AC-250 Series Fully Automatic Concrete Compression Machines

The AC-250 Series Fully Automatic Concrete Compression Machines are engineered for precision, reliability, and ease of use, making them an essential tool for material testing laboratories. Designed to perform comprehensive strength tests on concrete cylinders, beams, cubes, cores, and other sample types, these machines provide fully automated testing with minimal operator input. From specimen preparation to data collection, the AC-250 streamlines the entire testing process while ensuring compliance with ASTM, AASHTO, and other industry standards.

Key Features:

• Advanced Automation: The AC-250 series features a touchscreen controller that initiates a fully automated test cycle with a single button press. The system controls specimen contact, pre-loading, load rate, break detection, and piston return, eliminating variations in load rates and test procedures for consistent and accurate results.
• Comprehensive Data Collection: Force, stress, and load rate are displayed in real-time during testing. Users can also view live load vs. time or stress vs. strain graphs. Test data is easily transferred via USB, LAN, or Wi-Fi for instant reporting and analysis.
• Diagnostics and Safety: Built-in diagnostics monitor the emergency stop button, hydraulic system, pressure transducer, and other components. Any fault condition is immediately flagged, preventing testing until resolved. Safety features include an emergency-stop button, hydraulic safety relief valve, over-travel limit switch, and fragment guard doors.
• Energy-Efficient Drive System: The integrated electric motor and hydraulic pump operate at variable speeds to maintain precise pressures, reducing noise, heat, and wear on components. This next-generation system extends the machine’s service life while delivering consistent performance.
• Exceptional Build Quality: The rugged, welded steel frame exceeds ACI 363 requirements, ensuring superior rigidity and durability. The piston is mounted on top of the frame to prevent damage from test debris, minimizing long-term wear on the hydraulic system.

Testing Capabilities:

The AC-250 Series can perform compressive, flexural, and splitting tensile strength tests, as well as modulus of elasticity (MOE) and Poisson’s ratio measurements with the appropriate accessories. These capabilities make it a versatile solution for various testing needs across construction and engineering industries.

• Compression Strength Testing: Designed for 6x12in (152x305mm) concrete cylinders, with unbonded neoprene capping pads and steel retainers.
• Flexural Strength Testing: Determine the flexural properties of concrete under load.
• ASTM C469 Modulus of Elasticity and Poisson's Ratio: The AC-250M and AC-250MR models include modified manifolds and optional proportional valves for precise piston retraction, offering advanced testing capabilities for MOE and Poisson's ratio determinations on 4 or 6in cylinders.

Additional accessories, such as compressometers and extensometers, are available for enhanced test configurations.

Enhanced Usability:

Selection of test parameters, sample types, and testing methods is simplified through the intuitive, menu-driven touchscreen controller. This user-friendly interface reduces operator errors while improving test productivity. Laboratory and client information, as well as sample IDs, can be stored for streamlined reporting.

Compliance with Testing Standards:

The AC-250 Series meets or exceeds the following standards:

• AASHTO T 22
• ASTM C 39
• ASTM E 4
• BS 1610
• BS 1881

Included Items:

• 250,000lbf Automatic Concrete Compression Machine (110V, 60Hz or 230V, 50Hz)
• 6x12in Cylinder Test Set for use with Unbonded Caps
• Mounting stand
