Regarding building structures with reinforced concrete, two key elements take the spotlight: TMT Rebar and concrete. The longevity and safety of these structures depend heavily on the quality of these materials. Let’s delve into an easy-to-understand guide to ensuring their quality.
Ensuring Quality in Construction: A Simple Guide
1. Mechanical Testing for TMT Rebars:
Mechanical testing is like giving the material a health check. It serves two main purposes: providing design data and ensuring the material can handle specific stress without breaking. For example, a tensile test helps determine steel’s strength for design or to comply with standards. The supplier or a third-party testing lab usually does these tests.
2. Alternative Checks for Quality:
If you’re a civil site engineer and can’t run all the tests on-site, there are other ways to check TMT Rebars:
a. Storage & Handling:
- Estimate the needed amount of reinforcement.
- Plan storage to protect against damage from water and dust.
- Carefully handle operations like unloading, hoisting, stacking, cutting, bending, and fabrication.
b. Stacking & Storing at the Site:
- Use covered sheds and polythene sheets to protect against water and dust.
- Optimize stacking height to prevent damage to the bars’ ribs.
- Bundle and interlock properly to avoid sliding or collapsing.
- Use raised platforms and wooden blocks to keep bars off the ground.
c. Bending and Fabrication:
- Bend and re-bend carefully to prevent breakage.
- Follow specified bend diameters to avoid weakening the bars.
- Ideally, let specialists handle cutting, bending, and fabrication.
