300,000lbf Automatic Concrete Compression, Flexural and MOE

Gilson 300,000lbf Rigid Frame (RF) Series Automatic Concrete Compression Machines

The Gilson 300,000lbf Rigid Frame (RF) Series Automatic Concrete Compression Machines are designed for laboratories with heavy daily testing demands and the need for reliable, repeatable results. Incorporating advanced engineering, these machines combine precision, efficiency, and durability to meet the rigorous requirements of high-strength concrete testing. Built with highly rigid load frames, they exceed ACI 363 recommendations for enhanced performance, durability, and safety.

Whether you're testing standard concrete cylinders, flexural beams, or high-strength mixes, the RF Series ensures accurate and consistent test results. Equipped with state-of-the-art automation, these machines streamline the entire testing process, from setup to data reporting, making them ideal for high-volume labs.

Key Features & Benefits

• Highly Rigid Load Frames: The robust frame construction minimizes elastic deformation during loading cycles, extending the service life of machine components and ensuring consistent performance. The lateral stiffness also helps reduce errors from minor sample misalignments, delivering more accurate results.
• Advanced Hydraulic System: The bottom-mounted hydraulic cylinder applies upward loading force, featuring a flexible sleeve for dust protection. The hydraulic components are optimized for longevity and precision, unaffected by oil temperature changes or other variables.
• User-Friendly Automation: With minimal operator input, the touch-screen controller simplifies testing. Enter specimen data, select the test type, and position the sample—then start with the push of a button. For multiple samples of the same type, repetitive data entry is eliminated.
• Real-Time Data Display & Collection: During testing, force, stress, and load rates are displayed continuously, with real-time graphing of load vs. time or stress vs. strain. Data is easily transferred via USB, LAN, or Wi-Fi, enabling seamless integration with your lab's data management systems.
• Safety & Durability: The welded steel frame features front and rear fragment guard safety doors with heavy-duty latches, shatter-resistant Lexan® inserts, and a fully enclosed test chamber. This ensures operator safety while minimizing dust and noise during operation.
• Compliance with Standards: The RF Series machines are pre-programmed to meet ASTM and AASHTO standards, ensuring precise and compliant testing. Variations in load application, discrepancies in procedures, and operator errors are eliminated for highly reliable results.
• Energy-Efficient Operation: The integrated electric motor and hydraulic pump feature advanced feedback regulation to maintain load rates with high precision. The energy-efficient design reduces noise and wear, improving overall performance and extending the life of the machine.

Testing Capabilities

The RF Series machines are capable of performing a wide range of tests, including:

• Compressive strength testing of concrete cylinders (6x12in standard, other sizes with optional accessories)
• Flexural strength testing for concrete beams
• Splitting tensile strengths of cylinders or cores
• Modulus of Elasticity (MOE) and Poisson’s Ratio determination (optional AC-300M and AC-300MR models)

Optional accessories allow for expanded testing of specimens with sulfur caps, ground ends, or alternate sizes and shapes. Specialized fixtures like compressometers and extensometers are also available for advanced testing needs.

Automation & Diagnostics

The controller automates specimen contact, preload, load rates, break detection, and piston return, ensuring highly efficient and repeatable testing. Diagnostic tools monitor system performance, including loading, safety, and communications. Fault notifications, such as piston overtravel or emergency stops, are displayed instantly, preventing test initiation until resolved.
