Description

Technical Field

[0001] The present disclosure relates to the technical field of concrete durability testing, and in particular to an integrated concrete carbonization tester. Background Art

[0002] When concrete is exposed to air, CO2 in the air penetrates into the surface and micropores of concrete, and reacts with Ca(OH)2 and alkaline gel in concrete in the presence of water to generate CaCO3 and H2O, which is the carbonization of concrete. Concrete carbonization will reduce the alkalinity of concrete and increase the number of hydrogen ions in the concrete pore solution. In addition, the intrusion of external water will weaken the protective effect of concrete on steel bars. Therefore, the test of concrete carbonization depth is an extremely important measurement item.

[0003] Concrete carbonation test is an important means to evaluate the durability of concrete, and the rebound method is usually used for testing. This method uses a rebound hammer to measure the concrete surface to evaluate the hardness and carbonation degree of the concrete. During the test, it is necessary to first use a chisel or drill to chisel out a notch on the concrete surface to remove floating dust and provide a good reaction surface. Subsequently, phenolphthalein indicator is sprayed to show color differences when the carbonation depth changes. Finally, the notch depth is tested with a rebound hammer to infer the degree of carbonation of the concrete.

[0004] However, the existing concrete carbonization test methods have the following problems:

[0005] (1) The equipment is bulky and inconvenient to carry: When conducting carbonization tests, it is necessary to carry a variety of tools to complete different operations. The equipment is numerous and inconvenient to carry, especially when the on-site conditions are limited. The operation is inconvenient, which increases the complexity and physical burden of the operation.

[0006] (2) Complicated operation: The operation process includes multiple steps, such as chiseling out gaps, cleaning up loose dust, spraying phenolphthalein indicator, etc., which rely heavily on manual operation. The process is complicated and time-consuming. Operations such as drilling holes and cleaning up loose dust require personnel to have certain skills and experience. For non-professional operators, test errors caused by improper operation are prone to occur.

[0007] (3) High requirements for surface cleanliness: The test accuracy is greatly affected by the cleanliness of the concrete surface. If the floating dust on the notch is not thoroughly cleaned, it may lead to errors in the test results.

[0008] (4) Sensitive to environmental conditions: In actual construction sites, the test method is often affected by factors such as environmental humidity and temperature. This test method is relatively sensitive to environmental humidity, temperature and other conditions. Especially in a humid environment, moisture is easily attached to the surface of the concrete, affecting the accuracy of the test results.

[0009] In order to solve the above problems, an integrated concrete carbonation tester was designed. Summary of the invention

In this way, additional power support can be provided to the tester, and the power consumption of the power supply 27 can be effectively slowed down when the device works for a long time.

[0105] In one example, the power generation device is a wind power generation device, which is connected to the cleaning component. The wind power generated by the fan 14 drives a small generator in the wind power generation device to work, thereby providing auxiliary power for the equipment.

[0106] Optionally, the wind power generation device adopts high-sensitivity turbine technology to achieve stable current generation, reduce the burden on the power supply 27, and extend the working time of the equipment.

[0107] In another example, the power generation device is a solar panel, and the solar panel can be detachably mounted on the surface of the housing 1 .

[0108] In the first embodiment of the present disclosure, see Figures 1 to 5 The working process of the integrated concrete carbonization tester is briefly described as follows:

[0109] When used, the present disclosure includes the following steps:

[0110] Equipment preparation:

[0111] (1) Check whether each module of the tester is working properly;

[0112] (2) According to the actual strength and hardness of the concrete specimen, select a drill bit 3 of appropriate specifications, and adjust the hardness and size of the drill bit as needed to ensure that the drilling depth is appropriate to avoid affecting the subsequent test results;

[0113] (3) Place the device on the sample surface and calibrate the automatic measurement reference point.

[0114] To test:

[0115] (1) Use the drilling assembly in the tester to drill a fixed depth on the surface of the sample. The drilling angle is automatically adjusted by the equipment to be perpendicular to the surface of the sample to ensure that the drilling depth reaches the set standard. Keep the drill bit stable during drilling to avoid deflection. After the drilling is completed, check whether the hole depth meets the test requirements;

[0116] (2) After the drilling is completed, start the cleaning component to clean the dust and debris in the drilling area. If there is a lot of dust or moisture on the surface of the test piece, use the hot air position of the fan 14 to dry it to ensure that the surface of the test piece is clean and dry, thereby ensuring the accuracy of the test results;

[0117] (3) Check the test surface condition to ensure that there is no residual moisture, dust or impurities on the test surface and that the test piece surface is flat and clean to facilitate the smooth progress of subsequent test operations;

[0118] (4) Open the drawer 23, take out the hidden spray bottle therein, and spray an appropriate amount of pre-configured indicator solution into the drilled hole. The indicator solution is a phenolphthalein solution. The indicator solution should be sprayed evenly to ensure that the entire hole is filled. Wait for a while and observe the color interface formed by the solution and the concrete surface.

[0119] (5) Place the housing 1 vertically on the test piece surface through the reference rod, keep the reference rod perpendicular to the test surface, and ensure that the reference rod is stable and will not affect the test data;

[0120] (6) using a laser rangefinder 2 to ensure that the laser beam of the laser rangefinder 2 accurately points to the color interface, that is, the location where the indicating solution and the concrete surface intersect, and using the laser rangefinder 2 to collect carbonization depth data;

[0121] (7) Read the measurement results according to the display interface of the laser rangefinder 2. The display screen 29 displays the depth data of the carbonized layer of the concrete. The user can record the relevant data as needed.

[0122] Test results:

[0123] (1) To ensure the accuracy of the test results, multiple different test points are selected for measurement on a batch of concrete specimens, and each test point is tested three or more times. The tester completes no less than 20 tests and the average value is taken as the final measurement result.

[0124] (2) The test results show that the measurement error of the tester does not exceed ±0.5mm, which meets the accuracy requirements.

[0125] Data Export:

[0126] (1) Use a data cable to connect the tester to the computer via the USB interface and ensure a stable connection;

[0127] (2) Open the relevant test software or file manager on the computer and find the test data file generated by the device. The data is saved in txt format and the user can export it to the computer;

[0128] (3) Import the exported test data in txt format into Excel for further analysis, generate charts or perform data processing, and perform statistics and comparison on the test data as needed to obtain the final result of carbonization depth.

[0129] In the second embodiment of the present disclosure, see Figures 1 to 5 , the carbonation depth of concrete under different environmental conditions was measured:

[0130] In order to verify the adaptability of the tester under various environmental conditions, the tester was tested under high humidity (85% RH) and low temperature (5°C) conditions.

[0131] Test steps:

[0132] (1) Carbonation tests were performed on concrete samples with the same mix ratio under two environmental conditions:

[0133] (2) Each group of tests was performed 10 times, and the carbonization depth data was recorded and compared with the manual measurement results.

[0134] Test results:

[0135] The average measurement error of the tester in the two environments is ±0.7mm, and the consistency with the manual measurement result is 98%. The display screen 29 can still maintain good performance under extreme environmental conditions.
