Paper Title:
Study on the Electrical Model of Cemented Soil
  Abstract

Cemented soil resistivity is one of its inherent properties which can be used to detect its unconfined compressive strength and polluted state. But the cemented soil resistivity is macroscopic showing of its microstructure conductivity. Its resistivity closely relates with resistivity of various material components, such as soil porosity, cement mixing ratio,etc. So further researching the electrical model of cemented soil is great significance. This paper introduces the existing cemented soil electrical model(Komine model). Then based on the microstructural observation of the SEM images of cemented soil, the problems of Komine model are pointed out. Furthermore a more reasonable microstructure is proposed. The new electrical model of cemented soil is set up on three hypotheses. This new model is composed of parallel structure and series structure. Some soil particles surrounded by the hydration products such as CSH or CASH connect with pore water parallel to form the series structure. The hydration products that continue to harden to form the cemented soil skeleton connect with soil particles and pore water to form the parallel structure. The new electrical model of cemented soil can explain better electrical conductive mechanism of cemented soil materials.
