![]() ![]() The two most common involve a specific gravity bench or a specific gravity flask, also known as a volumetric or Le Chatelier flask.Ī specific gravity bench allows you to weigh suspended samples in water. ![]() ![]() There are a couple of ways you can perform this test. How Do You Perform A Specific Gravity Of Soils Test? Engineers use these measurements to perform important calculations that predict whether the soil at a site will be stable enough to support a structure and allow proper drainage. It also indicates how saturated the soil is with water. Knowing the specific gravity of soils helps engineers understand how porous the soil is or how many voids it contains. In general, the specific gravity tends to fall between 2.65 and 2.80, with coarser soils generally having lower specific gravities than finer soils. As such, the specific gravity of soil solids is actually an average of the specific gravity of all included soil particles. The name "specific" is a bit misleading since soil solids are made of so many different particles, each with their own separate gravity measurements. The "specific gravity" of soils and soil solids refers to the mass of solids in the soil compared to the mass of water at the same volume. #SPECIFIC GRAVITY LAB PURPOSE HOW TO#Learn more about this informative test, how to perform it and what makes it so crucial to your project's success. Testing the specific gravity of soils is one of the most important. There are many different ways that engineers can learn about the properties of soil at a construction site. ![]()
