Soil Investigation - Weebly

The sedimentation test is an easy way to measure the percent sand, silt, and clay in a soil sample. It is based on the fact that large heavy particles will settle most rapidly in water, while small light particles will settle most slowly. The Calgon laundry powder is used to dissolve the soil aggregates and keep the individual particles separated
