Agronomy

Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation.

See Atterberg limits and Agronomy

Albert Mauritz Atterberg (19 March 1846 – 4 April 1916) was a Swedish chemist and agricultural scientist who created the Atterberg limits, which are commonly referred to by geotechnical engineers and engineering geologists today.

See Atterberg limits and Albert Atterberg

Arthur Casagrande

Arthur Casagrande (August 28, 1902 – September 6, 1981) was an American civil engineer born in Austria-Hungary who made important contributions to the fields of engineering geology and geotechnical engineering during its infancy.

ASTM International

ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services.

See Atterberg limits and ASTM International

Austria

Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps.

See Atterberg limits and Austria

Chemist

A chemist (from Greek chēm(ía) alchemy; replacing chymist from Medieval Latin alchemist) is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field.

See Atterberg limits and Chemist

Clay

Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, Al2Si2O5(OH)4).

See Atterberg limits and Clay

Compressibility

In thermodynamics and fluid mechanics, the compressibility (also known as the coefficient of compressibility or, if the temperature is held constant, the isothermal compressibility) is a measure of the instantaneous relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.

See Atterberg limits and Compressibility

Fall cone test

The Fall cone test, also called the cone penetrometer test or the Vasiljev cone test, is an alternative method to the Casagrande method for measuring the Liquid Limit of a soil sample proposed in 1942 by the Russian researcher Piotr Vasiljev (Пё́тр Васи́льев) and first mentioned in the Russian standard GOST 5184 from 1949.

See Atterberg limits and Fall cone test

Geotechnical engineering

Geotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials.

See Atterberg limits and Geotechnical engineering

Granulometry (morphology)

In mathematical morphology, granulometry is an approach to compute a size distribution of grains in binary images, using a series of morphological opening operations.

See Atterberg limits and Granulometry (morphology)

Gravimetric analysis

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass.

See Atterberg limits and Gravimetric analysis

Karl von Terzaghi

Karl von Terzaghi (October 2, 1883 – October 25, 1963) was an Austrian mechanical engineer, geotechnical engineer, and geologist known as the "father of soil mechanics and geotechnical engineering".

See Atterberg limits and Karl von Terzaghi

Liquid

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure.

See Atterberg limits and Liquid

Permeability of soils

A number of factors affect the permeability of soils, from particle size, impurities in the water, void ratio, the degree of saturation, and adsorbed water, to entrapped air and organic material.

See Atterberg limits and Permeability of soils

Plasticity (physics)

In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces.

See Atterberg limits and Plasticity (physics)

Sand

Sand is a granular material composed of finely divided mineral particles.

See Atterberg limits and Sand

Shear strength

In engineering, shear strength is the strength of a material or component against the type of yield or structural failure when the material or component fails in shear.

See Atterberg limits and Shear strength

Shear strength (soil)

Shear strength is a term used in soil mechanics to describe the magnitude of the shear stress that a soil can sustain.

See Atterberg limits and Shear strength (soil)

Silt

Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz.

See Atterberg limits and Silt

Smectite

A smectite is a mineral mixture of various swelling sheet silicates (phyllosilicates), which have a three-layer 2:1 (TOT) structure and belong to the clay minerals.

See Atterberg limits and Smectite

Soil

Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support the life of plants and soil organisms.

See Atterberg limits and Soil

Soil mechanics

Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils.

See Atterberg limits and Soil mechanics

Strength of materials

The field of strength of materials (also called mechanics of materials) typically refers to various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts.

See Atterberg limits and Strength of materials

Sweden

Sweden, formally the Kingdom of Sweden, is a Nordic country located on the Scandinavian Peninsula in Northern Europe.

See Atterberg limits and Sweden

United States Army Corps of Engineers

The United States Army Corps of Engineers (USACE) is the military engineering branch of the United States Army.

Water content

Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood.
