consolidation Test

[CM1326]

Hi

I would like to get some advise in consolidation test for kaolinite and bentonite.
I am doing the experiment and I got initial void ratio for kaolinite is 1.343 and for Bentonite is 1.542.
Is these number correct?

Both of these materials can swell when saturated, so your void ratio could exceed 1. You have not given enough information for us to know if your values are correct. They are higher than I would expect.

Bentonite is used a a borehole sealant for its swelling characteristics and has a plasticity index of greater than 100 and would be what I define as super plastic as high plastic just doesn't fully capture the properties.

Thanks everyone for your time to take a look on my question.

In addition to the previous posting, I have populated some of the data below from my consolidation test to complete the calculation of the initial void ratio.

As an example I am taking the Kaolinite data, as follows.

- Inside diameter of the ring, ID = 6cm
- Height of specimen, Hi = 2cm
- Mass of dry specimen, Ms = 64gr
- Specific of solids, Gs = 2.7
- Density of water , Pw = 1gr/cm3
- Height of solids, Hs --> was calculated of 0.854cm

The calculated initial void ratio for Kaolinite would be 1.341.


For further calculation details, I have attached my calculation procedure to determine initial void ratio;
