This module introduces the rebound hammer, its history, and its importance in modern construction. Learners will understand its role in non-destructive testing (NDT) and how it is used to assess concrete strength and uniformity on-site.
This module explains the components and working mechanism of the Schmidt hammer. Participants will learn the different types of hammers (N-type and L-type) and how to select the right one for specific testing conditions.
This module focuses on proper preparation before testing. It covers surface preparation, selection of test locations, and how to calibrate and set up the hammer to ensure accurate and reliable results.
This module explains the standard procedure for conducting rebound hammer tests. Participants will learn the correct testing steps, proper impact techniques, and key considerations to ensure accurate and consistent results.
A guided session where the instructor demonstrates each component of the Schmidt hammer, explaining its function, operation, and proper handling for accurate testing.
This on-site session demonstrates how to carry out rebound hammer testing on real concrete surfaces. Participants will observe the full testing process, including positioning, impact execution, and real-time data collection under field conditions.
This module covers common issues encountered during rebound hammer testing and how to resolve them. It also teaches proper maintenance, handling, and storage practices to ensure accuracy, reliability, and long-term performance of the device.
This module explores advanced uses of the rebound hammer and how to interpret results with greater accuracy. Participants will learn data analysis techniques, result correlation, and how to apply findings in real structural assessments and decision-making.
