The AAV Abrasion Machine provides a measure of the resistanceof aggregate to surface wear by abrasion, it consists of a flat circular cast iron grinding lap 600 mm dia which rotates in a horizontal plane at a speed of 28/30 r.p.m.<br>
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. Complete with ...
Abrasion Testing Machine is designed to determine the resistance to abrasion and wear of natural stones and concrete products. The abrasion wheel is 70 mm thick and rotates with speed of 75 r.p.m. The machine is equipped with digital counter which stops the ...
The Accelerated Polishing Machine is used to measure the resistance of road stone to the polishing action of vehicle tires on a road surface.
The Polished Stone Value (PSV) of a material used as road surfacing is a measure of how rapidly it becomes polished under the action of vehicle tires. This machine is used to produce accelerate polishing, conforming to Standards, of stone chippings set onto ...
Aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Ten Percent Fines Value used for testing aggregate smaller than 10 mm.
