The seventh FT cycle can be considered an approximate threshold for cohesive soils to generate distinct physico-mechanical properties.

Physico mechanical properties of soil. Physical and mechanical properties of soils the Need for the study of physico-mechanical properties of soil for the sake of durability of construction. To perform quality construction it is necessary to consider all. It is first necessary to investigate the soil in areas designated for construction.

It is known that even within one section of. The results of the study about soil physico-chemical soil properties are shown below table 1 and 2. Those tables are sorted in two main groups to separate physical and geological contents from chemical ones.

Taken samples and their geological properties ordered in. This physico-chemical study of soil is based on various parameters like pH electrical conductivity texture moisture temperature soil organic matter available nitrogen phosphorus and. The physico-chemical analysis consisted in determination of the humidity content the structure texture and pH of the soil.

The results of experiments related to the humidity showed that the soil humidity in the forest 1834-3477 was higher than the humidity determined from the surface tailings of Rades dump 1415 - 2239. Role of Physico-Chemical Properties in Soil Quality pH pH is a most important physical properties of soilIt having great effects on solute concentration and absorption in soil3. Soil pH is an important consideration for farmers and gardeners for several reason including the fact that.

Many chemical properties of soils centre round the soil reaction. As regards their nature some soils are neutral some are acidic and some basic. The acidity alkalinity and neutrality of soils are described in terms of hydrogen ion concentrations or pH values.

In case of undisturbed soil samples resistivity decreased as much as sixteen fold 494 to 32 Ohm-m for an increase of saturation from 31 to 100. Furthermore the resistivity results were different for the specimens at a specific degree of saturation because of varied surface activity and isomorphous substitution of clayey soils. Soil physio-mechanical properties significantly decreased after brittle failure.

Soil stabilisation can be stabilisation with such as plant juices straw natural oils jutes coir fibers animals dung different types of geogrids fibers etc. The seventh FT cycle can be considered an approximate threshold for cohesive soils to generate distinct physico-mechanical properties. Therefore the approximate number of FT sequences of a site must be determined prior to the construction of light structures eg.

Roads and concrete coverings because the variability of soil conditions depends on these FT cycles.

Elastic Modulus Deformation modulus and Poissons ratio Specific gravity density unit weight Uniaxial compressive strength Porosity void ratio Tensile strength.

Soil has a surprisingly diverse set of mechanical properties. The empirical and theoretical study of soil mechanics has progressed to the point where soil engineers are able to consider a wide variety of mechanical properties when they design structures that involve large quantities of soil.
