The instrument measures a volume loss in a specimen under abrasion
test and it’s used in tests such as:
– paving stones
– concrete slabs
– slabs made of natural rocks
– natural stone slabs
– terrazzo tiles
The test is performed by positioning a specimen to be verified in a
abrasion tester Böhme apparatus on the test track on which has
been spread normalized abrasive; the grinding wheel it’s made
rotate and the specimen submitted to the abrasive load of 294 N for
a certain number of cycles.
Before doing a test, establish the specimen’s bulk density by measuring
weight and thickness.
Perform the test for 16 cycles composed of 22 turn each, calculating
at the end a worn as a average loss in volume and weight.
The apparatus is basically composed of:
– Cast iron horizontal disc with a speed of 30 rpm and a diameter of
750mm furnished of a 200mm test track to position a specimen.
– Separate control panel with digital revolutions counter with automatic
stop after preset revolutions.
– Specimen’s holder.
– Adjustable charger used to produce a force of 294 N ± 3 N on a
Power supply: 230V 50Hz 1PH 800W
