Comparison Between Destructive and Nondestructive Tests in the Evaluation of Abrasion Resistance of Concrete

摘要

Constant loading and transportation of materials cause abrasive wear in industrial floors.This study compared destructive and nondestructive testing techniques to evaluate the abrasion resistance of concrete. Eight concrete hardeners (six solid and two liquid) were subjected to abrasion, ultrasound, and rebound hammer tests. The results of the trials were compared to identify the concrete hardeners that provide more abrasion strength, and also to determine the relationships between the tests. The results indicated that solid hardeners provide more abrasion resistance than liquid ones and that the abrasion, as a destructive test, and the rebound hammer, as a nondestructive test, show similar results.
