The Dorry Abrasion Tester – Böhme is used to evaluate the abrasion resistance of aggregates, concrete slabs, natural stones, and paving units under standardized conditions.
The apparatus comprises a horizontally positioned steel disc with a 750 mm diameter, providing a defined test track for the abrasive material.
During testing, a specimen is subjected to a vertical load of 294 N while the disc rotates at 30 revolutions per minute, simulating real-world wear scenarios.
A specified quantity of standard abrasive material is distributed on the disc surface, and the specimen undergoes a set number of cycles to assess wear resistance.
The machine features an automatic digital counter that ceases operation upon reaching the predetermined number of revolutions, ensuring precise and repeatable results.
Test outcomes are determined by measuring the volume loss of the specimen, providing critical data for quality control and material performance assessment.
