The above operation shall be repeated while the sample is gradually dried, and when the fine aggregates in the form of a cone slump for the first time as the flow cone is pulled up, the condition of the sample at this moment shall be regarded as the saturated surface-dry condition. a Notes (2) T
14、he operation of 3.3 may be difficult in some cases due to the particle form or grading. In such cases, the fine aggregates remaining after the particles smaller than O. 15 mm (particles which pass the standard sieve of 150 um specified in JIS Z 8801) are screend off may be used as the sample. In tha
15、t case, the use of such a sample shall be supplementarily stated in the report. The fine aggregates shall be packed in the flow cone flowing gradually and uniformly. In addition, an excess amount of the sample shall.be packed in such a degree as to eliminate the necessity of adding the sample during
16、 or after the subsequent compacting operation. (3) (4) The flow cone shall be lightly tapped with the tip of a tamping rod from positions about 10 mm apart from the surface of the flow cone. The time required for tapping 10 times shall preferably be about 5 sec. 3.4 About 300 g each of the sample in
