Other cement contents can be used at the asmt request. 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.

To determine the maximum density and optimum water content of a sample using standard effort. To determine the permeability of cohesive soils by the falling head method.

Active Risk Management

Moist samples are first dried out to constant mass in the convection oven, then the sample is pulverized, split, and reduced to the required size. To aid in preparing a sample for other physical tests. A shelby tube sample is needed to perform this procedure. To dertermine the one-dimensional consolidation parameters of an undisturbed sample. Sample size varies depending on the physical time requested.

None Estimated Testing Length: The permeability analysis is only to be used to aid the stormwater engineer in his design. An average specific gravity is developed from three different sets of tests. To determine the particle size distribution of soils to aid in classification. A shelby tube sample undisturbed sample is needed to perform this procedure. Specific Gravity of Soil Test Purpose: To determine the water content in which a soil turns from a liquid state to a plastic state.

Two full 5-gallon buckets of material are needed for this procedure. Dry Preparation of Soil Test Purpose: Where other physical tests are performed, moisture contents 4d21 included for no additional charge. Resistivity of Soil and Water Test Purpose: To determine the pH value of soil and water. Additional break days can be included in the report for an additional charge.

To evaluate the bearing properties of samples that are used for base, stabilized subgrade, subgrade, or embankment material used in the state of Florida. A minimum of grams is required for the procedure. Contact our laboratory for special shipping requirements and procedures for undisturbed samples.

The Munsel color chart is used to determine material color. To determine the resistivity value of soil and water. Used for most physical tests D Large Samples: This test is required for soil classification purposes axtm cohesive soils. Chloride of Soil dd421 Water FM Soil sample must display cohesive properties to perform this procedure.

Sample size varies depending on the test specification requested. Varying amounts of soil are needed depending on the physical tests required for classification. The standard EGS sieve set is as follows: To determine the 3-day and 7-day compressive strength d4421 a soil-cement series.
