325,000lbf Auto Concrete Compression and Flexural Machine

Gilson AC-325, 325K Automatic Concrete Compression & Flexural Machine

AC-325 Series Fully Automatic Concrete Compression Machines are advanced testing systems engineered to provide precise, reliable results for concrete compression and flexural strength testing. Designed with state-of-the-art technology, these machines are ideal for laboratories, construction professionals, and researchers aiming for efficient, error-free testing that complies with stringent industry standards.

Unmatched Accuracy and Efficiency

The AC-325 Series is pre-configured to test the compressive strength of 6x12in (152x305mm) concrete cylinders, supporting loads up to 325,000lbf (1,446kN) and a maximum pressure of 9,200psi (63.4mPa). Equipped with advanced air-cushion technology and a hydraulic system, this machine ensures precise, repeatable load application. The automated test cycle requires minimal operator input—just press a single button on the intuitive touchscreen controller to initiate testing.

Advanced Features for Seamless Operation

• Automated Testing Process: The machine handles specimen contact, pre-loading, load rate, break detection, and piston reset automatically. This eliminates errors caused by variations in load rates or manual procedures.
• Intuitive Touchscreen Interface: Setup is simple and menu-driven. Operators can select test methods, enter specimen data, and monitor real-time metrics like force, stress, and load rate.
• Real-Time Data Visibility: View load vs. time or stress vs. strain graphs during testing for detailed insights. The system also offers notifications and displays diagnostics for troubleshooting.
• Comprehensive Data Management: USB, LAN, and Wi-Fi connectivity allow seamless data transfer. Export test results instantly via USB drive or network for reporting and analysis. Testing laboratory and client information is stored for error-free documentation.

Enhanced Safety and Durability

Safety and reliability are at the forefront of the AC-325 Series design. The rugged, welded steel frame exceeds ACI 363 standards for rigidity, ensuring long-term durability. Additionally, the machine is equipped with multiple safety features, including:

• Emergency-stop button
• Hydraulic safety relief valve
• Piston over-travel limit switch
• Transparent fragment guard doors

The integrated electric motor and variable-speed hydraulic pump operate smoothly and quietly, maintaining consistent pressure and extending the life of the hydraulic components. The top-mounted piston design protects the loading system from debris, reducing wear and maintenance needs.

Adaptability for a Range of Tests

The AC-325 Series is highly versatile, offering capabilities beyond standard compression tests. The base model can be upgraded with accessories to perform additional testing, including split tensile and flexural strength. For specialized testing, factory-modified models like the AC-325M and AC-325MR are available, equipped for ASTM C469 modulus of elasticity (MOE) tests and Poisson’s ratio measurements on 4 or 6in cylinders. These models use advanced components, including LVDT inputs, and are compatible with Compressometer and Compressometer/Extensometer fixtures (sold separately).
