Abstract
The invention relates to a corrosion-resistant cement fence. A finished product is prepared by the following steps: weighing cement, sand, fly ash, blast furnace slag, silica fume, a water reducer and an expanding agent in proportion, mixing the above ingredients and water to prepare slurry, pouring and maintaining. In the invention, silica fume has smaller volume, and silica fume and cement form a compact structure; and after the use of the expanding agent, internal capillary-size pores are further reduced so as to prevent corrosive air or a corrosive liquid from entering and preventing damage of a corrosion source to the surface layer and inside of the cement fence. By cooperation with coating of the cement fence, corrosion resistance of the cement fence is raised, service life is longer, and cost increases little. The cement fence of the invention is a novel product which is worthy of promotion.
Description
Technical field
The invention belongs to the corrosion-resistant technical field of enclosure, especially a kind of corrosion-resistant enclosure and preparation method thereof.
Background technology
Enclosure is called again cement artistic fence, Cement guard bar, cement hurdle, and its shock resistance is good, time prepared by fence, can adopt, compare with iron skill product to form the quality of granite, white marble, copper modelled after an antique with different applications simultaneously, enclosure dimensionThe expense of protecting is low, not fragile, can not get rusty, so enclosure has sturdy and durable, elegant in appearance, inexpensive advantage.At present, enclosure taking cement, sand as primary raw material, taking hand-drawn wire as skeleton, but in coastal area or acid rain environmentHeavily contaminated city in, enclosure also there will be the problem of frequent damage, main cause is that in air or rainwater, salt content is higher,After Long Term Contact enclosure, cause the loosening of structure, the corrosion on top layer, external producer develops high performance corrosion-resistant cement materialMaterial, but cost is higher when actual use, is unfavorable for large-scale popularization.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide science collocation, acidproof salt performance good, cost suitable onePlant corrosion-resistant enclosure.
The technical scheme that the present invention takes is:
A kind of corrosion-resistant enclosure, is characterized in that: comprise the following component of mixing by weight:
And, comprise the following component of mixing by weight:
And described flyash specific area is 450 square metres/kilogram.
And described blast-furnace cinder specific area is 400 square metres/kilogram.
And described water reducer is polycarboxylate high performance water-reducing agent.
Another object of the present invention is to provide a kind of preparation method of corrosion-resistant enclosure, it is characterized in that: comprise following stepRapid:
(1) get cement, sand, flyash, blast-furnace cinder, silicon ash, water reducer and swelling agent by weighing balance, for subsequent use;
(2) cement is put into mixer, the stirring that adds water, continues to add flyash, blast-furnace cinder, continues to stir;
(3) continue to add silicon ash, continue to stir 10 minutes;
(4) add water reducer and swelling agent, stir and build after 20 minutes;
(5) technology carries out making finished product after maintenance routinely.
Advantage of the present invention and good effect are:
In the present invention, get cement, sand, flyash, blast-furnace cinder, silicon ash, water reducer and swelling agent by weighing balance, by suitableOrder is mixed each component to make slurry with water, builds rear maintenance and makes finished product. Silicon ash volume is less, forms fine and close knot with cementStructure, swelling agent has further dwindled inner capillary porosity after using, and stops corrosion air or corrosive liquid to carry out inside, stopsSource of corrosion is to enclosure top layer and inner destruction, and the two and the outer field application of enclosure cooperatively interact, and have improved cement and have enclosedThe resistance to corrosion on hurdle, longer service life, cost increases seldom, is a kind of novel product being worthy to be popularized.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can notLimit protection scope of the present invention with following embodiment.
A kind of corrosion-resistant enclosure, innovation of the present invention is: comprise the following component of mixing by weight:
Preferred scheme is: comprise the following component of mixing by weight:
Wherein, described flyash specific area is 450 square metres/kilogram. Described blast-furnace cinder specific area be 400 square metres/Kilogram. Described water reducer is polycarboxylate high performance water-reducing agent.
Another object of the present invention is to provide a kind of preparation method of corrosion-resistant enclosure, it is characterized in that: comprise following stepRapid:
(1) get cement, sand, flyash, blast-furnace cinder, silicon ash, water reducer and swelling agent by weighing balance, for subsequent use;
(2) cement is put into mixer, the stirring that adds water, continues to add flyash, blast-furnace cinder, continues to stir;
(3) continue to add silicon ash, continue to stir 10 minutes;
(4) add water reducer and swelling agent, stir and build after 20 minutes;
(5) technology carries out making finished product after maintenance routinely.
Take each component by metering, then water and build up crossbeam by preparation method, maintenance, after 30 days, is dried 20 hours in drying box,Put into concentration and be 0.5% salt solution and soak 5 months, the more unsoaked test specimen of intensity reduces by 0.4%, but surfacing, after weighingWeightlessness 0.01%, strength decreased 1% after the test specimen of regular convention formula soaks, weightless 0.2%.
In the present invention, get cement, sand, flyash, blast-furnace cinder, silicon ash, water reducer and swelling agent by weighing balance, by suitableOrder is mixed each component to make slurry with water, builds rear maintenance and makes finished product. Silicon ash volume is less, forms fine and close knot with cementStructure, swelling agent has further dwindled inner capillary porosity after using, and stops corrosion air or corrosive liquid to carry out inside, stopsSource of corrosion is to enclosure top layer and inner destruction, and the two and the outer field application of enclosure cooperatively interact, and have improved cement and have enclosedThe resistance to corrosion on hurdle, longer service life, cost increases seldom, is a kind of novel product being worthy to be popularized.
