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

1. Loading Unit – The main structure that applies force to the test specimen.

2. Hydraulic System – Provides the required pressure for applying force.

3. Platen (Upper and Lower) – Steel plates that hold and compress the sample.

4. Load Gauge/Digital Display – Shows the applied load in real-time.

5. Control System – Manual or automatic controls to regulate the loading rate.

6. Safety Features – Protective shields and emergency stop buttons.

Types of Compression Testing Machines

1. Manual CTM – Uses a hand-operated pump to apply load.

2. Semi-Automatic CTM – Has a motorized pumping system for smoother operation.

3. Fully Automatic CTM – Uses digital controls for precise load application and data recording.

Testing Procedure

1. Sample Preparation – Specimens (e.g., concrete cubes or cylinders) are cast and cured as per standards.

2. Placing the Sample – The sample is positioned centrally on the lower platen.

3. Applying Load – The upper platen is lowered, and load is applied gradually.

4. 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.
