Abstract:
Specimens of Georgia kaolinite were compacted on 4-in. molds at three compaction efforts having 7,425, 42,750, and 78,750 ft-lbcu ft of energy, respectively. Samples representing each effort were compacted at water contents which were 5 and 1 percent dry and 1 and 5 percent wet of optimum water content. After compaction, these samples were studied in the scanning electron microscope, which revealed that the compaction had produced some degree of dispersed or face-to-face orientation of the clay platelets. The dispersed orientation was not particularly enhanced at the higher compaction efforts. Also, there was no evidence of any enhancement of this orientation on the wet side of optimum for those samples compacted at 42,750 and 78,750 ft-lbcu ft.
