on earth there are variety of soils and they all exhibit different kinds of behavior properties of soils were very not only with the soil types but also with the soil green arrangement and moisture content in the soil for example we may safely assume that gravel and sand soils will behave differently and then clays but we cannot assume or say that all sands will behave alike or all clays will behave similarly a loose sand will behave differently with the same send if it is dance similarly saturated clay will behave differently from the same clay in the dry state so to understand the behavior of soil we try to evaluate its properties in terms of grain characteristics arrangement of particles and moisture content using these evaluated properties we try to classify the soil into different categories and properties of soil that help in the identification and the classification of soil are called index properties index properties can be divided into two categories soils grain properties and soil aggregate properties soil grain properties as the name suggests depend upon individual grains of soil properties in this category are mineralogical composition specific gravity of solids size and shape of grains most important properties of individual grains of soil are the particle size distribution and green shape soil aggregate properties these are dependent on soil mass as a whole and that is a huge amount of individual grains of soil put together this represents a collective behavior of soil these aggregate properties depend upon soil stress history how the soil is formed and soils the structure these properties are of greater significance for the engineering practices most important aggregate property of the soil is its a relative density we will learn all these in coming videos thank you
