Description The West Cerchar Abrasivity Index Tester is designed to determine the rock abrasivity index (CAI) for the purpose of quantifying the classification of rock materials abrasivity. This type of test is especially valuable in the mining industries, underground construction […]
This universal saw, completed with the suitable accessories, can be used to cut concrete and rock cores, and irregular rock samples in order to obtain geometrically defined samples. It can be fit with 300 to 450 mm dia. blades.
This apparatus was originally developed at Imperial College, London, by Professor E. Hoek. It is a simple and practical method of determining the strength and slope stability of rock, both in the field and in the laboratory.
The apparatus consists of a load frame 60 kN cap. with a hydraulic loading ram actuated by a hand pump. The frame is adjustable for testing samples up to 102 mm dia.
NG-CoreTrim is used to obtain rock samples perfectly machined (cube, prisms, etc) from irregular rock or core pieces. It is supplied complete with a proper vice to hold irregular pieces firmly in place up to 7x14
This machine is specifically used in the laboratory for cutting core samples from hard materials such as rock and concrete.
