"WebJan 15, 2024 · Introduction. Soil particle density (Dp) is an important soil property used in calculation of porosity and void ratio. Typically Dp is not measured but assumed a constant (e.g., Dp = 2.65 Mg m − 3).Void ratio is often used in soil mechanics (e.g., Keller et al., 2011), and reliable estimates are important in the interpretation of soil mechanical behavior.
