Product Application:
Used for studying the influence of concrete air-entraining agents on the bubble characteristic parameters of concrete, the relationship between bubble characteristic parameters and material mix ratios, as well as the relationship between bubble spacing coefficient and frost resistance durability indicators.
Execution Standards:
1, "Standard Test Method for Microscopical Determination of Parameters of the Air-Void System in Hardened Concrete" ASTM C457M-16;
2, "Test for Determination of Air Void Parameters in Hardened Concrete" BS-EN-480-11-200;
3, "Test Regulations for Cement and Cement Concrete in Highway Engineering" JTG 3420-2020;
4, "Code for Durability Design of Railway Concrete Structures" TB10005-2010;
5, "Test Regulations for Hydraulic Concrete" SL 352-2020.
Technical Parameters:
1, ※Four testing methods: straight-line method, area method, point-count method, and custom method, truly achieving multi-functionality with one machine;
2, Microscope resolution: <2μm;
3, Microscope magnification 100~200times (adjustable according to user research requirements);
4, Optical system: Original imported 3.0 imaging system, 5-megapixel;
5, ※X and Y axes use magnetic levitation platform with imported grating ruler, movement accuracy <2μm, repeat positioning accuracy 1μm;
6, Chord length test range: ≥1μm, area test range: ≥5μm2;
7, ※X and Y moving platforms are directly driven by motors, without screw transmission, ensuring platform parallelism <2μm during operation;
8, Test time: 5 minutes, may vary depending on test conditions;
9, Specimen size: Maximum 150*150mm, compatible with circular specimens;
10, ※After the test, the generated report automatically completes and inserts the puzzle image on the report's front page without manual intervention;
11, ※X and Y bidirectional displacement platforms, net movement dimensions both greater than 180mm;
12, Measurement data deviation: Air content ≤0.03%, spacing coefficient ≤0.001;
13, Measurement results display: Air content, average bubble chord length, number of bubbles, average bubble radius, average bubble specific surface area, and bubble spacing coefficient; data generated in Excel files as lists and curve graphs;
14, Supports custom paths, allowing manual avoidance of specimen defects to improve test result reliability;
15, Automated measurement system for operation and analysis; users only need to place the sample on the test platform, and the remaining work is automatically completed by the system with report generation;
16, ※Built-in multiple algorithms; area method tests support user-defined ignore area and repair area sizes to enhance test accuracy;
17, Collection and control lines use DB interface mode, more stable and reliable, and convenient for plugging and unplugging;
18, After product upgrade, it can test irregular sample specimens, facilitating on-site testing;
19, Comes with a precision grinding and polishing machine and multiple models of diamond grinding and polishing discs.
