Concrete Compression Machine

A compression test determines behavior of materials under crushing loads. The specimen is compressed and deformation at various loads which is then recorded. There are two types of frame available; a 4- Columns type or a Wall type.

• The equipment is suitable for testing 150 x 150 x 150 , 200 x 200 x 200 mm cube and 150 x 300 mm cylinder concrete samples.
• The 4-Column frame has a rigid load. The columns are screwed free from play to the machine’s foot and head.
• The machine’s foot and head are cut from solid, all bearing surfaces and are mechanically machined.
• A compact frame, formed by upper and lower platens. Platens are machined on all sides, hardened on both sides and face grinded.
• The upper platen is spherically seated to allow an inclination up to 3° for homogenous loading.
• The lower platen is marked to allow centring of both cubes and cylinders.
• The test cylinder has single acting feature, cut from the solid
• Distance plates are available for different size samples (10mm, 20mm, 50mm, 80mm).
• The piston is hardened and micro finished and stroke limitation by end-switches.
• The piston is protected against dirt and made of sheet steel.
• The security door is fixed at rear of the frame and is openable and closable at the front. Depending on electrical safety switch, the test machine just works fine if the door is closed.

Digital Readout Unit

LCD graphics data acquisition and controls system PCM304 is designed to control the machine and processing data from load cells or pressure transducers installed on the compression machine frame. Easy to read LCD graphics display and touch-button data pad keys make the unit quick and straight forward to operate.

All interactions with the measuring system are via the front control panel by using simple menu-driven procedures. The PCM304 is contained in light alloy housing and it’s design satisfies the ergonomic requirements for various use. The PCM304 digital allows real time load us time graph.

At the end of the test cycle, the results can be stored in the large memory or downloaded to a PC in PCM304 software format. Dedicated software package is available for further online data processing data base management and certificate printing.
