Hi.. I'm looking for any sugestion on how to core soft rock (eg. shale)in laboratory.

RE: weak rock
Well....a few questions come to mind
What size and length of core are you trying to get?
What is the size of the block of shale?
How hard/soft is the shale?
How quickly does the shale react to water, i.e. does it soften quickly?
Oh yea, lastly WHY?
If you give me answers to some of the above, I might have some ideas. I have done odder things in the past, though maybe not much odder.

Semantics aside, do you call it Soft in the states?? British Standards calls it weak.

RE: weak rock
We all should be more careful with the terms that we use. For geotechnical engineers, most of the product that we produce is written. If we are sloppy and/or inconsistent in what we write, then it not only reflects badly on the individual doing the writing but on the profession as whole.

The diameter of the core is 55 mm. The sample is prepared for uniaxial compressive strength test. Instead of using water during a coring process, is there any method or liquid / foam which more preferable?.
The hardness of the sample could be considered as "soft" rock
RE: weak rock
Incidentally,,, the hardness of a mineral sample could be soft, but the strength of a rock should be very weak to very strong. ( I thought that we'd covered this already?)
RE: weak rock
Otherwise I agree with soiledup.
