Compression and Flexural Testing Machine, Automatic (E-Version)

Compression and Flexural Testing Machine, Automatic (E-Version) is a combination of compression and flexural test machines to measure the resistance to compression and bending (flexure) of cement and mortar by applying controlled forces to specimens.

The purpose of these tests is to determine which material parameters are best for construction like strength, elasticity, and deformation characteristics, which ensure the safety and durability of materials in various applications ranging from construction and manufacturing to research and development.

This machine consists of two loading frames with two independent measuring ranges for consistent performance. Its fully automatic computer control provides a constant loading rate for both compression and flexural tests. The advanced and user-friendly computer software enables results to be acquired automatically with the test curve display and result database being saved virtually unlimited inside the computer. Suitable for testing on flexural and compression of 40 x 40 x160 mm mortar prism and compression of 50 mm mortar cubes.

Test Procedure

1. Preparation of Specimens: Prepare the test specimens according to the relevant standards or specifications. This may involve casting concrete or mortar specimens in molds of specified dimensions and curing them under controlled conditions.

2. Mounting Specimens: Secure the specimens in the loading frame of the testing machine according to the test method being used. Ensure proper alignment and support to prevent any lateral movement during testing.

3. Adjustment of Testing Parameters: Set the testing parameters such as load rate, displacement rate, or strain rate depending on the specific test requirements and standards being followed. These parameters may vary based on the material being tested and the desired test conditions.

4. Initiation of Test: Start the test by applying the specified load or displacement to the specimen using the compression or flexural loading mechanism of the testing machine. Ensure that the loading is applied uniformly and steadily to avoid any sudden shocks or fluctuations.

5. Data Acquisition: Monitor and record the load and displacement or deformation data continuously throughout the test using the built-in sensors or external measurement devices connected to the testing machine. This data will be used to analyze the mechanical behavior of the specimen during testing.

6. Maintenance and Calibration: After completing the test, perform any necessary maintenance tasks on the testing machine and ensure that it is properly calibrated for accurate and reliable performance in future tests. Regular maintenance and calibration are essential to ensure the integrity of test results and the long-term reliability of the testing equipment.
