However there may be a couple of factors that may render the final results incorrect to a certain extent. Firstly, no correction or allowance was offered on the behalf of the strength of the rubber membrane used to confine the soil samples. The strength of membrane would have been higher than the shear strength of the soil and it should have been adjusted in the results accordingly. Secondly, the experiment was not repeated for each sample at their cell pressures thus there was no service for checking for consistency of the results observed and knowing if there were any errors.
