Triaxial test
Triaxial test
(OP)
Hi,
I want to know which type of triaxial is able to withstand the highest strain in a specimen. The specimen is a mix of water, cement and bentonite.
The spec states Strain greater than 6% without cracking, obtained in a triaxial cell at 28 days under a confining pressure of 100 kPa at a strain rate of 0.1 % per minute.
Thanks in advance,

Why not just an unconfined compression test with strain measurements?

Thank you all for your posts.
I didn't specify the expected strength of the material. The material has very small cement content and the final strength is close to 250 kPa at 28 days.
The specifications request a triaxial test, but it doesn't mention the type of triaxial to be used. The requirement is to achieve 6% strain without cracking while testing in a triaxial. I find this difficult to probe.
How can I probe that the specimen didn't "crack" at 6%?
By visual method?
By Graph of stress vs strain?
By completing a k-test after failure?
What is your opinion?

Just check the capacity of the load cell. A 5kN load cell is good for up to 2500kPa axial stress.
