Rebar quality control
Rebar testing is a destructive material testing procedure. It is carried out to ensure that the rebar meets relevant quality standards.
TMT Bars (Thermo Mechanically Treated Bars) are becoming increasingly popular around the world. There are certain tests that can be performed to help determine the quality of TMT Bar. TMT bars are available in a variety of grades, including Fe 415, Fe 500, Fe 550, and Fe 600, with the numbers indicating the yield strength.
TMT Bars must have the ideal balance of strength and flexibility. Below are the various types of tests used to determine the quality of rebar.
- Bending test: A bend test is a low-cost qualitative test used to determine the flexibility and strength of materials. Bend tests deform a test steel material in the middle, resulting in a bend without a fracture. As a result, you specify the resistance level of the material. The goal of a bend test is to load the sample material into a specific shape.
- Tension test: A material tension test is a destructive process that provides information about the sample's tensile strength, yield strength, and elasticity. This test is performed to determine how the material reacts when force is applied to it. By pulling the metal, you can usually determine the material's tensile strength, yield strength, and how much it will elongate.
- Yield strength test: Yield strength testing entails pulling a steel sample with a controlled gradual increasing force until the metal changes shape or breaks. When a metallic material exhibits the yield phenomenon, you reach a point during the test where plastic deformation occurs without an increase in force.
