In order to ensure that the material strength meets the building design life and the structural strength of the building meets the national specifications within the design life, it is necessary to conduct a corrosion resistance test on the cement-based cementitious materials before construction.

[0003] Currently, the corrosion resistance test of building gel materials is mainly carried out by curing the test pieces in a sodium sulfate solution. During the curing period, the test personnel regularly add sodium sulfate solution into the test piece container to maintain the pH value of the erosion solution, and the test personnel need to accurately control the temperature environment of the test pieces. Then, by comparing the flexural strength of the test pieces cured in conventional water, the sulfate erosion resistance of the cementitious materials is evaluated. However, this test method requires the test personnel to monitor at all times, which increases the work intensity of the test personnel, and it is impossible to accurately control the solution concentration, which is extremely likely to cause large fluctuations in the pH value of the solution, affecting the test results.

[0045] As Figure 3 , Figure 4 , Figure 5 and Figure 6 In , Figure 4 and Figure 6 , the holding component 2 includes a fixed sleeve 21 rotatably installed on the detection bin 11 and a second drain pipe 23 penetrating and fixed on the side wall of the detection bin 11.

[0047] As Figure 3 , Figure 4 Figure 5 and Figure 6Among them, the lifting component 3 further includes a first electric push rod 32 fixedly connected through the top of the detection bin 11. The acting end of the first electric push rod 32 is fixedly connected to the cover plate 31. A positioning groove 36 is provided on the hollow disk 34. A limiting frame 35 is fixedly connected to the hollow disk 34. The bottom end of the test block 111 penetrates through the limiting frame 35 and is fitted in the positioning groove 36. The connecting wire of the vibration motor 37 penetrates through the hollow shaft 33 and is electrically connected to the control panel 13. The positioning groove 36 and the limiting frame 35 are used to position the test block 111, and when the first electric push rod 32 expands and contracts, it drives the test block 111 to lift and lower in the placing component 2 for testing.

[0048] Such as Figure 6 , Figure 7 , Figure 9 and Figure 10 Among them, the clamping component 4 includes a lifting plate 41. A threaded rod 44 is rotatably installed on the lifting plate 41. The top end of the threaded rod 44 penetrates through the cover plate 31 and is threadedly connected to the cover plate 31. A rotating disk 45 is fixedly connected to the top end of the threaded rod 44. Two fixed tubes 42 are fixedly connected to the lifting plate 41. Telescopic shafts 43 are slidably arranged in the two fixed tubes 42. The top ends of the two telescopic shafts 43 are fixedly connected to the bottom of the cover plate 31. Two limiting rods 46 are slidably arranged on the lifting plate 41. A contact plate 47 is fixedly connected to the bottom ends of the two limiting rods 46. A baffle 48 is fixedly connected to the two limiting rods 46. The baffle 48 is located above the contact plate 47. When the threaded rod 44 rotates, it drives the lifting plate 41 to lift and lower.

[0049] Such as Figure 9 and Figure 10In the figure, springs 49 are sleeved on both of the two limiting rods 46, and the springs 49 are located between the baffle 48 and the lifting plate 41. Limiting plates 410 are fixedly connected to the tops of both of the two limiting rods 46. Fixed strips 411 are fixedly connected to both sides of the baffle 48 at the bottom of the lifting plate 41. L-shaped rotating plates 412 are rotatably installed at the bottoms of both of the two fixed strips 411, and the bottoms of the two fixed strips 411 are rotatably connected to the outer sides of the corners of the L-shaped rotating plates 412.

Transfer plates 415 are rotatably installed at the ends of the vertical sections of both of the two L-shaped rotating plates 412, and the two transfer plates 415 are located inside the vertical sections of the two L-shaped rotating plates 412. In the initial state, the springs 49 will always push the baffle 48 downward so that the limiting rods 46 extend downward. When the baffle 48 is at the lowest position, the two vertical sections of the L-shaped rotating plates 412 can be flipped outward with the rotation connection points with the fixed strips 411 as the axes, so that the two transfer plates 415 are in an expanded state.

[0050] As Figure 4 、 Figure 5 and Figure 12 In the figure, the driving assembly 5 includes a motor 51 installed at the top inside the detection bin 11 through a fixing member and a plurality of second electric push rods 53 fixed to the top inside the detection bin 11. A gear disc 52 is fixedly connected to the output end of the motor 51. Spline shafts 54 are rotatably installed at the bottoms of the plurality of second electric push rods 53, and the spline shafts 54 are meshed and driven on the side of the gear disc 52. Rubber wheels 55 are fixedly connected to the bottoms of the plurality of spline shafts 54, and the rubber wheels 55 can descend and be attached to the hypotenuse of the transmission ring 26. When the gear disc 52 rotates, it drives the plurality of spline shafts 54 to rotate. When the second electric push rods 53 extend, the rubber wheels 55 can descend and be attached to the inclined surface of the transmission ring 26 to drive the transmission ring 26 to rotate.

[0051] As Figure 11 In the figure, the detection assembly 6 includes a detection rod 61 penetrating and fixed on the cover plate 31. A detection electrode 63, a through hole 62 and a temperature sensing module 64 are arranged at the bottom of the detection rod 61. A hose 19 is fixedly connected to the top of the detection rod 61 at the opening of the through hole 62. The end of the hose 19 is connected to the liquid outlet end of the delivery pump 15. An electromagnetic flow sensor 110 and a first solenoid valve 112 are installed on the hose 19. The temperature sensing module 64 is used to detect the temperature of the solution in the device, and the detection electrode 63 is used to detect the pH value of the solution. When the first solenoid valve 112 is opened, sodium sulfate stock solution can be added into the device through the through hole 62, and the electromagnetic flow sensor 110 is used to detect the amount of the injected solution, so as to adjust the solution environment in the device.

