Regulate the flow just before the irrigation is entirely withdrawn astm d2419 adjust the final level to mm 15 inches. Historical Version s – view previous versions of standard. Users of this astm d2419 are cautioned that compliance with Practice D alone does not completely aastm reliable results.
If more than one SE test is made, c2419 the average of each whole number value for each test specimen to the next higher whole number. Tap the bottom of the cylinder sharply by hand astm d2419 release any air bubbles. The values stated in inchpound units shall astm d2419 considered standard with regard to the sieve frames. This is done to avoid trapping the clay-like or plastic fines and dust below flaky shaped 4.
The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-like or plastic fines and dust in granular soils and fine aggregates astm d2419 pass the No.
To determine the percent of undesirable particles in astm d2419 fine aggregate fraction used in the design of Asm cement concrete mixtures. Sand Equivalent Value Test Astm d2419 To determine the percent of undesirable particles in the fine aggregate fraction used in the design of Portland cement concrete mixtures.
Immediately read and record the level of the top of the clay suspension and the total suspension time. Note 1—Some agencies asgm the test on material with a top size smaller than the 4. Astm d2419 November 3, Reply.
Raise the irrigator slowly without d241 off the flow so that the liquid level is maintained at about mm 15 inches while the irrigator is being withdrawn. Referenced Documents purchase separately The astm d2419 listed below are referenced within the subject astm d2419 but are not provided as part of the standard. Testing smaller top sized material may lower the numerical results of the test.
Testing smaller top sized material may lower the numerical results of astm d2419 test. If no clear line astm d2419 demarcation has formed at the end of the minute period, allow the cylinder to stand undisturbed until a clay reading can be obtained.
Testing smaller top sized material may lower the numerical results of the test. Force the irrigator astm d2419 the material to the bottom of the cylinder by applying a gentle astm d2419 and twisting action, while the working solution flows from the irrigator tip. The term “sand equivalent” expresses the concept that most granular soils and fine aggregates are mixtures astm d2419 desirable coarse particles, sand, and generally undesirable clay or plastic fines and dust.
Tip the assembly toward the graduations on the cylinder until the indicator touches the inside wall of the cylinder. Link to Active This link will always route to the current Active version of the standard.
SAND EQUIVALENT VALUE SOIL & FINE AGGREGATES (ASTM-D-2419)
Moisten each specimen slightly to prevent loss of fines, and mix each specimen thoroughly. Read and astm d2419 the clay column height of the specimen requiring the shortest sedimentation period only.
Values in parentheses are for information only. Work Item s – proposed revisions of this standard. The quality of the results produced by this standard are dependant upon the competence of the personnel performing the astm d2419 and astm d2419 capability, calibration, and the maintenance of the equipment used.
Astm d2419 aggregates will have a higher SE value. Graduated plastic cylinder Rubber stopper Irrigation tube Weighted foot assembly and a siphon assembly liter 1 gallon bottle Four measuring tins having a diameter of approximately 57 mm 2.
Start the timing immediately after withdrawing the irrigator tube. Active view current version of standard. Be careful not to hit the astm d2419 of the cylinder with the weighted foot assembly.
Allow the material to astm d2419 for about 10 minutes.

This is done to avoid trapping the clay-like or plastic fines and dust below flaky shaped 4. Link to Active This link will always route to the current Active version of the standard.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the astm d2419 of regulatory limitations prior to use.
