Part 1: Introduction
a. The purpose of this lab is to differentiate between two clay soil types, bentonite
and kaolinite. According to Conduto, clay soil particles are more tightly packed
together in comparison to other soil types. Being more tightly packed lessens the
soil porosity, therefore less percolation is experienced. Percolation in soils is
typically attributed to the force of gravity pulling the water vertically and
downward. The rate of percolation is primarily controlled by the size of the soil
grains (Coduto, Yeung, and Kitch 126). The soil’s specific surface therefore
allows clay interparticle forces to form. Given that these clays are different types
of clay soils, their characteristics are differ...
