Weigh & record the dry mass after cooling in a dessicator. (M1). 6.1.3 The following procedure to conduct the test shall be followed: 1. For some materials, e.g all in aggregates or hoggin, the particle size distribution may result in excess mass on one or more sieves particularly on the finer sizes. a. Subdivide the test portion into two or more sub-portions. Determine the particle size distribution for each portion and combine the results for the purpose of reporting. b. Separate the test portion on an appropriate sieve. Weight the retained and passing fractions to determine the proportion of each present. 2. Washing and sieving method a. Preliminary separation. b. Wet both sides of a 75um test sieve. Mount the sieves in such a way that the suspension passing the test sieve can be run to waste or, when required, collected in suitable vessel. c. Place the weighed oven dried test portion in a container and add sufficient water to half fill the container. Agitate the contents so that particles smaller than 75um are completely separated from the coarser particles. d. Continue washing the coarse residue until the water passing the test sieve is clear and then wash all the residues from the container and sieves into the tray. Remove excess free water by careful decantation through the test sieve, avoiding transfer of solids. e. Dry the residue in the oven until the constant mass is achieved. Cool, weigh and record as (M2). f. Determine the mass of material passing the test sieve as (M1) (M2). 3. Sieving the dried residue a. Nest the clean and dry sieves on a fitting receiver in order of increase
aperture size from the bottom to top. b. Shake the sieves for a sufficient time to separate the test sample into the size fractions determined by the sieve apertures used. c. When sieving is done start with the coarsest sieve and shake each sieve separately over a clean tray. Do not force materials through the sieve by hand pressure but placing of particles is permitted. d. Record any extraneous material such as clay lumps and remove from the sieve for separate weighing. e. Do not apply pressure to the surface of the sieve to force through the mesh. Used light brush to clear the sieve openings. f. To prevent blinding of the sieve apertures by overloading followed the weighing sample masses. g. Weigh the material retained on each sieve, together with any material cleaned from the mesh, on completion of sieving on that sieve. 6.1.4 Calculation and expression of results: Calculate the mass retained on each sieve as a percentage of the original dry mass (M1). For the mass of material passing the finest sieve, add that passing during washing (M1-M2) to that found during the dry sieving. Calculate the mass passing each sieve as a cumulative percentage of the total sample pass. 6.1.5 Format attached

6.13 ASTM D1556 Standard test Methods for Density and Unit Weight of Soil in Place by the Sand-Cone Method. 6.13.1 The following apparatus shall be used: a. Chisel b. Sand Cone & Plate c. Hammer d. Weighing Scale e. Plastic bag f. Drying Oven 6.13.2 The following procedure to conduct the test shall be followed: a. Determine first the density of a dry sand (calibrated sand). 6.13.3 Format attached b. Select a location that is representative of the area to be tested and determine the density of soil. c. Put the sand cone plate, dig the test hole through the center hole in the base plate, being careful to avoid disturbing the soil that will bound the hole. d. Invert the sand cone apparatus and seat the sand cone funnel into the flanged hole. Open the valve and allow the sand to fill the hole. When the sand stops flowing, closed the valve. e. Determine the mass of the apparatus with the remaining sand, record, and calculate the mass of sand in used. f. Determine and record the mass of the moist material that was removed from the test hole. g. From the materials taken from hole get sample for the moisture content. h. Calculate the wet unit weight by dividing materials taken from hole from the volume of hole. i. Calculate the dry unit weight by dividing the wet unit weight over moisture content. j. Then we can get the percent compaction by dividing the actual dry density over maximum dry density from test method ASTM D-1557.
