RESEARCH ON THE MICROSTRUCTURE AND THE MECHANICAL PROPERTIES OF SHENGZHOU DIATOMITE

Diatomite, as one of the special clay soils, the determination of microstructure, the physical and mechanical properties are the keys to develop engineering surveys and design of diatomite foundation. Various testing measures were used to study the microstructure, physical and mechanical characteristics of Shengzhou diatomite samples comprehensively. The results indicate that diatomite samples have multiple pore microstructure, high compressibility and strong structural. Meanwhile, macroscopic physical and mechanical properties are closely related to the multiple pores and strong structure of diatomite. The conclusions can be used for the reference in the engineering investigation and engineering experimentation in diatomite areas.
