The main electrical resistivity properties of the cement soil are given by laboratory and field tests. Research shows that the cement soil with higher unconfined compression strength

higher cement content

longer time and lower water content

has higher electrical resistivity. In addition

The orthogonality test results indicate that factors influencing on the electrical resistivity of the cement soil are salt content

cement content

water content

flyash content

lime content in succession. By comparing field electrical resistivity test with standard penetration test

pile boiling observatin

it can be concluded that the electrical resistivity test is available for checking engineering quality of the cement deep mixing pile.
