Mangaluru: DST SERB (Science and Engineering Research Board) sponsored a Two Day Workshop on NDT Techniques & Repair Material Characterization NRMC-22 at NITK on Nov 3,4.
This workshop addresses both the macro and micro-level characterization of repair materials as well as features of non-destructive testing. The quality, strength, and current condition of a structure, such as a dam, a bridge, etc., can be evaluated using either destructive testing methods or non-destructive testing. Destructive methods distraught the structure’s materials and which is inappropriate for the majority of structures because it results in structural damage. On the other hand, non-destructive testing procedures use equipment like rebound hammers, acoustic emission techniques, etc. to assess the current condition of the structures without causing any damage to them.
The Need for NDT:
Concrete buildings are complicated; thus, we need multiple tests to assess their state which is included in the first part of the workshop. Repair material Characterisation is the workshop’s second part. After assessing the structure, we restore or rehab it. In this section, we will review the materials utilised in the industry today for this purpose.
Dr Palanisamy: If we need to repair a 40-year-old RCC structure, using modern concrete alone won’t be effective because it won’t be compatible with the material that was used at the time. Instead, we will need to have a thorough understanding of the repair materials in order to complete the assessment and repair”.
One course on the same topic is being offered by the Department of Civil Engineering NITK at the B.Tech level entitled “Non-Destructive Testing and evaluation of concrete structures”.
Utility of the course: Knowledge of the course would help to evaluate the present condition/health of the structures and future increase the life of the structure, which has a very high demand in the market today.
Course stats: 47 students enrolled from B.Tech final year.
The B.Tech level “Non-Destructive Testing and Assessment of Concrete Structures” course is being offered by the department of civil engineering at NITK on the same subject.
Understanding the course will help analyse the structures’ health and condition to prolong their lives, which is in high demand. Currently, 47 B.Tech final-year students are enrolled.
