AC-325 Series Fully Automatic Concrete Compression Machines are supplied ready for compression strength testing of 6x12in (152x305mm) concrete cylinders up to 9,200psi (63.4mPa) with user-supplied unbonded neoprene capping pads and steel retainers. The standard frame may be outfitted with the accessories listed below to accommodate additional testing.

Minimal operator input is required—an automated test cycle is initiated with a single button on the touchscreen controller. Variations in load rates and test procedures are eliminated, ensuring accurate, repeatable, and documented results, strictly conforming to ASTM, AASHTO, and other testing specifications. The machine controls specimen contact, pre-loading, rate of load, break detection, data collection, and return of the piston to the home position following specified requirements for the selected test method.

Selection of the test method, sample type, specimen data, and test parameters are made on the touchscreen of the controller. Force, stress, and rate of load are displayed simultaneously during a test, and real-time load vs time or stress vs strain graphs can also be shown. Load rate and applied force are precisely regulated by feedback during sample loading. USB and LAN ports, along with Wi-Fi capability, allow immediate printing of tests, or easy data collection and transfer to the user’s PC for reporting of results using a USB flash drive.

A menu button prints each test or transfers a summary of the test data. Testing laboratory, sample ID, and client information are stored for error-free reporting and distribution. The status of the emergency-stop button, drive system, data communication, pressure transducer, and over-travel limit switch are all displayed on the diagnostics screen. An indication of a fault condition in any of the systems must be resolved before testing can proceed.

The integrated electric motor and the hydraulic pump operate at variable speeds to achieve and maintain required pressures based on loading program demands. This state-of-the-art and energy-efficient drive system is dramatically quieter, eliminates pressure variations from over-heated oil, and extends the service life of the hydraulic components.

The rugged, welded steel frame has a total capacity of 325,000lbf (1,446kN) and exceeds ACI 363 requirements for system rigidity. Excessive long-term wear to the hydraulic loading system is prevented by mounting the piston in the top of the frame, where it is unaffected by accumulated test debris. An emergency-stop button, hydraulic safety relief valve, piston over-travel limit switch, and fragment guard door ensure safety to the operator while running tests.

AC-325 models are standard load frames equipped to run compression and flexural testing on concrete specimens. These models can be outfitted with accessories to accommodate additional testing.

AC-325M and AC-325MR models are special factory-modified models that are outfitted with a different manifold, optional proportional valve for controlled piston retraction, and either one or two LVDT inputs required to determine ASTM C469 modulus of elasticity (MOE), or MOE and Poisson’s ratio on 4 or 6in (101 or 152mm) cylinders. These modified models are also capable of determining compressive, flexural, and splitting tensile strength tests by using the same component sets (based on test type and frame capacity) as the standard forms. Compressometer and Compressometer/Extensometer testing fixtures for MOE and Poisson’s ratio testing must be purchased separately.
