Overview
The GuanCe Instruments GCTKY-100KN Universal Flexural and Compressive Testing Machine is a dual-function electromechanical testing system engineered for precision mechanical property evaluation of rigid and quasi-brittle materials. It operates on a closed-loop servo-controlled loading principle: a high-performance AC servo motor drives a precision ground ball screw to apply controlled axial force to the specimen, enabling accurate implementation of ISO 6892-1, ASTM E4, ASTM C78, ASTM C39, and GB/T 3074.1–2021 test protocols. Unlike hydraulic systems, this machine eliminates oil leakage, thermal drift, and maintenance-intensive pump operation—delivering stable, repeatable load application across extended duty cycles (7×24 h continuous operation). Its lower-beam (sub-frame) structural configuration ensures low center-of-gravity stability, rapid specimen alignment, and unobstructed access during flexural three-point or four-point bending setup.
Key Features
- 100 kN maximum rated capacity with dual-mode capability: compressive testing (e.g., concrete cubes, ceramic tiles) and flexural strength testing (e.g., mortar beams, refractory bars) using interchangeable fixtures.
- AC servo-driven actuation system with zero heat accumulation—enabling uninterrupted long-duration tests without thermal derating or cooling downtime.
- High-rigidity all-steel monolithic frame construction with optimized stress distribution; fatigue-rated for ≥500,000 cycles at 80% full scale.
- Multi-mode closed-loop control: constant-rate loading (kN/s), constant-rate displacement (mm/min), and constant-rate strain (mm/mm/min), programmable via embedded controller or PC interface.
- Integrated safety architecture including overload cut-off (110% FS), specimen fracture detection (load drop threshold), piston stroke limit switches, and emergency stop circuitry compliant with IEC 60204-1.
Sample Compatibility & Compliance
The GCTKY-100KN accommodates standardized specimens per national and international standards: prismatic cement mortar beams (40 mm × 40 mm × 160 mm, GB/T 3074.1–2021), concrete cylinders (Φ150 mm × 300 mm, GB/T 50081), fired clay bricks (240 mm × 115 mm × 53 mm, GB/T 2542), and ceramic tiles (100 mm × 100 mm, GB/T 3810.4). It supports both third-point and center-point flexural configurations with adjustable support span (100–300 mm). All force transducers are calibrated traceable to CNAS-accredited laboratories and certified to ISO/IEC 17025 requirements. The system meets mechanical safety provisions of GB/T 2611 and electromagnetic compatibility per GB/T 18211.
Software & Data Management
The system integrates with GuanCe’s GC-TestSuite v3.2 software (Windows 10/11 compatible), providing full GLP-compliant data handling: user-level access control, electronic signatures, audit trail logging (per FDA 21 CFR Part 11 requirements), automatic report generation (PDF/Excel), and raw data export in CSV format. Real-time curve plotting includes load–displacement, stress–strain, and flexural stress–deflection profiles. Calibration parameters are digitally locked and password-protected; firmware updates preserve historical calibration records. Optional network deployment enables centralized lab management across multi-station environments.
Applications
- Construction Materials Quality Assurance: Routine compression testing of concrete cores, mortar cubes, and autoclaved aerated concrete (AAC) blocks; flexural evaluation of precast beams and fiber-reinforced cementitious composites.
- Infrastructure Inspection: Field-lab verification of pavement slabs, railway sleepers, and bridge deck components under EN 12390-3 and JTG E30-2005 protocols.
- Academic Research: Mechanical characterization of geopolymer binders, recycled aggregate concretes, and bio-based composites—supporting modulus of rupture (MOR), modulus of elasticity (MOE), and fracture energy derivation.
- Industrial R&D: Process optimization for refractory linings, stoneware glazes, and polymer-modified tile adhesives through controlled loading ramp analysis and failure mode documentation.
FAQ
What standards does the GCTKY-100KN comply with for flexural testing?
It fully implements GB/T 3074.1–2021, ASTM C78, ISO 679, and EN 196-1 for flexural strength determination.
Can the machine perform split tensile (Brazilian) testing?
Yes—when equipped with the optional diametral compression fixture (ASTM C496), it delivers traceable tensile strength values for cylindrical concrete or rock specimens.
Is third-party calibration certification included?
A factory calibration certificate traceable to NIM (National Institute of Metrology, China) is provided; CNAS-accredited field calibration services are available upon request.
What is the typical force measurement uncertainty?
At 10–100% of full scale, the system achieves ≤±0.8% indication error per ISO 7500-1 Class 1, verified annually per internal SOP.
Does the software support LIMS integration?
Yes—via ASTM E1384-compliant HL7 and ODBC interfaces for seamless bidirectional data exchange with laboratory information management systems.
