Mechanical Analysis of Soil
As complex as it is, soil can be described simply. It consists of four major components: air, water, organic matter, and mineral matter.
Mechanical Analysis of Soil
The structure of soil determines its suitability for concrete, road subsurface, building foundation, or filter media. Soil has four constituent parts:
Sand is any soil particle larger than 0.06 millimeters (0.002 inches). Silt is any soil particle from 0.002 - 0.06 millimeters. Clay is any soil particle below 0.002 millimeters, including colloidal clay so small it does not settle out of suspension in water.

Mechanical Analysis of Soil
The percentage distribution of those parts determines soil structure. Mechanical analysis is the determination of the size range of particles present in a soil, expressed as a percentage of the total dry weight. There are two methods generally used to find the particle– size distribution of soil:
(1) sieve analysis – for particle sizes larger than 0.075 mm in diameter, and (2) hydrometer analysis – for particle sizes smaller than 0.075 mm in diameter.

Sieve Analysis
Sieve analysis consists of shaking the soil sample through a set of sieves that have progressively smaller openings.
