Description
Technical field
The invention belongs to the building materials instrument field, relate to a kind of sulfate dry/wet cyclic test machine, be used for to detect anti-erosion of concrete.
Background technology
As everyone knows, concrete is the building structural materials that consumption is maximum, usable range is the widest.But owing to have a large amount of objectionable constituent and other environmental factors in underground water or the soil, cause concrete to be corroded, make the hydraulic performance declines such as its intensity, permanance and volume stability, cause a large amount of economic losses and casualties.According to domestic and international many studies show that, particularly remarkable to the corrosion that concrete causes with sulfate in these chemical corrosion phenomenons, have a strong impact on the permanance of concrete component.
Concrete sulphate attack is to cause one of major reason of concrete durability destruction, and especially for list structure engineerings such as railway, highways, xoncrete structure can often face the corrosion of sulfate.In the soil, all contain a large amount of sulfate in the alkaline land, underground water, seawater, these sulfate penetrate into inside concrete, a series of physics chemical action can occur in some mineral matters in itself and the concrete, thereby so that concrete structural strength lowers, volume stability descends, and has a strong impact on concrete permanance.Concrete degree of injury is significantly accelerated in the sulphate attack drying and watering cycle that often is coupled, this coupling meeting, and therefore, concrete sulphate attack drying and watering cycle performance is one of important detection index of concrete durability.
Estimate at present the test method of Concrete Resist Reinforcing Sulfate Corrosion and the resisting erosion of sulfate that testing equipment is based on cement more, lack special testing equipment for the Concrete Sulfate Attack drying and watering cycle.For studying concrete sulphate attack test, most researchers adopt the most original a dead lift test specimen mode to carry out.In the cycle period, need three test specimens of carrying, at first concrete sample is taken out from sulfate liquor and dry, then will be transported to and go oven dry in the baking oven, take out at last and put into again sulfate liquor after test specimen cools off and go to soak.So repeatedly, not only experimenter's labour intensity is larger, has consumed than multispecimen when carrying, is difficult to guarantee to accelerate experiment designed dry test specimen and soak time, and is larger on the test error impact.And the carrying meeting causes artificial damage to test specimen repeatedly, especially in the later stage of sulphate attack test, certainly will cause like this test human factor large and the test figure discrete type is large, causes experimental result to lack accuracy and reliability.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, cheap, the sulfate dry/wet cyclic test machine that operating cost is low.
For achieving the above object, technical scheme of the present invention is as follows: a kind of sulfate dry/wet cyclic test machine comprises test specimen case, heating arrangement, condensing unit, control device and air-blast device; Described control device is positioned at the side of test specimen case; Described heating arrangement, condensing unit and air-blast device are positioned at the rear portion of test specimen case; The top of described test specimen case is provided with case lid; Described test specimen case is by two-layer composition up and down; Described test specimen case upper strata is drying baker, and described test specimen case lower floor is soaking box; The bottom of described soaking box is provided with rising pipe.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described case lid is provided with handle.
2, in the such scheme, be equipped with test-piece stand in described drying baker and the soaking box.
3, in the such scheme, the temperature in the described drying baker is 80 ℃, and drying time is 5.5 hours.
4, in the such scheme, be equipped with heating rod in described drying baker and the soaking box.
Because the utilization of the technical program, the present invention compared with prior art has following advantages:
The present invention is simple in structure, makes assembling easily, and cheap, operating cost is low in the use, long service life.And being divided into the top baking oven according to the test specimen box structure, soaking box two parts in bottom are finished immersion and the oven dry of test specimen automatically, cleverly baking oven and soaking box are combined in the test specimen case, the contemporary a dead lift that replaced has been saved manpower, has improved the accuracy of test.
