Description
Technical field
The present invention relates to a kind of preparation methods of anti-freezing type concrete, belong to anti-freezing type technical field of concrete preparation.
Background technology
Concrete refers to by cementitious material by the general designation of the cementing integral engineered composite material of aggregate.The coagulation usually said
A native word refers to making cementitious material, sand, masonry aggregate with cement；With water（Additive and admixture can be contained）Match by a certain percentage
Close, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in civil engineering.German construction in 1884
Company has purchased the patent of not Neil, has carried out the scientific experiment of first armored concrete, has had studied the strong of armored concrete
Degree, refractory ability.The cohesive force of reinforcing bar and concrete.The meter of armored concrete has been delivered in German engineer Cologne first within 1887
Calculation method；British Wilson application armoured concrete slab patent；U.S. sea of faces strategic point is special to test concrete beam.
The ratio of mud that Abrams in 1918 has delivered famous calculating concrete strength is theoretical.Armored concrete, which starts to become, changes this
The important materials of a world's landscape.From 19th century after Portland cement occurred in the 20's, due to the concrete being configured to it
With the required intensity of engineering and durability, and raw material is easy to get, and cost is relatively low, and especially energy consumption is relatively low, thus purposes pole
It is extensive.Simultaneously as the high level of architectural design and superelevation stratification, large span, underground and the harsh development of environment become
Gesture, high-strength and super high strength high performance concrete have in the heavy constructions such as high-rise building, bridge spanning the sea, offshore production platform
Application advantage outstanding.But hydration heat of concrete used at present is high, shrinkage cracking, volume stability are easy in low temperature
Difference, the external world corrode ion and easily migrate into inside concrete, and concrete is caused to be susceptible to steel bar corrosion, shadow in hypersaline environment
Ring its service life.
Invention content
The technical problems to be solved by the invention：Occur during preparation and use for conventional concrete, low
Easy shrinkage cracking when temperature, volume stability is poor, and the external world corrodes ion and easily migrates into inside concrete, and concrete is caused to exist
The problem of easily occurring steel bar corrosion in hypersaline environment, influencing its service life, the present invention is first with waste tire cheap and easy to get
Rubber powder is raw material, the hybrid reaction after calcium hypochlorite and sodium hypochlorite compounding, then is aided with hydrogen peroxide, makes crumb rubber activation, through filtering
After washing is dry, activated rubber powder is obtained, styrene etc. is recycled to prepare mixed emulsion, mixes, passes through in proportion with cement, yellow ground etc.
Stir to get anti-freezing type concrete.The present invention is attached to concrete and activated rubber powder using mixed emulsion in inside concrete dehydration
Surface improves the adhesion strength and compatibility of activated rubber powder and concrete, forms continuous membrane structure, improve the intensity of concrete
Performance and fracture toughness make concrete have excellent frost resistance under the conditions of low-temperature working.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）200~300g waste-tyre rubber-powders, 20~30g calcium hypochlorites are weighed successively, and 10~15g sodium hypochlorite is added
In the flask for filling 1~2L deionized waters, then beaker is placed on water-bath magnetic stirring apparatus, in temperature be 65~75 DEG C, rotating speed
Under the conditions of 400~600r/min, constant temperature is stirred to react 15~20min, then under stirring, by dropping funel to burning
It is 20~25% hydrogen peroxide that 200~300mL mass fractions are added dropwise in bottle, and control drips off in 30~45min, waits being added dropwise, after
Continuous constant temperature is stirred to react 45~60min；
（2）When reaction to the end of, filter while hot, remove filtrate, be washed with deionized filter cake until cleaning solution be in neutrality, then
Filter cake is transferred to vacuum drying chamber, under the conditions of temperature is 75~80 DEG C, dry 4~6h obtains activated rubber powder, spare；
（3）It counts in parts by weight, sequentially adds 100~110 parts of deionized waters in batch mixer, 60~80 parts of styrene,
30~40 parts of butadiene, 1~3 part of acrylic acid, 6~8 parts of Tea Saponins, 0.2~0.4 part of neopelex, 0.2~0.4
Part ammonium persulfate is 45~50 DEG C in temperature, under the conditions of rotating speed is 1200~1400r/min, constant temperature is stirred 20~
30min, discharging, obtains mixed emulsion；
（4）It counts in parts by weight, 160~180 parts of deionized waters is sequentially added in concrete mixer, 4~6 parts wooden
Plain sodium sulfonate water-reducing agent, 250~300 parts of portland cements, 600~700 parts of yellow ground, 800~1200 parts of stones, 60~80 parts of steps
Suddenly（2）Spare activated rubber powder, 40~60 parts of above-mentioned gained mixed emulsions are stirred under the conditions of rotating speed is 60~80r/min
30~45min is to get anti-freezing type concrete.
The present invention application process be：Anti-freezing type concrete obtained by the present invention is layed in extremely frigid zones road surface, adjustment paving
If thickness is 14~16cm, then makes road surface average flatness be 5~8mm through manual amendment, 2~4 are conserved with covered rearing with plastic film
It, then 28~30 days road surfaces being laid with to get concrete of natural curing.After testing, compression strength is reachable after maintenance of surface
75.6~80.2MPa, after 300~500 freezing-thawing tests, rate of weight loss is 2.2~2.4%, relative dynamic elastic modulus 85
~89%, compared with traditional concrete pavement, durability significantly improves.
The beneficial effects of the invention are as follows：
（1）Preparation method of the present invention is simple, using waste-tyre rubber-powder as raw material, waste tire is made to be fully used,
Its added value is improved, while concrete road strength character and fracture toughness being made to be improved, is conducive to anti-freezing type concrete
Sustainable development has both social enviroment protection meaning；
（2）Gained anti-freezing type concrete of the invention is applied to extremely frigid zones pavement construction, can extend making for concrete road surface
With the service life, road maintenance frequency is reduced, reduces the waste of resource and the energy, is easy to industrialized production and promotes and implement, have wide
General application prospect.
