Description
Technical field
This application involves the realm of building construction, specifically a kind of maintenance agent prescription and its maintenance processes.
Background technique
Concrete curing is artificially to cause certain humidity and temperature condition, keep the concrete just poured normal or
Accelerate its hardening and gain in strength.Concrete is cement aquation as a result, and water so can gradually harden and increase intensity
The aquation of mud needs certain temperature and humidity condition.As ambient enviroment be not present the condition when, then need manually to concrete into
Row maintenance.After concrete casting, such as hot climate is air-dried, and is conserved not in time, and moisture can evaporate in concrete
Fastly, dehydrating phenomena is formed, the cement granules for having formed gelinite can be prevented from abundant aquation, stable crystallization cannot be converted into,
Lack enough cohesive forces, to sheet can occur in concrete surface or powdery falls off.In addition, not yet having foot in concrete
When enough intensity, the premature evaporation of moisture can also generate biggish contraction distortion, cup shake occur.So after concreting
The maintenance of initial stage is extremely important, should be conserved immediately after concrete final set, after dry concrete Ying Yu is poured
It is conserved immediately.
Existing concrete maintenance process has: one, natural curing: point sprinkling maintenance and spraying plastic membrane curing.The former uses
Straw screen or mat etc. covers concrete, and often watering keeps wet.Curing time depends on cement type, as ordinary portland cement is mixed
Solidifying soil no less than 7 is round the clock.The latter is suitable for being not easy towering structure and large area concrete structure of sprinkling maintenance etc., is by mistake
Vinyl chloride resin plastic solution is sprayed at concrete surface with spray gun, forms thin film in concrete surface after solution evaporation,
By concrete and air exclusion, moisture evaporation in concrete is prevented to guarantee that cement aquation is normally carried out, it is thin after the completion of maintenance
Film can voluntarily fall off in aging.Two, steam curing: concrete component is placed on and mixes with air object full of saturated vapor or steam
In fog room, accelerate concrete hardening in higher temperature and humidity environment.Maintenance effect is related with steam curing system, it is wrapped
It includes: time of repose, heating and cooling rate, curing temperature, thermostatic curing time, relative humidity etc. before steam curing.Steam is supported
There are pit, shaft kiln formula and tunnel-kiln type in shield room.
Curing compound, which is called, does concrete protectant, concrete nursing liquid, is one using modern high technology preparation
Kind novel high polymer preparation.A kind of liquid film forming compound that adaptability is very extensive, the product be it is aqueous, nontoxic non-ignitable,
It is easy to use, this curing agent is sprayed on concrete or mortar surface, when moisture evaporation to a certain extent, one layer can be quickly formed
Colourless, fluid-tight film can prevent the moisture evaporation in concrete or mortar, reduce concrete shrinkage and cracking.And it uses
Curing agent is conserved compared to direct sprinkling maintenance, not only saves water resource, while can effectively lock moisture, special needle
For special concrete pouring structure (metope or complicated concrete surface) poor problem of watering adhesion effect, it is capable of providing
Preferable maintenance effect.
But existing curing agent type is more, and because each component is formulated different, that there are film-formation results is poor, it is poor to disperse osmotic effect
Concrete part moisture loss when maintenance is caused comparatively fast to lead to the problem of slight crack.The side that concrete curing is carried out using curing agent existing simultaneously
Method is not quite similar, and fails to provide a kind of relatively stable and efficient maintenance construction scheme.
Summary of the invention

Experimental test project includes:
Water retention, concrete soil sample compression strength and wearability.
Water retention test method: the water-retaining property of the curing agent coating sprayed on new molding surface of concrete structure it is good
The bad every technical performance for directly affecting concrete.Experimental study is according to " cement concrete curing agent " (JC901-200) standard
Defined test method and main technique requirements make normal concrete test specimen and spraying curing agent concrete sample, examination respectively
Part exposed surface is having a size of 150mm*150mm, after the surface condition of test specimen reaches requirement, is accurately claimed to test specimen immediately
Amount, then again equidistantly equably puts test specimen in environmental cabinet, and record the cartonning time.It is taken out from environmental cabinet after 72h
Concrete sample simultaneously claims its quality respectively.
Compression strength: manufactured size is the concrete sample of 150*150*150mm, is then coated corresponding curing agent
The disposed within and corresponding method of use is conserved, and then demoulding carries out compressive strength test.
Wearability test: manufactured size is the concrete sample of 150*150*150mm, is then coated corresponding maintenance
Agent is disposed within and is conserved using corresponding method, and then demoulding carries out abrasion test, using stone mill under 200 turns
It rubs to concrete surface, and tests the weight difference and record of front and back.
Test result is as follows:
Maintenance performance first after the test of experimental group 1-5 all has preferable performance indicator compared to control group and other groups,
After only using special paraffin wax emulsions, dispersion effect is preferable, and the sample stratification situation of test is less, therefore the later period reaches
The performance indicator highest arrived.And after experimental group 6 lacks auxiliary agent, cause the curing agent film-formation result on concrete sample surface poor,
Then lead to the reduction of water retention index, while the mechanical property of concrete being caused also to have decline.And experimental group 7 is the absence of water absorbing agent,
Same water retention decline is more obvious；Experimental group 8 is the absence of stick, that is, thickener, therefore also results in concrete sample
Simulation shear wall surface maintenance situation is especially placed on multiple sample test surfaces by surface filming uneven thickness vertically in test
Afterwards, lead to lower part curing agent film forming preferably, and the obvious adhesion amount of the curing agent on top is less, then average water retention decline occurs.
And experimental group 9 is then to be also resulted in each group performance data using common maintenance process and be decreased obviously.
The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field
For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair
Change, equivalent replacement, improvement etc., should be included within the scope of protection of this application.
