Which of the following amounts of field samples can be collected, according to * C136, for use in sieve analysis if the aggregate sizes ranges from 4.75 mm and smaller? 800 g 900 g 1.00 kg 1.50 kg Refer to determination of relative density and absorption of fine aggregates. What flask into which the fine aggregate test sample can be readily introduced and in which the volume content can be reproduced within ± 0.1 cm^3? O Graduated Cylinder OPyncnometer O Le Chatelier Flask OBalance According to the ASTM C128, which of the following sizes is the required test specimen for the standard test method for relative density and absorption of fine aggregate? 700 g 800 g 600 g O 1000 g In reducing the field sample to testing size, what method shall be used for fine aggregates having free moisture on the surfaces? C None of the above Method B Method A O Mechanical Splitter Arrange the following steps in sequence in performing the miniature stockpile sampling. (1) With the last turning, shovel the entire sample into a conical pile by depositing each shovelful on top of the preceding one. If desired, flatten the conical pile to a uniform thickness and diameter by pressing down the apex with a shovel so that each quarter sector of the resulting pile will contain the material originally in it; (2) Place the original sample of damp fine aggregate on a hard, clean, and level surface where there will be neither loss of material nor the accidental addition of foreign material; (3) Obtain a sample for each test by selecting at least five increments of material at random locations from the miniature stockpile, using any of the sampling devices; (4) Mix the material thoroughly by turning the entire sample over three times.
