The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, and liquid limit.

Moisture content of soil is defined as the ratio of mass of water to the mass of solids present in the soil sample.

Relative density, or specific gravity, is the ratio of the density of a substance to the density of a given reference material.

The natural content also called natural moisture content is the ratio of the weight of water to the weight of the solids in  given mass of soil.

Used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen.

This is a quick way of indicating the potential for dispersion and tunneling susceptibility of soils.

Compressive strength is measured by breaking cylindrical concrete specimens in a compression-testing machine. Compression strength is calculated from the failure load divided by the cross-sectional are resisting the load and reported units of pound-force per square inch (psi) or megapascals (MPa).

Aggregates are tested for strength, toughness, hardness, shape, and water absorption.

Measures the size distribution, or amount of coarse and fine aggregates in a sample.

Specific gravity test of aggregates is done to measure the strength or quality of the material.

Determines the water holding capacity of the coarse and fine aggregates.
