HOW TO DETERMINE WEIGHT VOLUME RELATIONSHIP OF SOIL? [STEP BY STEP]

Weight volume relationship of soil

WEIGHT VOLUME RELATIONSHIP OF SOIL The physical properties of a soil give insight as to the identification of the soil and the determination of its characteristics and load response. These properties can be determined by performing a laboratory analysis on undisturbed soil samples obtained during the test boring process. The laboratory analysis should be performed … Read more

2 TEST METHODS TO MEASURE DENSITY OF SOIL ON SITE

Measurement of Soil Compaction in the Field It is necessary in many instances to know the wet/dry densities of the soil in the field, especially before planning activities such as compaction. The same becomes particularly important in instances such as the construction of earth dams, embankments etc. to control the field compaction, that is, to … Read more

HOW TO DETERMINE UNIT WEIGHT OR DENSITY OF SOIL?

Density Test of Soil Purpose: This lab is performed to determine the in-place density of undisturbed soil obtained by pushing or drilling a thin-walled cylinder. The bulk density is the ratio of mass of moist soil to the volume of the soil sample, and the dry density is the ratio of the mass of the … Read more

6 MAJOR TYPES OF SOIL STRUCTURES OF DIFFERENT SOIL DEPOSITS

SOIL STRUCTURE / SOIL FABRIC The term soil structure in general, refers to the arrangement or state of aggregation of particles in a soil mass. But deeper understanding of soil structure demands consideration of mineralogical composition, shape and orientation of soil particles; the nature and properties of soil water, and the forces of interaction between … Read more

3 PRIMARY COMPONENTS CONTRIBUTING SETTLEMENT OF SOIL

3 primary components contributing settlement of soil

Components Contributing Settlement of Soil Total settlement ρ in mm, which is the response of stress applied to the soil, may be calculated as the sum of three components ρ = ρi + ρc + ρs Where, ρ = Total settlement, mm ρi = Immediate or distortion settlement, mm ρc = Primary consolidation settlement, mm … Read more

WHAT ARE THE ENGINEERING PROPERTIES OF SOIL?

engineering properties of soil

Engineering Properties of Soil The following properties of soil are taken into consideration while dealing with soil as a construction material. Cohesion Angle of internal friction Capillarity Permeability Elasticity Compressibility 1. Cohesion It is the internal molecular attraction which resists the rupture or shear of a material. Cohesion is derived in the fine grained soils … Read more
