This section includes a range of products to investigate abrasion and durability on natural stone and rocks, in common with also other material such as concrete and aggregates. In particular for determining the resistance to the abrasion, the Abrasion testing machine and Bohme Abrasion Wheel machine and for assessing the deterioration of material subjected to water immersion the Slake Durability Apparatus
Used for determining the resistance to abrasion/wear of natural stones.
Standards EN 1338 EN 1339 EN 1340 EN 14157 EN 1341 EN 1342 EN 12808-2 EN 14617-4
This machine has been developed for determining the resistance to abrasion/wear of natural stones and concrete products. Easy to use, electronic control of the disc speed with auto shut-off of the machine at the selected number of revolutions. The abrasion disk wheel is 70 mm thick. Supplied complete with 5 kg of white corundum FEPA grit size 80 and calibration sample (Boulonnais marble).
The machine can also be converted, by the conversion kit 48-D0471/K, for abrasion test conforming to EN 1344, 10545-6, 14617-4, 12808-2, UNE 127024.
See accessories.
The standard version conforms to EN 1338, 1339, 1342, 14157, 1340, 1341.
Abrasion testing machine. 110 V, 60 Hz, 1 ph
Used for testing of: natural stones, concrete paving blocks, flags, kerbs, screed materials...
Standards EN 1338 EN 1339 EN 1340 EN 14157 EN 13892-3 EN 13748 DIN 52108
The disc abrader conforming to Böhme method consists of a rotating wheel made of cast iron, 750 mm dia., with a defined test track to receive the abrasive material (white corundum sand) and a no-vibration specimen holder with a two arms lever loading device.
The test speciment is clamped with an holder and submitted to a test force of 294 +/-3 N. After the abrasive is strew on the disc, the disc starts to rotate with a constant speed for a certain number of cycles (according to Standards).
At the end of the test the abrasion effect is measured as the loss in specimen thickness or volume.
This machine is used for testing of:
(Testing specimens in wet or water-saturated conditions is not feasible).
The machine is equipped with a display control panel that allows the setting of speed and number of cycles. Once the machine is started, it will automatically stop at the end of the set number of cycles programmed on the controls panel.
White carborundum abrasive sand and measuring device of sample thickness reduction have to be ordered separately.
The measuring device, basically a 0.01mm resolution dial gauge mounted on a reference base, allows to measure the sample thickness in 9 points as defined as alternative abrasion measurement method in EN 13892-3 and DIN 52108. Volumetric method is valid for all the standards.
