This method determines the specific gravity of soils by means of a pycnometer.

Determines the relationship between the moisture content and density of soils when compacted in a given mold of a given size with a 4.54 kg (10 lb) rammer dropped from a height of 457 mm. Depending on the material being tested, one of the four following methods should be used:

Method A- A101.60 mm (4 in) mold: Soil material passing a 4.75

Method B- A 152.40 mm (6 in) mold: Soil material passing a 4.75 (No. 4) sieve

Method C- A 101.60mm (4 in) mold: Soil material passing a 19.0 (3/4 in) sieve

Method D- A 152.40 mm (6 in) mold: Soil material passing a 19.0 mm (3/4 in) sieve

This test method provides an approximate value of the strength of cohesive soils in terms of total stresses.

Determines the unconfined compressive strength of cohesive soil in the undisturbed, remolded, or compacted condition, using strain-controlled application of the axial load. (Not a substitute for T 296.)

Covers procedures for determining the magnitude and rate of consolidation of soil when it is restrained laterally and drained axially while subjected to incrementally applied controlled-stress loading. Alternative methods are as follows:

	Method A- Performed with constant load increment duration of 24 hours, or multiples thereof.
	Method B- Time deformation readings are required on all load increments. Successive load increments are applied after 100 % primary consolidation is reached, or at constant time increments as described in Test Method A.

Determines the consolidated drained shear strength of a soil material in direct shear.

Best suited to a consolidated drained test because the drainage paths through the test specimen are short, thereby allowing excess pore pressures to be dissipated fairly rapidly.

Not suited to the development of exact stress-strain relationships within the test specimen because of the non-uniform distribution of shearing stresses and displacements.

Test determines the moisture content of soils, which by definition is the percentage of the mass of water in a given mass of soil to the mass of the solid particles.

Test method calculates total stresses on, and axial compression of, the test specimen by measurement of axial load and axial deformation

This test calculates total and effective stresses on, and axial compression of the test specimen by measurement of axial load, axial deformation, and pore-water pressure.

Generally three specimens are tested at different effective consolidation stresses to define a strength envelope.

Used to prepare samples for particle-size and plasticity tests where it is desired to determine test values on air-dried samples, or where it is known that air drying does not have an effect on test results relative to samples prepared in accordance with Practice D2217.

Determines the distribution of particle sizes in soils.

Used to establish a relationship between the dry unit weight and the water content for the soil. This data, when plotted, represents a curvilinear relationship known as the compaction curve.

The values of optimum water content and standard maximum dry unit weight are determined from the compaction curve.

Determines specific gravity of soil solids by means of a water pycnometer. The specific gravity of a soil solids is used in calculating the phase relationships of soils, such as void ratio and degree of saturation.

Soil placed as engineering fill is compacted to a dense state to obtain satisfactory engineering properties such as, shear strength, compressibility, or permeability.

Lab compaction tests provide the basis for determining the percent compaction and water content needed to achieve the required engineering properties, and for controlling construction to assure that the required compaction and water contents are achieved.

Primary purpose of this test is to quickly obtain the approximate compressive strength of soils that possess sufficient cohesion to permit testing in the unconfined state.

Determines the water content by mass of soil, rock, and similar materials where the reduction in mass by drying is due to loss of water. Water content is calculated using the mass of water and the mass of the dry specimen.

Data from this test is used to estimate the magnitude and rate of both differential and total settlement of a structure or earthfill. Estimates of this type are of key importance in the design of engineered structures and the evaluation of their performance.

Determines the strength and stress-strain relationships of a cylindrical specimen of either undisturbed or remolded cohesive soil. Provides data for the measurement of the total stresses applied to the specimen.

Determines the consolidated drained shear strength of a soil material in direct shear. Best suited to the rapid determination of consolidated drained strength properties.

Test can be made on all soil materials and undisturbed, remolded or compacted materials. (Limit on maximum particle size.)

Used to uncover the liquid limit, plastic limit, and the plasticity index of soils.

This test is used to determine the strength and stress-strain relationships of a cylindrical specimen of either an undisturbed or remolded saturated cohesive soil. Applicable to field conditions where soils that have been fully consolidated under one set of stresses are subjected to a change in stress without time for further consolidation to take place, and the field stress conditions are similar to those in the test methods.

This test includes procedures for making and curing cylinder and beam specimens from representative samples of fresh concrete foe a construction project.

Not satisfactory for making specimens from concrete not having measurable slump or requiring other shapes of specimens.

Determines compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. Limited to concrete having a unit weight in excess of 50lb/ft³

This test includes obtaining, preparing, and testing (I) cores drilled from concrete for length or compressive strength or splitting tensile strength determinations and (2) beams sawed from concrete for flexural strength determinations.

Determines the flexural strength of concrete by the use of a simple beam with third-point loading. Results may be used to determine compliance with specifications or as a basis for proportioning, mixing, and placement operations. Used in testing concrete for the construction of slabs and pavements.

Determines density of freshly mixed concrete and gives formulas for calculating the yield, cement content and air content of the concrete.

Test results are intended to provide the user with a procedure to determine slump of plastic hydraulic-cement concretes.

Identifies slump of hydraulic-cement concrete, both in the laboratory and in the field.

This test determines the air content of freshly mixed concrete containing any type of aggregate, whether it be dense, cellular, or lightweight.
