325,000lbf Automatic Concrete Compression, Flexural, MOE

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

AC-325 Series Fully Automatic Concrete Compression Machines

The AC-325 Series Fully Automatic Concrete Compression Machines are cutting-edge solutions designed for precision compression strength testing of concrete specimens. These machines are ideal for testing 6x12in (152x305mm) concrete cylinders with a maximum strength of up to 9,200psi (63.4mPa). Equipped with advanced features and built to meet industry standards, the AC-325 series delivers accurate, repeatable results while ensuring user safety and convenience.

Key Features and Benefits

1. Intelligent Automation: The machine operates with minimal operator input. Testing begins with the press of a single button on the menu-driven touchscreen controller, ensuring ease of use and increased productivity. Automated cycles eliminate variations in load rates and test procedures, guaranteeing accurate and consistent results.

2. Compliance with Standards: The AC-325 series strictly adheres to ASTM, AASHTO, BS 1610, and BS 1881 specifications, making it suitable for both research and commercial lab environments.

3. Real-Time Data Display: During testing, force, stress, and rate of load are displayed simultaneously on the controller. Real-time graphs for load vs. time or stress vs. strain are also available for enhanced analysis.

4. Advanced Data Management: The machine includes USB, LAN, and Wi-Fi connectivity, enabling seamless data transfer, immediate printing, or saving results via a USB drive. Testing laboratory details, sample ID, and client information are stored for error-free reporting.

5. Enhanced Safety: Operator safety is prioritized through features like an emergency stop button, a hydraulic safety relief valve, a piston over-travel limit switch, and see-through fragment guard doors.

6. Next-Generation Drive System: The integrated electric motor and hydraulic pump operate with variable speeds, ensuring precise pressure regulation. This design reduces noise, prevents overheating, and extends the hydraulic system's service life.

7. Durable Construction: With a rugged, welded steel frame rated at 325,000lbf (1,446kN) and exceeding ACI 363 requirements, the AC-325 is designed for long-term reliability. The piston is mounted at the top of the frame, protecting the hydraulic system from debris during tests.

8. Versatile Testing Capabilities: The AC-325 models can perform compression, flexural, and splitting tensile strength tests. They can be enhanced with accessories to perform additional testing, such as determining the modulus of elasticity (MOE) and Poisson’s ratio.

Special Models for Advanced Applications

• AC-325M and AC-325MR: These factory-modified versions include additional features like an optional proportional valve for controlled piston retraction and inputs for LVDT sensors. These models are tailored for advanced testing, including ASTM C469 modulus of elasticity (MOE) and Poisson’s ratio measurements. They are compatible with accessories like compressometers and compressometer/extensometer fixtures for precise deformation analysis (sold separately).
