Compression Testing Machine (CTM) – An Overview

A compression Testing Machine (CTM) is used to measure the compressive strength of a material. The CTM is designed to apply a compressive load to the sample until it fails. The machine consists of a piston that moves up and down inside a cylinder, applying the load to the sample.

The CTM machine is used in construction industries to test the quality of concrete. The compressive strength of concrete is determined by testing concrete cubes or cylinders using the CTM machine. The CTM machine can also be used to test the compressive strength of other materials such as bricks, rocks, and metals.

The CTM machine is available in different sizes, capacities, and types. The most common types of CTM machines are manually operated and digital machines. The manually operated CTM machine requires a skilled operator to control the load application, while the digital CTM machine is fully automatic and can be operated by anyone with minimal training.

The CTM machine consists of a load frame, a hydraulic system, and a data acquisition system. The load frame is the main body of the machine, and it supports the hydraulic system and the data acquisition system. The hydraulic system is used to apply the load to the sample, and the data acquisition system is used to measure and record the load and deformation data.

To perform a compression test using the CTM machine, the sample is prepared by casting it into a cube or cylinder mold. The sample is then cured for a specific period of time and tested by placing it in the CTM machine. The load is applied to the sample at a specific rate until it fails. The load and deformation data are recorded during the test, and the compressive strength of the sample is calculated using the recorded data.

In conclusion, the CTM machine is an essential tool in the construction industry to test the quality of concrete and other materials. The CTM machine can be operated manually or digitally and is available in different sizes and capacities. Proper usage of the CTM machine ensures accurate and reliable test results.

What is a Compression Testing Machine?

  • One of the most fundamental types of machine for material testing with their properties like tensile strength, elastic limits, and more.
  • Compression Tests are used to determine material behaviors under compressive pressure loads.
  • During the test, we measure different properties of materials such as elastic limits, proportional limit, yield point, yield strength, and more.

Why Perform A Compression Test?

Testing allows manufacturers to make sure about the integrity, and safety of materials, components, and manufacturing process.

Applications can vary from the strength of Glass to endurance testing of concrete beams used in construction.

Low Tensile Strength of Materials = High Compressive Strength — And Vice-versa….

Compression testing is often used on brittle materials such as concrete, metals, plastics, ceramics, composites, and corrugated materials like cardboard.

Fully Automatic Compression Testing Machine Servo Motor Controlled [FACTM]

An intelligent pace rate controller governs the operations of a servo motor controller-based compression testing machine, enabling various functionalities such as Automatic Pace Rate Control, Data Logging, Data Printing, and Load Hold. This controller manages tasks such as activating and deactivating the pump automatically, regulating the designated pace rate, and initiating machine shutdown based on predetermined conditions. At the end of each run, pressure release occurs, and the machine resets at the start of every test. The pace rate is upheld through comprehensive three-term PID feedback control using high-torque servo motors and driver sets. Complete automation encompasses data acquisition, storage, management, and analysis. Additionally, a silent hydraulic pump contributes to a more conducive work environment. Available models include: Fully Automatic Compression Testing Machine with Servo Motor Control, Cap. 3000kN, and Fully Automatic Compression Testing Machine with Servo Motor Control, Cap. 500kN.
