Characterization of Eggshell and Natural Chloride Stabilized Soil Using Geophysical Techniques

What is it about?

In the present study, correlations between geophysical and compaction tests results have been derived. Eggshell powder (ESP), a waste material along with sodium chloride (NaCl) and polypropylene fiber (PPF) was used to stabilize the soil. Design of experiments was done by Taguchi technique using Minitab 17 software. A series of non-destructive geophysical tests i.e., Ultrasonic pulse velocity (UPV) and Electrical resistivity (Re) tests was carried out on 21 days aged soil specimens.

Why is it important?

Although many techniques are available for the evaluation of soil parameters, but a quick and efficient method is always welcome. To avoid the hassle calculation and tedious procedures of testing; practitioners seek a fast method for site implementation of laboratory results. In the recent era of development and technology, it has been necessary to adopt the advanced techniques to evaluate the geotechnical parameters.
