Description
Technical field
The present invention relates to concrete material technical field, in particular to it is a kind of can anti-sulfur dioxide corrosion canvas concrete
And preparation method thereof.
Background technique
Concrete structure, which is chronically in the corrosive environments such as acid, salt, to be destroyed and influence its normal use.At present
It is mainly to use encased steel plate for the measure that concrete structure is protected, stickup fibrous composite, external prestressing steels,
Enlarged cross section product is reinforced, and damage concrete is repaired in the measures such as displacement concrete strengthening.These measures are substantially from changing
Start in terms of becoming concrete structure, at high cost, engineering difficulty is big, and the construction time is long.There is no in the resistance to of concrete for these measures
It is played a role in terms of long property, being applied in industrial environment can not play the role of enhancing well concrete to erosion-resisting.
Existing guard technology is mainly in concrete surface brush coating, though coating can effectively improve concrete structure
Anti-corrosion ability, but there is no mature building trade standard and detecting appraisal method at present.
Summary 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.
Firstly, the present invention provide it is a kind of can anti-sulfur dioxide corrosion canvas concrete comprising: 3D screen cloth, and filling out
Fill the cement between the gap in the 3D screen cloth.
Further, the cement uses sulphate aluminium cement.
Correspondingly, the present invention also provides it is a kind of can anti-sulfur dioxide corrosion canvas concrete preparation method comprising:
Step a, cement powder is poured into 3D screen cloth, and is consolidated with concrete vibrator, with to be used；
Step b, it in use, the canvas concrete that step a makes is routed on desired position, then directly sprinkles water
Preparation can be completed in hardening.
Further, it sprinkles water in the step b process of hardening specifically: sprinkle water to canvas concrete, until canvas is carried on the back
Face is soaked, and until not extra moisture outflow.
Aluminium sulfate canvas coagulation earth removal provided by the invention has outside good mechanical property, also has good corrosion resistant
Corrosion.Preparation method is to pour into cement powder in 3D screen cloth, and scene is mated formation when in use, hardened forming of then sprinkling water.Its with
Normal concrete is compared, and the process of stirring and maintenance is eliminated, and can be used in engineering faster.Its advantage is that facilitate storage,
It transports, is easy for construction, saving the time.
Specific embodiment
The invention discloses it is a kind of can anti-sulfur dioxide corrosion canvas concrete and preparation method thereof.Those skilled in the art
Member can use for reference present disclosure, be suitably modified realization of process parameters.In particular, it should be pointed out that all similar substitutions and modifications
Apparent to those skilled in the art, they are considered as being included in the present invention.Method and application of the invention
Be described by preferred embodiment, related personnel obviously can not depart from the content of present invention, in spirit and scope it is right
Method described herein and application are modified or appropriate changes and combinations, carry out implementation and application the technology of the present invention.
The present invention provide it is a kind of can anti-sulfur dioxide corrosion canvas concrete.Concrete canvas (Concrete
Canvas it) is used as a kind of new material, belongs to fabric reinforced cement composite.The research in relation to CC both at home and abroad is main at present
It concentrates on preparing tent using CC, becomes a kind of provisional building, in military defense project and earthquake relief work.Using CC as one
Kind 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 itself has certain acid resistance, 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, guarantee that building can reach design requirement
Service life.
It is provided by the invention can the canvas concrete of anti-sulfur dioxide corrosion include: 3D screen cloth, and be filled in the 3D
Cement between the gap of screen cloth.
The 3D screen cloth is commonly called as special thick sandwich eyelet fabric, also referred to as 3D material or 3D space fabric, it belongs to through needle
Fine work inside woven fabric is disposably woven using Polymer Synthesizing fiber by accurate board, has the double-deck mesh design, in
Between monofilament with X-90 ° of vertical array, so that it is had breathable moisture permeability, keep its durable.
Preferably, the cement uses sulphate aluminium cement.
It is provided by the invention 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.
Correspondingly, the present invention also provides it is a kind of can anti-sulfur dioxide corrosion canvas concrete preparation method comprising:
Step a, cement powder is poured into 3D screen cloth, and is consolidated with concrete vibrator, with to be used；
Step b, it in use, the canvas concrete that step a makes is routed on desired position, then directly sprinkles water
Preparation can be completed in hardening.
Further, it sprinkles water in the step b process of hardening specifically: sprinkle water to canvas concrete, until canvas is carried on the back
Face is soaked, and until not extra moisture outflow.
In above-mentioned preparation method, in the preparation, cement powder is poured into 3D screen cloth, scene is mated formation when in use, is then spilt
Water hardening molding.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 for construction, saves the time.
Below with reference to embodiment, the present invention is further explained:
Embodiment
3D screen cloth and cement are selected in the preparation of test specimen in test.The wherein selection sulphate aluminium cement of cement, performance is such as
Shown in table 1.3D screen cloth is cut into 200mm × 300mm rectangle before test specimen production, then cement powder is circulated into 3D screen cloth, most
It sprinkles water afterwards to concrete canvas test specimen, until the canvas back side is soaked, until not extra moisture outflow.To in canvas concrete
The abundant aquation of cement powder after, test block is put into natural environment and is conserved.
1 sulphate aluminium cement performance indicator of table
Vulcanization test is referring to " normal concrete chronicity and durability test method standard " (GB/T 50082-2009)
In requirement about carbon dioxide to concrete carbonization part carry out vulcanization test.The concentration of SO2 is set as when vulcanization
1000ppm, temperature are 25 DEG C ± 1 DEG C, and humidity is 80% ± 1%.Condition carry out vulcanization test.Vulcanization front and back aluminium sulfate sail
Every experimental performance index variation of cloth concrete is as shown in table 2.
Each experimental performance variation in 2 aluminium sulfate canvas concrete of table vulcanization front and back
It can be seen that aluminium sulfate canvas coagulation earth removal provided by the invention with good power by the data in table 2
It learns outside performance, also there is good corrosion resistance.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
