and the 7wt% of initiator 2.Then preparation method is mixed and stirs to weigh releasing agent 80 87wt%, the 17wt% of water reducer 10 and the 7wt% of initiator 2.The smoothing preparation is applied to concrete, improves the problem of surface hole defect is excessive after concrete form removal.
Description
Technical field
The invention belongs to technical field of concrete additives, and in particular to a kind of smoothing preparation of concrete surface
And preparation method thereof.
Background technology
Armored concrete its surface after form removable there may be pitted skin, dew muscle, honeycomb and hole etc. and lack
Fall into.These are frequent common faults in reinforced concrete work.The characteristics of hole, is had time in component
Chamber (hand or rod etc. can be stretched into, or have can be by the phenomenon of object) it is local without concrete.Hole type
Into the reason for it is as follows：Concrete vibrating leakage, layering is poured when smashing, and vibrating spear is reached in next layer concrete,
Levels are caused to be come to nothing；Blanking of vertical member is too many, and the slump is relatively small, and concrete is by reinforcing bar etc.
Block, bottom arching withstands top concrete, if will appear from bottom hole after bottom leakage, form removal；It is mixed
Debris, wooden unit etc. are mixed into solidifying soil, hole can also be formed by as a result being taken out after form removal after wooden unit, debris；Steel
The intensive place's preformed hole of muscle or built-in fitting periphery, it is obstructed during due to concreting, it is impossible to the shape full of template
Into hole.
The general processing method of hole focuses on prevention, and specific method is as follows：The insertion depth of vibrating spear, it is maximum
1.25 times of vibrating spear effect partial are must not exceed, vibrating spear must not be reached and be vibrated in next layer concrete；
The blanking depth of vertical member should be less than 1.25 times of vibrating spear effect partial, must not leakage；If concrete is poured
Find there is wooden unit or debris before building, should take out in time；At the intensive place of reinforcing bar, preformed hole or built-in fitting periphery should
Take measures, fill up concrete, and vibration compacting.But often effect is not ideal enough, concrete demoulding
Its surface still has hole afterwards.
The content of the invention
The problem of to solve to there is hole after the existing concrete demoulding, the present invention proposes that a kind of concrete surface is used
Smoothing preparation, its be applied to concrete, improve concrete form removal after surface hole defect it is excessive the problem of.
The technical proposal of the invention is realized in this way：
A kind of smoothing preparation of concrete surface, including following components composition：Releasing agent 80-87wt%, subtracts
Aqua 10-17wt% and initiator 2-7wt%.
Further, the releasing agent is made up of the extract of animal fat with polyurethane thickener.
Further, the mass ratio of the extract of the animal fat and the polyurethane thickener is 5-6:1.
Further, the water reducer is made up of methyl allyl polyoxyethylene ether, acrylic acid and sodium hydroxide.
Further, the initiator is ammonium persulfate.
It is a further object to provide a kind of preparation method of the smoothing preparation of concrete surface, weigh
Releasing agent 80-87wt%, water reducer 10-17wt% and initiator 2-7wt%, are then mixed stirring
It is uniform.
Further, the releasing agent is made up of the extract of animal fat with polyurethane thickener.
Further, the mass ratio of the extract of the animal fat and the polyurethane thickener is 5-6:1.
Further, the water reducer is made up of methyl allyl polyoxyethylene ether, acrylic acid and sodium hydroxide.
Further, the initiator is ammonium persulfate.
Beneficial effects of the present invention：
The smoothing preparation of the concrete surface of the present invention is applied to concrete, and surface hole defect is equal after concrete form removal
No more than 2.
