Description
Technical field
The present invention relates to concrete material technical field, more particularly to it is a kind of can anti-sulfur dioxide corrosion canvas concrete
And preparation method thereof.
Background technology
Concrete structure can be destroyed and influence it normally to use in being chronically at the corrosive environments such as acid, salt.At present
It is mainly for the measure that concrete structure is protected and uses encased steel plate, stickup fibrous composite, external prestressing steels,
Enlarged cross section product is reinforced, and the measure such as displacement concrete strengthening is repaired to damaging concrete.These measures are substantially from changing
Become concrete structure aspect to start with, high cost, engineering difficulty is big, and the engineering time is long.These measures do not have in the resistance to of concrete
Long property aspect is played a role, and being applied in industrial environment can not play enhancing concrete well and support erosion-resisting effect.
Existing guard technology is mainly in concrete surface brush coating, though coating can effectively improve concrete structure
Antiseptic power, but at present there is no maturation building trade standard and detecting appraisal method
The content of the invention
In view of this, the present invention provide it is a kind of can anti-sulfur dioxide corrosion canvas concrete and preparation method thereof.
First, the present invention provide it is a kind of can anti-sulfur dioxide corrosion canvas concrete, it includes：3D screen cloths, and fill out
The cement filled between the space of the 3D screen cloths.
Further, the cement uses sulphate aluminium cement.
Accordingly, the present invention also provide it is a kind of can anti-sulfur dioxide corrosion canvas concrete preparation method, it includes：
Step a, cement flour pours into 3D screen cloths, and consolidated with concrete vibrator, with to be used；
Step b, when using, the canvas concrete that step a is made is routed on desired position, is then directly sprinkled water
Hardening can complete to prepare.
Further, the operation of watering stamp is specially in the step b：Canvas concrete is sprinkled water, until the canvas back of the body
Face is soaked, and untill being flowed out without unnecessary moisture.
The present invention provide aluminium sulfate canvas concrete in addition to good mechanical property, also with good corrosion resistant
Corrosion.Its preparation method is that scene is mated formation when in use, hardened forming of then sprinkling water during cement flour poured into 3D screen cloths.Its with
Normal concrete is compared, and eliminates the process of stirring and maintenance, can be used in engineering faster.Its advantage be convenient storage,
Transport, easy construction, it is time-consuming.
Specific embodiment
The invention discloses it is a kind of can anti-sulfur dioxide corrosion canvas concrete and preparation method thereof.People in the art
Member can use for reference present disclosure, be suitably modified technological parameter realization.In particular, all similar replacements and change
Apparent to those skilled in the art, they are considered as being included in the present invention.The method of the present invention and application
Be described by preferred embodiment, related personnel substantially can not depart from it is right in present invention, spirit and scope
Method described herein and application are modified or suitably change is realized and apply the technology of the present invention with combining.
The present invention provide it is a kind of can anti-sulfur dioxide corrosion canvas concrete.Concrete canvas (Concrete
Canvas) as a kind of new material, fabric reinforced cement composite is belonged to.It is main about the research of CC both at home and abroad at present
Concentrate on and prepare tent using CC, as a kind of provisional building, in military defense project and earthquake relief work.Using CC as
Planting protective materials is used for industry SO2Research in environment is also very rare.The material of concrete canvas is usually (to be washed by polyester fiber
Synthetic fibre) it is made, fiber has certain acid resistance in itself, therefore concrete canvas is used for industry SO as a kind of outsourcing material2Ring
The erosion of sour gas internally structure can be slowed down on concrete structure in border, it is ensured that building can reach design requirement
Service life.
The present invention provide can the canvas concrete of anti-sulfur dioxide corrosion include：3D screen cloths, and it is filled in the 3D
Cement between the space of screen cloth.
The 3D screen cloths are commonly called as special thickness sandwich eyelet fabric, also referred to as 3D materials or 3D space fabrics, and it belongs to through needle
Fine work inside weaving cotton cloth, using Polymer Synthesizing fiber, by accurate board, disposably braiding is formed, with the design of double-deck mesh, in
Between monofilament with X-90 ° of vertical array, it is had breathable moisture permeability, make its durable in use.
Preferably, the cement uses sulphate aluminium cement.
The present invention provide it is above-mentioned can anti-sulfur dioxide corrosion canvas concrete, in addition to good mechanical property,
Also there is good corrosion resistance, be suitable for the application of in concrete structure.
Accordingly, the present invention also provide it is a kind of can anti-sulfur dioxide corrosion canvas concrete preparation method, it includes：
Step a, cement flour pours into 3D screen cloths, and consolidated with concrete vibrator, with to be used；
Step b, when using, the canvas concrete that step a is made is routed on desired position, is then directly sprinkled water
Hardening can complete to prepare.
Further, the operation of watering stamp is specially in the step b：Canvas concrete is sprinkled water, until the canvas back of the body
Face is soaked, and untill being flowed out without unnecessary moisture.
In above-mentioned preparation method, in the preparation, during cement flour poured into 3D screen cloths, scene is mated formation when in use, is then spilt
Water hardening is molded.It eliminates the process of stirring and maintenance compared with normal concrete, can be used in engineering faster.Its
Advantage is to facilitate storage, transport, easy construction, time-consuming.
With reference to embodiment, the present invention is expanded on further：
Embodiment
3D screen cloths and cement are selected in the preparation of test specimen in experiment.The wherein selection sulphate aluminium cement of cement, its performance is such as
Shown in table 1.3D screen cloths are cut into 200mm × 300mm rectangles by test specimen before making, and then cement flour are circulated into 3D screen cloths, most
Concrete canvas test specimen is sprinkled water afterwards, until the canvas back side is soaked, untill there is no unnecessary moisture to flow out.In treating canvas concrete
The abundant aquation of cement flour after, test block is put into natural environment and is conserved.
The sulphate aluminium cement performance indications of table 1
Vulcanization experiment reference《Normal concrete chronicity and durability test method standard》(GB/T 50082-2009)
In requirement on carbon dioxide to concrete carbonization part carry out vulcanization experiment.The concentration of SO2 is set as during vulcanization
1000ppm, temperature is 25 DEG C ± 1 DEG C, and humidity is 80% ± 1%.Condition carry out vulcanization experiment.Aluminium sulfate sail before and after vulcanization
Every experimental performance index change of cloth concrete is as shown in table 2.
Each experimental performance change before and after the vulcanization of the aluminium sulfate canvas concrete of table 2
The aluminium sulfate canvas concrete of present invention offer is can be seen that except with good power by the data in table 2
Learn outside performance, also with good corrosion resistance.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
