2.2.5. Abrasive Wear Tests

Wear tests were conducted to determine the abrasion resistance of the material. Following the recommendations of the NBR 12042 standard [42], 70 mm × 70 mm × 30 mm samples were compressed with a constant and standard force against a circular-shaped track covered with sand, which ran at a specific speed. After a 500 and a 1000 m run the dimension difference was observed on the original 70 mm × 70 mm × 30 mm samples and the resistance was determined by the amount of material lost per distance.
