400,000lbf Concrete Compression Machine, Pro-Plus Control

400,000lbf Concrete Compression Machine with Pro-Plus Control

Gilson MC-400PR: 400K Compression Machine with Pro-Plus Controller

MC-400 Series Concrete Compression Machines are accurate and reliable for testing the compressive strength of grout and mortar. The series offers many models and features to fit your testing needs. These compression testing machines have a 400,000lbf (1,780kN) capacity and come with a Fixed-Height Concrete Compression Machine Mounting Stand for safe and easy handling of samples. The machine can run full test cycles with minimal operator intervention. These rugged machines can test standard 6x12 concrete cylinders up to 11,300psi. Accessories are available to test different sized cubes, cores, masonry prisms, concrete cylinders and flexural beam concrete strength specimens, so it’s versatile for all types of samples. Frame stiffness meets or exceeds ACI 363 requirements for continuous loading. The heavy-duty construction has fully-welded corners for added stability and durability, and inside the crosshead seams, strong internal welds for added accuracy during testing. The machine performs day in and day out in demanding production environments. For those requiring higher capacity, consider the Gilson MC-500PR Concrete Compression Machine 500K Pro-Plus, which features a 500,000lbf capacity and advanced automation for enhanced testing applications.

A bottom-mounted hydraulic ram uses an upward force to compress. The first stage uses high volume and low pressure to advance the piston quickly. The 0.75 hp oil-immersed pump switches to the second stage at 135psi of pressure automatically. During this stage the low volume high-pressure flow loads at a continuous rate of 2,000–200,000lbf (8,896–889,600kN) per minute. The system can control and regulate the loading speed to get accurate and standardized results. Be sure to monitor the final load during testing to get accurate results.

The spherically-seated upper platen assembly is 6.5in (165mm) in diameter and is hardened and nickel-plated with a locking stem for quick change out of accessories. The rectangular lower platen is a compression table with a precision-ground piston with O-Ring seal and a Teflon® backup ring in a polished steel cylinder. The machine displays live data of the load being applied and allows you to easily find and select the test parameters for convenience and user-friendliness.High-pressure hydraulic safety valve and watchable steel fragment guard doors prevent overloading beyond machine capacity. Pressure bleed hole in the piston prevents ram overextension. Side-mounted controllers can be installed in an optional separate console. Choose from different controller types: automatic, manual or budget-friendly indicators to fit your application. Tests low strength concrete beams, versatile testing machine for all strength levels and can be used with a variety of testing beam molds for flexural strength specimens.

Additions or upgrades can be made to the machine: advanced controllers or software to improve functionality, automation or data management. The machine can measure the modulus of elasticity of concrete specimens and similar tools can detect and analyze rebar within concrete structures, key data on stiffness and durability.
