IV. Testing Applications

The TD558-1 Concrete Flexural Strength Test Fixture is suitable for testing the flexural performance of cement concrete specimens. It can be used to determine concrete flexural strength and related flexural deformation properties under specified loading conditions.

Typical applications include:

Concrete flexural strength testing;

Concrete beam bending tests;

Flexural-tensile strength testing of cement concrete;

Concrete flexural modulus of elasticity testing;

Quality control of concrete materials;

Laboratory research and development;

Evaluation of concrete used in roads, bridges, pavements, and other construction projects.

V. Suitable for Concrete Beam Specimens

The TD558-1 is designed for prismatic concrete specimens and can be installed on a suitable testing machine according to the required test configuration. Its beam-type loading arrangement makes it suitable for laboratory testing of concrete specimens subjected to flexural loading.

VI. Testing Principle

During the test, the concrete prism specimen is placed on the supporting points of the fixture. Load is applied through the loading points at the specified positions until the specimen reaches flexural failure. The maximum applied load is used to determine the flexural strength of concrete according to the applicable test method.

For modulus of elasticity testing, the corresponding deformation of the specimen is measured during loading to evaluate its flexural modulus of elasticity.
