Experiment on artificially-prepared clay samples by freeze-drying for SEM

CHAI Shou-xi 1,2, HAN Wen-feng1, WANG Pei2,WEI Hou-zhe n2 (1.Resources and Environment College, Lanzhou University, Lanzh ou 730000, China; 2.Department of Civil Engineering, Tianjin Institute of Urban Construction, Tianjin 300384, China)  
The principle and methods of artificially-prepa red samples by freeze-d rying for microstructure analysis are described in this paper. The samples proce ssed by freeze-drying do not shrank in volume and is no change in structure af ter dewatering, and quality of samples is well for microstructure analysis.
