Basic Definitions and Simple Tests on Soil Mechanics Introduction This page discuss some of the basic definitions and simple tests used throughout the subject. The phase diagram is a simple, diagrammatic representation of a real soil. The phase diagram is also known as block diagram. A soil mass consists of solid particles, water and air, which are segregated and placed separately, known as three-phase system. A three-phase system becomes a two-phase system when the soil is absolutely dry (solids + air) or when the soil is fully saturated (solids + water). In phase diagram, volumes are represented on the left side, whereas weights are represented on the right side. Volumetric Relationships In total, there are fi ve volumetric relationships. These are as follows: 1. Void ratio (e): It is defi ned as the ratio of volume of voids to volume of solids. Range: e > 0 e = Vv/Vs For some soils, it may have a value even greater than unity. The void ratio of coarse grained soils...

Soil Structure and Clay Mineralogy Soil Structure Geometric arrangement of soil particles with respect to one another is known as soil structure. Depending upon the particle size and mode of formation, the following types are found. Single Grained Structure Found in coarse grained soils, like gravel, sand. The major cause for formation is gravitational force. Here the surface forces are negligible. Under the influence of gravitational forces, the grains will assume a particle to particle contact referred to as single grained structure. Single grained structure may be loose or dense as shown below. (a) Loosest state (b) Densest state Honey-comb Structure It is possible for fine sands or silts. Both gravitational force and surface force are responsible. Such a structure can support loads, only under static conditions. Under vibrations and shocks, the structure collapses and large deformations take place. Flocculated Structure This structure occurs in clays. Clay particles h...

Qualities of Good Timber - Building Material - Civil Engineering

-
Qualities of Good Timber Following are the characteristics or qualities of a good timber: 1. Appearance quality of Good Timber:  A freshly cut surface of timber should exhibit hard and shining appearance. 2. Colour quality of Good Timber  :  The colour of timber should preferably be dark. The light colour usually indicates timber with low strength. 3. Defects   quality of Good Timber :  A good timber should be free from serious defects, e.g., dead knots, fl aws, shakes, etc. 4. Durability   quality of Good Timber : A good timber should be durable. It should be capable of resisting the actions of fungi insects, chemicals, physical agencies and mechanical agencies. 5. Elasticity   quality of Good Timber :  This is the property by which timber returns to its original shape when load causing its deformation is removed. This is a sought after property of timber when it is used for making bow, carriage shafts, sport goods, etc. 6. Fibres   quality ...

Natural Seasoning and Artificial Seasoning of Timber

-
Differences between Natural Seasoning and Artificial Seasoning Natural Seasoning  It is difficult to reduce the moisture content below 15–18% It is simple and economical. It is more liable to attack of insects and fungi. It requires more space for stacking. It is a slow process. It gives stronger timber. Artificial Seasoning The moisture content can be reduced to any desired level. It gives weaker timber. It is a quick process. It requires less space for stacking. It is less liable to attack of fungi. It is expensive and highly technical.
