Soils are aggregates of mineral particles; and together with air and/or waterin the void spaces, they form three-phase systems. A large portion of the earth’s surface is covered by soils, and they are widely used as construction and foundation materials. Soil mechanics is the branch of engineering that deals with the engineering properties of soils and their behavior under stress. This book is divided into 11 chapters: “Soil Aggregate, Plasticity, and Classification,” “Stresses and Strains: Elastic Equilibrium,” “Stresses and Displacement in a Soil Mass: Two-Dimensional Problems,” “Stresses and Displacement in a Soil Mass: Three-Dimensional Problems,” “Pore Water Pressure due to Undrained Loading,” “Permeability,” “Seepage,” “Consolidation,” “Shear Strength of Soil,” “Elastic Settlement of Shallow Foundations,” and “Consolidation Settlement of Shallow Foundations.” This chapter is a brief overview of some soil properties and their classification. It is assumed that the reader has been previously exposed to a basic soil mechanics course.
SOIL: SEPARATE SIZE LIMITS
A naturally occurring soil sample may have particles of various sizes. Over the years, various agencies have tried to develop the size limits of gravel, sand, silt, and clay. Some of these size limits are shown in Table 1.1. Referring to Table 1.1, it is important to note that some agencies classify clay as particles smaller than 0.005 mm in size, and others classify it as particles smaller than 0.002 mm in size. However, it needs to be realized that particles defined as clay on the basis of their size are not necessarily clay minerals. Clay particles possess the tendency to develop plasticity when mixed with water; these are clay minerals. Kaolinite, illite, montmorillonite, vermiculite, and chlorite are examples of some clay minerals.