[0052] During operation, since the existing test method requires testers to monitor at all times, it increases the work intensity of the testers. Moreover, it is impossible to accurately control the solution concentration, which is extremely likely to cause large fluctuations in the pH value of the solution, affecting the test results. At the same time, the testers directly contacting sulfuric acid reagents are extremely likely to be in danger, increasing the risk of the testers being eroded by the reagents. In this solution, by injecting sodium sulfate solutions or distilled water with different concentrations into multiple containing components 2, and cooperating with controlling the extension of the first electric push rod 32 to drive the cover plate 31 to lift. When the cover plate 31 lifts, it drives the hollow disk 34 to lift out of the fixed sleeve 21 through two hollow shafts 33. Then, the test block 111 to be detected is placed in the limit frame 35, and its bottom end is fitted into the positioning groove 36. Then, the rotating disk 45 is rotated. When the rotating disk 45 rotates, it can drive the threaded rod 44 to rotate. Under the limitation of the fixed pipe 42 and the telescopic shaft 43, when the threaded rod 44 rotates, it will drive the lifting plate 41 to descend. And when the lifting plate 41 descends, it will drive two adapter plates 415 to descend. When the abutting plate 47 abuts against the top of the test block 111, the threaded rod 44 is continuously rotated. At this time, the lifting plate 41 continues to descend, and at the same time, it will squeeze the spring 49 to contract downward. After the spring 49 contracts, the limiting rod 46 will extend towards the lifting plate 41, thereby reducing the distance between the baffle plate 48 and the lifting plate 41. And under the support of the fixing strip 411, the baffle plate 48 will drive the horizontal section of the L-shaped rotating plate 412 to flip upward through the connecting plate 414, and make the connecting plate 414 slide and extend in the limiting groove 413. When the horizontal section of the L-shaped rotating plate 412 flips upward, it will drive the vertical section of the L-shaped rotating plate 412 to flip inward, thereby driving two adapter plates 415 to first contract inward and fit on the two side walls of the test block 111 to complete the clamping and fixing of the test block 111. Then, control the first electric push rod 32 to contract to drive the cover plate 31 to descend, thereby driving the test block 111 fixed under the cover plate 31 to descend into the rotating sleeve 22;

[0053] Multiple detection components 6 respectively detect the pH value changes of the solutions in multiple containing components 2, and the temperature sensing module 64 detects the corresponding solution temperature. And when the pH value change of the solution is detected, after controlling the delivery pump 15 to be turned on, the sodium sulfate stock solution in the storage tank 14 will be pumped into the device, and cooperate with controlling the corresponding first solenoid valve 112 to be opened. After the first solenoid valve 112 is opened, the sodium sulfate stock solution will be injected into the corresponding containing component 2. When the sodium sulfate stock solution is injected, the electromagnetic flow sensor 110 detects the amount of the sodium sulfate stock solution injected. After the injection amount of the sodium sulfate stock solution reaches the standard, control the first solenoid valve 112 to be closed in time, thereby controlling the injection amount;

[0054] Timing is carried out in accordance with test blocks 111 with different ratios or different test environments, and recording and control are performed through the control module 12 and the control panel 13. According to the need, the corresponding second electric push rod 53 is controlled to extend. When the second electric push rod 53 extends, it drives the spline shaft 54 to descend. When the spline shaft 54 descends, it drives the rubber wheel 55 to descend and make it fit on the inclined side of the transmission ring 26. In cooperation with the control of the driving of the motor 51, when the motor 51 operates, it drives the gear disk 52 to rotate. When the gear disk 52 rotates, it drives the spline shaft 54 to rotate. Then, the transmission ring 26 is driven to rotate through the corresponding rubber wheel 55, and then the corresponding rotating sleeve 22 is driven to rotate. When the rotating sleeve 22 rotates, the solution inside it is stirred by the stirring blades 27 on the inner wall to simulate the water flow effect in the actual environment, ensure the uniformity of the solution components around the specimen, and at the same time can also simulate the water flow effect in the actual environment, and can be quickly and evenly dispersed when adding the sodium sulfate stock solution, and ensure the consistency of temperature, thereby ensuring the accuracy of the test curing environment simulation data. And the temperature of the solution in the rotating sleeve 22 can be increased by controlling the corresponding heating sheet 18 to simulate different environmental temperatures. And by controlling the corresponding vibration motor 37 to operate to generate vibration, the vibration is transmitted to the test block 111 fixed on it through the hollow disk 34, and then the vibration frequency and amplitude are adjusted according to the test requirements to simulate the vibration effect received by the concrete structure in the actual project, and more truly reflect the corrosion resistance of the concrete binder under complex working conditions. In cooperation with simulating different test environments, the sulfate erosion resistance of the gel material is evaluated by comparing the flexural strength retention rate of the stones soaked in different test environments;

[0055] The test data is controlled and displayed through the control module 12 and the control panel 13, and the curing environments in multiple storage components 2 can be independently controlled to achieve the automatic control of the test;

[0056] The cooperation achieves the function of automatic control of the curing test, effectively reduces the risk of injury to the test personnel directly contacting dangerous liquids, and can automatically control the solution concentration according to the test data, effectively ensuring the accuracy of the test data.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
