HELP! Drained Test Results Looks Like Undrained Test

[shtlock]

Hi! So I stabilized a clay soil (CH) with the use of a geopolymer (quarry dust-based) and subjected it with wetting - drying cycles and CD Tests, however, the CD Test results gives around 1200 kPa for deviator stress no matter the confining pressure used (I used 100, 200, and 300 kPa). Now when I plot the Mohr-Coulomb Failure Criterion, it results to a very high cohesion yet very low angle of int. friction. Any help to maybe justify the results or is something wrong? Thanks!

post your plots. you have made yourself a weakly cemented rock

Here are the plots, please tell me if it cannot be viewed. The mohr coloumb line is about 5 to 6 degrees and cohesion is around 580 kPa. Thanks for your input!
