Basic consolidation test of samples of disk geometry constructed without using bonding materials. (a) Comparison between resultant samples with different particle sizes and the same weight fraction. Samples D1–D10. One hundred and twenty hours after removing samples from compression molding. (b) Comparison between resultant samples with same particle sizes and different weight fraction. Samples D4, D14 and D24. One hundred and twenty hours after removing samples from compression molding.
