The fully automatic intelligent sealed concrete impermeability tester is mainly used to test the impermeability performance of concrete. By simulating the impermeability ability of concrete under water pressure, the quality of concrete can be evaluated. The following are the operating procedures for the instrument:
1. Preparation work
Check the equipment: Ensure that all components of the instrument are intact and undamaged, and check if the instrument power supply is working properly.
Calibration instrument: If not used for a long time or before use, calibrate the instrument to ensure its accuracy.
Cleaning the instrument: Before operation, clean all contact parts of the instrument to avoid contamination that may affect the test results.
2. Sample preparation
Concrete sample requirements: According to the testing standards, the sampled concrete specimens should meet the specified size requirements (generally 100 × 100 × 400mm or other standard sizes).
Test piece processing: Ensure that the surface of the test piece is smooth and flat, without cracks or defects. If there are oil stains or impurities on the surface of the test piece, it must be cleaned first.
Curing samples: The specimens should be cured under standard curing conditions until the required age is reached during testing.
3. Sample installation
Sealing: Place the concrete specimen into the testing slot of the instrument to ensure good sealing and prevent moisture leakage from affecting the test results.
Connect the test pipeline: According to the design of the instrument, correctly connect the water pipe to the specimen to ensure stable water pressure during testing.
4. Set test parameters
Select testing mode: Select the anti-seepage testing mode according to standard requirements, set the testing time and water pressure.
Water pressure setting: Set an appropriate water pressure according to the test requirements, usually gradually increasing until reaching the specified standard pressure (usually 0.6 MPa or 1.0 MPa, etc.).
Temperature control: Ensure that the testing environment temperature meets the requirements of concrete impermeability testing, and avoid excessive temperature differences that may affect the testing.
5. Start testing
Start the instrument: Start the fully automatic intelligent sealed concrete impermeability meter, and the instrument will automatically apply pressure and maintain it at the set water pressure conditions for the specified time.
Monitoring during the testing process: Observe the changes in water pressure during the testing process to ensure that the water pressure is stable and meets the standard requirements. Instruments usually display real-time data such as water pressure and permeation time.
6. End the test and record the results
Automatic determination: After the test is completed, the instrument will automatically determine the impermeability performance of the concrete specimen and generate a report.
Result recording: Record the specific values of the test, such as water infiltration time, water infiltration amount, etc., and determine the impermeability level of the specimen based on its permeability.
Result output: Output the test report through the instrument's built-in software system. The report includes key data such as water pressure, testing time, and seepage volume, and provides an evaluation of the anti-seepage level.
7. Clean the instrument
Disassemble the sample: After the test is completed, take out the concrete specimen.
Cleaning equipment: Use clean water to clean the testing tank and testing pipeline, avoiding the accumulation of scale or other substances that may affect the next test.
Storage: Keep the instrument clean and store it as required, and regularly check the operating status of the instrument.
8. Data processing and analysis
Data recording: Ensure that each test result is recorded in detail, especially the infiltration time and water pressure value.
Result analysis: By comparing the test results of multiple samples, evaluate whether the impermeability performance of concrete meets the design requirements.
Notes:
Environmental requirements: The testing environment should maintain stable temperature and humidity to avoid extreme temperature or humidity changes that may affect the test results.
Equipment maintenance: Regular maintenance and upkeep of instruments, especially inspection of electrical components, seals, and water pipelines, to prevent equipment aging or malfunction.
Personnel training: Operators should receive professional training to ensure they are proficient in the operating procedures of the instrument.
By following the above operating procedures, it can be ensured that the use of the fully automatic intelligent sealed concrete impermeability tester is more accurate and efficient, thereby obtaining reliable results for concrete impermeability testing.
