Dear Members of Mailbase I did the UCS test using cement-treated Kaolin. For the sample preparation I used humidity room with 96% relative humidity.The humidity room temperature was 22 degree. The sample condition was 2, 5 and 10% cement ratio with 70% water contents. Before I did the tests I checked the volume change and shrinkage of samples. The volume change of 2% cement ratio was lager than the 5 and 10% cement ratio. Even though I observed cracks on the surface of 2% cement ratio. I wonder why small cement ratio makes a larger shrinkage than high cement ratio. Would you please let me know it if you have any information on them.
