Concrete Compressive Strength Testing Machine

Automatic Concrete Compression Testing Machine

This servo hydraulic concrete compression tester complies fully with GB/T50081, EN 12390-3 and ASTM C39 global test standards, serving multi-scenario strength detection demands. It performs compressive strength tests on standard 100/150/200mm concrete cube specimens, Φ100/Φ150 concrete cylindrical samples, cement mortar blocks, clay bricks, aerated blocks, rock core samples and natural stone. Widely equipped in third-party CMA testing laboratories, ready-mixed concrete batching plants, construction engineering quality inspection stations, university civil engineering labs, road & bridge infrastructure projects, and precast component factories across global markets including Southeast Asia, Middle East, Europe and Africa. Optional auxiliary jigs support splitting tensile test and elastic modulus measurement to expand testing functions.

The whole machine adopts integrated thickened steel plate welded four-column frame, paired with high-hardness chrome-plated solid support columns. The thick cast iron base eliminates overall deformation even under full 2000kN/3000kN load, maintaining long-term structural stability. Standard built-in fully transparent explosion-proof safety shield with lockable door design, which can completely block broken concrete fragments to prevent operator injury during specimen crushing. The upper loading handwheel uses precision trapezoidal screw for smooth manual height adjustment of the upper platen. The test platens are made of high-strength quenched alloy steel, with anti-wear and anti-pressure features, and matched with a spherical self-leveling bearing seat to automatically offset specimen placement deviation and avoid eccentric force damage to the machine and test errors. The control cabinet shell is cold-rolled steel with anti-rust electrostatic spraying, dustproof, waterproof and corrosion-resistant for long-term lab use.

Equipped with high-precision pressure sensor and closed-loop servo hydraulic control system, the force measurement accuracy reaches Class 1 with indication error ≤±1% full scale, meeting strict metrology calibration requirements for official inspection institutions. Supports adjustable constant loading speed from 0.02MPa/s to 1.0MPa/s, strictly matching the standard loading rate requirement for normal and high-strength concrete. The touch screen synchronously displays real-time force value, stress, loading curve and test duration. The system automatically locks the peak breaking force the moment the specimen cracks, no manual recording needed. Massive built-in storage space stores thousands of groups of original test data; users can export complete test reports with curves via USB drive, directly print formal laboratory documents for project filing and third-party audit. Consistent repeatability of test data effectively eliminates manual operation errors compared with old manual hydraulic testers. Multiple safety protection mechanisms including overload stop, over-travel protection and hydraulic pressure alarm avoid invalid tests caused by abnormal operation.

All testing workflows are visualized on the 10-inch industrial touch screen with intuitive graphic operation interface, no complex professional training required for operators. One-click automatic test cycle: automatic loading, peak capture, automatic unloading after specimen fracture, greatly reducing manual intervention. Integrated hydraulic power unit with silent servo motor generates low running noise, built-in heat dissipation holes to stabilize oil temperature during long-time continuous testing. The cabinet drawer is reserved for storing tools, test reports and auxiliary fixtures, making the laboratory layout neat and tidy. The hydraulic oil circuit adopts high-quality sealing parts to reduce oil leakage risk; all wearing parts are standardized universal accessories for convenient global replacement. Regular maintenance only requires simple oil level inspection and platen residue cleaning, cutting long-term equipment operation costs for clients. CE certification is available to clear customs smoothly for overseas orders, and we provide complete English operation manuals and remote video installation guidance.
