Abrasion Resistance of Concrete

Abrasion Resistance of Concrete

Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.
One such test is the revolving disc test, where three plates...

Summary

This study introduces a new method using an improved synthesized health index (ISHI) and time adaptive threshold (time-ATH) to accurately detect wheel defects using acoustic emission (AE) technology, even with significant wheel-rail rolling interference (WRRI). The proposed approach enhances detection accuracy and rate for flattened wheel defects.
