Phase problems are very important in soil engineering. Below are given most commonly used formulas to solve problems related to weight volume calculations. The notations used in these formulas are as follows, γb = Bulk density of soil mass γw = Density of water γsat = Saturated density γsub = Submerged density G = … Read more
On Site Identification of Silt & Clay The distinction between silt & clay cannot be based on particle size because the significant physical properties of the two materials are related only indirectly to the size of particles. Furthermore, since both are microscopic, physical properties other than particle size must be used as criteria for field … Read more
Soil in an engineering sense is a relatively loose agglomerate of mineral and organic materials and sediments found above bedrock. Texturally the soil is divided into two primary groups. Coarse grained soil Fine grained soil The behavior of coarse grained soil is different from fine grained soil. The method of describing coarse grained soil is … Read more
