Porosity and tortuosity influence on geophysical properties of an artificially cemented sand

摘要

Electrical resistivity, saturated hydraulic permeability and P wave velocity are investigated for an artificially cemented sand. The calibration of some known equations used in geophysical characterization tests relating these properties is done considering the presence of artificial bonds. In this case bonds are the hydrated cemented minerals coating the grains. An extensive set of experimental tests was performed, which data is presented in the paper. Artificially cemented sands were prepared with different cement dosages and different water/cement ratios in weight for each dosage. Bonds distribution in the tests performed was controlled by the water used in grout preparation.
