2The nature of SoilSoil is defined as a collection of mineral particles that was formed due to the weathering process of igneous rock and mixed with organic matter.The void between particles is filled with water and gas.Cementation among the particles is weak and is due to carbonation and oxidation between particles and or organic matter.Characteristics of soil in general are greatly influenced by the process of the soil formation.The structural arrangement of the particle may be loose, medium dense or dense depending on the packing of material.
18Example: Volumetric Ratios Determine void ratio, porosity and degree of saturation of a soil core sampleData:Weight of soil sample = 1013gVol. of soil sample = 585.0cm3Specific Gravity, Gs = 2.65Dry weight of soil = 904.0g
