Thanks for impactful video. I will love you to help with video lectures on the following sir.
1. How to determine OCR from one dimensional consolidation test.
2. How to carry out constant and falling head permeability test on site/field.
Best regards

please i would like to know if C'c is the same as Cr which is also Cs , compression index at post-yield stage ? can you show me how to find C'c please. I still cant get how to do that. Thanks

Thanks for watching dear

[@MasterCivilEngineering]

Cr is the recompression index and Cc is the compression index. They are two different quantities

[@MasterCivilEngineering]

We also sometimes write Recompression index as Cs so Cr and Cs both are used to denote recompression index

@@MasterCivilEngineering okay. but please how do i calculate the compression index at post-yield stage C'c ? i did some experiments on consolidation and i would need themfor my thesis , i just dont know how to go about this. thanks for replying my message 🙏🙏🙏
