China Bubble Spacing Coefficient Tester 457

Product Usage:

Used to study the influence of concrete air entraining agents on the characteristic parameters of concrete bubbles, the relationship between bubble characteristic parameters and material ratios, and the relationship between bubble spacing coefficient and frost resistance durability indicators.

Execution standards:

1. ASTMC457M-16, Test for Pore Analysis of Hardened Concrete;

2. Test for Determination of Pore Gap in Hardened Concrete BS-EN-480-11-200;

3. Test Code for Cement and Cement Concrete in Highway Engineering JTG 3420-2020;

4. Code for Durability Design of Railway Concrete Structures (TB10005-2010);

5. Test Code for Hydraulic Concrete (SL 352-2020).

Technical parameters:

1. ※ Four testing methods: straight wire method, area method, point method, and custom method, truly achieving one machine with multiple uses;

2. Microscope resolution:<2μ M;

3. Microscope magnification of   100-200 times (adjustable according to user research requirements);

4. Optical system: Original imported 3.0 imaging system, 5 million pixels;

5. ※ The X and Y axes are equipped with magnetic levitation platforms and imported grating rulers, with a movement accuracy of<2μ m. Repetitivepositioning accuracy 1μ M;

6. Chord length test range: ≥ 1μ m. Area testing range: ≥ 5μ M2;

7. The X and Y mobile platforms are both directly driven by motors without screw transmission links, ensuring a parallelism of less than 2um during platform operation;

8. Test time: 5 minutes, depending on the test conditions;

9. Sample size: maximum 150 * 150mm, compatible with circular specimens;

10. After the experiment, the generated report will automatically complete the puzzle and insert it into the report homepage, without the need for manual intervention;

11. The X and Y bidirectional displacement platforms have a net movement size greater than 180mm;

12. Measurement data deviation: gas content ≤ 0.03%, spacing coefficient ≤ 0.001;

13. Measurement results display: gas content, average chord length of bubbles, number of bubbles, average radius of bubbles, average specific surface area of bubbles, and bubble spacing coefficient. The data is generated in an Excel file as a list and curve graph;

14. Support custom paths, which can artificially avoid detecting defects in test specimens and improve the reliability of test results;

15. An automated measurement system for operation and analysis, where users only need to import samples into the testing platform, and the remaining work is automatically completed and reports are generated by the system;

16. ※ Built in multiple algorithms, the area method experiment supports users to customize the size of ignoring and repairing areas, increasing the accuracy of the experiment;

17. The acquisition line and control line both adopt DB socket mode, which is more stable, reliable, and convenient to plug and unplug;

18. After upgrading the product settings, irregular sample specimens can be tested, making it convenient for on-site testing;

19. Equipped with precision grinding and polishing machines and multiple models of diamond grinding and polishing discs.
