Concrete Component Compressive Strength Testing Machine

Product Overview

The concrete component compressive strength testing machine is mainly used for compressive testing and research of concrete, cement mortar, rock, pipe piles and other building components. It can also test various metals, non-metals and composite components. The precise automatic control and data acquisition system realizes full digital adjustment of data collection and control processes. It supports multiple control modes including automatic load holding, stress control, strain control, cyclic loading and unloading and self-programming control. Tests can be performed and test data provided in accordance with national GB standards as well as ISO, JIS, ASTM, DIN and BS international standards, automatically detecting bearing capacity, strength and other test parameters of materials.

Product Features

1. Four-column lead screw structure with top-mounted hydraulic cylinder, large test space, high rigidity and excellent stability.
2. Servo measurement and control system to realize automatic loading at constant rate, constant test force holding and cyclic loading & unloading.
3. Automatic, manual and fixed load operation modes available.
4. Dual-control bidirectional hydraulic cylinder for fast testing and rapid return.
5. Equipped with safety protection devices.

Measurement & Control System

Automatic control, data collection, processing, analysis, storage and display of test processes. Intelligently set control modes with smooth switching without impact between control modes, stable loading and unloading. Process replay and re-analysis of data; curves support zooming, comparison and traversal; curves can be freely scaled with full-scale self-calibration. Modular open programming control software with customizable personalized design, including standard modules, permission management module, test module, control module, analysis module, query module and output module, with operation prompts and wizards. Adopts ACCESS format database preloaded with multiple test methods and standards. Circuit boards adopt photoelectric isolation design for strong anti-interference performance. Flexible Excel or Word report formats with optional sorting, separate or combined printing. Supports network database management.

Multiple Protection Functions

Cylinder limit protection; hydraulic system overload overflow protection; test force overload protection; overcurrent and overvoltage protection; safety protection upon specimen fracture; operation prompt guide protection; automatic protection after test completion.
