In baking process, the temperature control in baking box 100 is between 30 ~ 120 DEG C, and error is at ± 3 DEG C.Due to drying
The degree of drying of roasted journey influences very big to concrete deterioration speed, if the moisture in baking process concrete bodies fails
It is completely dried, degradation speed can be substantially reduced, so the humid control to baking process and the draining before baking process
The control of journey is extremely important, and drainage procedure has to reach the state that bright water is not present in baking box.
Concrete sample 300 was in the said equipment, by 15 days, 45 days, 75 days, 125 days, 155 days, 170 days and 180 days
The erosion in deterioration cycle, concrete crushing strength experiment is carried out by the control cube specimen to every group of different deterioration cycles,
To reflect the changing rule of concrete test block intensity under the different deterioration cycles.Through the sulfate liquor that mass fraction is 7 ± 0.5%
Cube strength test data after drying and watering cycle effect is shown in that Fig. 3, test are 3 test values, and average is three
The average value of test value.
The sulfate liquor that circulation step includes 7 ± 0.5% soaks 15 hours, then normal temperature air-dried 1 hour, then
Toasted 6 hours in 80 DEG C of baking box, normal temperature is cooled down 2 hours（It is cooled to 30 ± 3 DEG C）, such a cycle period is 24 small
When.
Analyzed from Fig. 3, concrete crushing strength can be summarized as with the changing rule in deterioration cycle：1）Deteriorate early stage,
Compression strength value fall is smaller, does not change substantially, 45 deterioration cycle compression strength loss rates only 4.12%；2）Deterioration
To a certain extent（75 days or so）, intensity level declines substantially, wherein 75 days loss of strength rates are 8.82%, 105,125 periodic intensities
Loss late is up to 21.42%, 33.5% respectively；3）Deteriorate the later stage（After 155 days）, concrete crushing strength value fall compared with
Greatly, wherein the intensity rate of descent of 155 days is 42.8%, compression strength rate of descent is up to 74.8% within 180 days.It can be seen that, the drying and watering cycle
Testing equipment can greatly speed up test process.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can
To be improved or converted according to the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Protect scope.
