This is done to avoid trapping the clay-like or plastic fines and dust below flaky shaped No. Place each of the four specimens in a closed can. It is the responsibility of astm d2419 user of this standard to establish astm d2419 safety astk health practices and determine the applicability of regulatory limitations prior to use. The purpose of this test method is to astm d2419, under standard conditions, the relative proportions of clay-size or plastic fines and dust in granular soils and fine aggregates that pass asttm 4.

Tip the assembly toward the graduations on the cylinder until the indicator touches the inside wall of d22419 cylinder. Testing smaller top sized material may lower the numerical results of the test.

The term “sand equivalent” expresses the concept that most granular soils and fine aggregates are mixtures of desirable coarse particles, sand, and generally undesirable clay or plastic fines and dust. If more than astm d2419 SE test is made, take the average d2491 each whole number value for each test specimen to the next higher whole number.

The method is also applicable for determining the relative proportions of astm d2419 fine dust or claylike material in soils. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not astm d2419 as part of the standard.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Calculation Report the result as a percent, always carrying the sand equivalent SE up to the next higher whole number do not use any decimals.

Force the irrigator through the material to the bottom of the astm d2419 by applying a gentle stabbing and astm d2419 action, while the astm d2419 solution flows from the irrigator tip.

Raise the irrigator slowly without shutting off the flow so that the liquid level is maintained at about mm 15 inches while the irrigator is astm d2419 withdrawn. Start the timing astm d2419 after withdrawing the irrigator tube. Read and record the clay column height of the specimen requiring the shortest sedimentation period only. This is done to avoid trapping the clay-size or plastic fines and dust below flaky shaped 4. If the total sedimentation time exceeds 30 minutes, rerun the test on the other prepared samples astm d2419 the same material.

The values stated in inchpound units shall be considered standard with regard to the sieve frames. Cleaner aggregates will have a higher SE value. Historical Version s – view previous versions of standard. Reliable results depend on many factors: Note 1—Some agencies perform the test on material with a top size smaller than the 4.

Calculate the sand equivalent to the nearest 0. It is the responsibility of the user of this standard astm d2419 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Place the stopper on the cylinder and vigorously shake it manually to x2419 the material. Be careful not to hit the mouth of the cylinder with the weighted foot assembly. Allow the cylinder to now stand undisturbed for 20 minutes. Testing smaller top sized material may lower astm d2419 numerical results astm d2419 the test.

This is done to avoid trapping the clay-like or plastic fines and dust below flaky shaped 4. Remove astm d2419 cylinder from the mechanical shaker, remove astm d2419 stopper, and set it upright on the table. Insert the irrigator tube into the cylinder and rinse material from the inside surface as it is lowered. This is done to avoid trapping the clay-like or plastic fines and dust below flaky shaped 4.

Work Item asrm – proposed revisions of this standard. Place the cylinder in the mechanical sand equivalent shaker, set the timer, and allow the astm d2419 to run for 45 seconds. Link to Active This link will always route to the current Active astmm of the standard.

The astm d2419 of the results produced by this standard are dependant upon the competence of astm d2419 personnel performing the procedure and the astm d2419, calibration, and the maintenance of the equipment used.

For fine aggregates containing clean dust of fracture astm d2419 particles that are not clay mineralstest results will depend on the amount of fines present in the material. 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 that pass the 4.

Testing smaller top sized material astm d2419 lower the numerical results of the test. Link to Active This link astm d2419 always route to the current Active version of the standard. 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 astm d2419 fine aggregates that pass the 4.

Sand Equivalent Value Test Purpose To determine the percent of undesirable particles in the fine aggregate fraction used in the design of Portland cement concrete mixtures.

This is referred to as the clay reading. To determine the percent of undesirable particles in the fine aggregate fraction used in the design of Portland cement concrete mixtures.
