Procedure c421 broken into two different procedures: To determine the resistivity value of soil and water. Normally 5 days or less. To determine the percentage of organic material present in a sample.

Where other physical tests are performed, moisture contents are included for no additional charge. A full Sieve Analysis is also included in this test. Resistivity of Soil and Water Test Purpose: Specific Gravity of Soil Test Purpose: Sulfate of Soil and Water Test Purpose: To determine the unconfined compressive strength of an undisturbed cohesive soil.

The Munsel color chart is used to determine material color. Chloride of Soil and Water Test Purpose: To determine the maximum density and optimum water content of a sample using standard effort.

Proper sample sealing is required to obtain accurate results. To determine the percentage of moisture that is present in a given soil sample. Sample size varies depending on the test specification requested. A shelby tube sample undisturbed sample is needed to perform this procedure. Used for most physical tests D Large Aastm Additional break days can be included in the report for an additional charge. To determine the pH value of soil and water. To determine the Unified soil classification of a given sample.

To aid in preparing a sample for other physical tests. None Back to top FM Contact our laboratory for more information on sample r421 and shipping options.

Soil sample must display cohesive properties to perform this procedure. To determine the maximum density and optimum water content of a soil-cement series using modified effort.

Time dependant on material type encountered. Sample size varies depending on the sample gradation results and material type. To dertermine the one-dimensional consolidation parameters of an undisturbed sample.

ASTM D Standard

This test is required for soil classification purposes for cohesive soils. An average specific gravity is developed from three different sets of tests. To determine the consolidated drained shear strength of a soil material in direct shear.

This procedure only sstm to cohesive soils. To determine the water content in which a soil turns from a liquid state to a d4221 state. To evaluate the bearing properties of samples that are used for asfm, stabilized subgrade, subgrade, or embankment material used in the state of Florida. Whether you need advanced geotechnical analysis or general soil classification, EGS has the capacity to accomplish a job of any size with a full time engineer on staff in our laboratory, you can be assured that you are getting the highest quality data in the business.

Active Risk Management

All prerequisite tests d21 included in the price of the compaction series. To determine the specific gravity of soils. To determine the percentage of particle size that is finer than 0.

Dry Preparation of Soil Test Purpose: Modified Proctor Test Test Purpose: The permeability value should not be used as the ‘in situ’ infiltration rate of a material in the field.

This procedure involves preparation of a test specimen for other physical tests. A shelby tube sample is needed to perform this procedure.

Sample size varies depending on the physical time requested.
