SV Technocrats India’s Compression Testing Machine (CTM) is a device used to test the compressive strength of materials such as concrete, bricks, and other structural components. It applies a controlled force to a sample until failure, helping engineers determine the material's strength and suitability for construction.
Components of a Compression Testing Machine
Loading Unit – The main structure that applies force to the test specimen.
Hydraulic System – Provides the required pressure for applying force.
Platen (Upper and Lower) – Steel plates that hold and compress the sample.
Load Gauge/Digital Display – Shows the applied load in real-time.
Control System – Manual or automatic controls to regulate the loading rate.
Safety Features – Protective shields and emergency stop buttons.
Types of Compression Testing Machines
Manual CTM – Uses a hand-operated pump to apply load.
Semi-Automatic CTM – Has a motorized pumping system for smoother operation.
Fully Automatic CTM – Uses digital controls for precise load application and data recording.
Testing Procedure
Sample Preparation – Specimens (e.g., concrete cubes or cylinders) are cast and cured as per standards.
Placing the Sample – The sample is positioned centrally on the lower platen.
Applying Load – The upper platen is lowered, and load is applied gradually.
Recording Results – The maximum load at failure is noted.
Applications
Concrete Testing – Ensures concrete meets strength specifications.
Brick and Block Testing – Evaluates structural durability.
Metals and Plastics – Used in material science and engineering research.
